(-4/3)^2 = 16/6 because squaring of negative numbers always leads to positive numbers

Answer- 5g+ 69.50= 85  ; 3.1 (3)

An inequality is an equation with letters and number that sum to ONE whole.

In this case we have a flat cost, which is standalone and 5 dollars per gigabyte which is not standalone. Let G stand for each gigabyte.

This means our equation is 5g(five dollars times each gigabyte used) +69.50 that is gives. He has to keep his entire month under 85 dollars, which means our equation must equal 85. Now our equation will look like this.

Inequality- 5g+ 69.50= 85.

In order to solve how many gigabytes will be used we solve our equation backwards. We subtract 69.50 from 85,because we know that must has already been spent. This gives us 15.50. This means we will have to divided 15.50 into five dollars to see how many gigabytes are spent. 15.50 divided into five is 3.1 gigabytes.

This means Alexander will have to use 3.1 (or 3 if you have to round) gigabytes in order to spend 85 dollars or less per month.

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

15 units

Answer:

12

Step-by-step explanation:

a^2+b^2=c^2. This is the pythagorean theorem.

c^2-a^2=b^2.

Substitute c and a

13^2-5^2=b^2

169-25=b^2

144=b^2

sqrt144=b

b=12.

Hope this helps plz hit the crown :D

Step-by-step explanation:

C^2=A^2+B^2

C^2=13 A^2=5 B^2=?

13^2=5^2+B^2

169-25=B^2

B^2=144

\( \sqrt{144} \)

B=12

Answer:

Sid found the reciprocal of the scale factor.

Step-by-step explanation:

I know this because when finding scale factor the formula is the image/ pre-image so this means that if you substitude the known value you would get 20/4 which is equal to 5 and sid said the answer was 1/5 and the recipcal of that is 5.

Answer:

Sid calculated the scale factor to be One-fifth. What error, if any, did Sid make when he calculated the scale factor?  Option A

(A) Sid found the reciprocal of the scale factor.     100% Answer

Step-by-step explanation:

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Answer: Ok so I think that you would have to make both fractions have a denominator of 4. In that case you would have to multiply 1/2 by 2/2 (which would also be one). So 1/2 *2/2 = 2/4. So your pair would be 2/4 and 1/4. It's been a while since I've done this but I'm pretty sure this is how you do it. :)

Step-by-step explanation:

Answer:

Part 1. 28 miles

Part 2. 16^2 + 12^2 = c^2

Part 3. 8 miles. All work is in step by step explanation.

Part 4. 8 miles

Step-by-step explanation:

Part 1. The total distance that Jane travels biking and running is 28 miles. This is because we add 16 and 12 which is her total route.

Part 2. The Pythagorean theorem is a^2 + b^2 = c ^2. In this case, the variable a is Jane's bike route(16 miles), the variable b is Jane's running route(12 miles), and the variable c is the Trainer's biking route as given. If we replace all variables with the values in miles, the equation would be 16^2 + 12^2 = c^2.

Part 3. WORK USED FROM EQUATION

16^2 = 16*16 = 256

12^2 = 12*12 = 144

Now we replace the numbers with the exponents with the solved numbers.

256 + 144 = c^2

256 + 144 = 400

400 = c^2

c = sqrt400

c = 20

Finally, we take the value of c and subtract it from the total distance of Jane's route which is 28 miles(as explained above).

28 - 20 = 8.

Hence, the answer is 8 miles

frog (-6,-6)

fish (2,-5)

Pentagon (5,-1)

right triangle (6,2)

equilateral triangle (-5,-3)

crab (-2,2)

snail (6,-3)

In order to solve this problem, we need a few formulas to help us get to the answer:

The first formula we need is the Slope Formula:
\(\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}\)

where (x₁, y₁) and (x₂, y₂) are two different points.

The second formula we need is Point-Slope Form:
\(\displaystyle y - y_0 = m(x - x_0)\)

where (x₀, y₀) is a given point on the line and m is the slope.

Now, we can organize and define what the problem has given us:

We are first given information that a line passes through the points (6, 2) and (2, 4).

We are also given that the parallel line passes through (-1, 6).

Let's first find the slope of the line that passes through two points:

\(\displaystyle\begin{aligned}m & = \frac{4 - 2}{2 - 6} \\& = \frac{2}{-4} \\& = \boxed{ - \frac{1}{2} } \\\end{aligned}\)

∴ we know that the slope is equal to negative one-half.

Let's substitute in our slope into Point-Slope Form since parallel lines have the same slope:

\(\displaystyle y - y_0 = m(x - x_0) \Rightarrow y - y_0 = - \frac{1}{2} (x - x_0)\)

Recall that we were given the initial point (-1, 6). Let's also substitute this into Point-Slope Form:

\(\displaystyle \begin{aligned}y - y_0 = m(x - x_0) & \Rightarrow y - y_0 = - \frac{1}{2} (x - x_0) \\& \Rightarrow y - 6 = - \frac{1}{2} (x - -1) \\& \Rightarrow \boxed{ y - 6 = -\frac{1}{2}(x + 1) } \\\end{aligned}\)

∴ we have found that the point-slope form of the equation of a line that passes through the point (-1, 6) and is parallel to the line that passes through the points (6, 2) and (2, 4) is equal to:
\(\displaystyle \boxed{ y - 6 = -\frac{1}{2}(x + 1) }\)

Hope this helps!

Answer:

There are two ways to check if 3x+5=11 is true:

Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.

3x = 6

Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.

x = 2

You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)
