Answer:

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.

Step-by-step explanation:

c = 25       d = 20

1.875(25) - (25+0.5*20) =

46.875 - 35 =

Answer:

right angle

Obtuse angle describes the figure of the angle.

The correct option is C.

The angles are classified under the following types:

Acute Angle – an angle measure less than 90 degrees

Right Angle – an angle is exactly at 90 degrees

Obtuse Angle – an angle whose measure is greater than 90 degrees and less than 180 degrees

Straight Angle – an angle which is exactly at 180 degrees

Reflex Angle – an angle whose measure is greater than 180 degrees and less than 360 degrees

Full Angle – an angle whose measure is exactly at 360 degrees.

Given,

figure of an angle

∵ The drawn angle is more than 90° and and less than 180°

∴ It is an obtuse angle.

Hence, obtuse angle describes the figure of the angle.

Answer:

Step-by-step explanation:

Given the system of equations,

\(y=2x-3\\y=-x+3\)

We can substitute one equations into another since both equations solve for y. I will use the second equation for this example.

Step 1: Substitute

\(-x+3=2x-3\)

Step 2: Simplify

\(6=3x\\x=2\)

Now, we can easily substitute our x value into one of the equations.

Step 3: Substitute.. again

\(y=-2+3\\y=1\)

Solution: \((2,1)\)

Answer: 19.50

Step-by-step explanation:

Write a system of equations to represent the problem. Let x represent the cost of a binder, and let y represent the cost of a notebook.

Grace buys 4 binders and 7 notebooks for $26.50 total, so the equation 4x+7y=26.50 represents how much Grace spends.

Grace's friend buys 3 binders and 6 notebooks for $21.00 total, so the equation 3x+6y=21 represents how much her friend spends.

You can use this system of equations to find how much money Grace and her friend spend on notebooks:

4x+7y=26.50

3x+6y=21

Next, find how much Grace and her friend spent on notebooks. Start by finding the cost of one notebook. Use elimination to solve for y. .

3(4x+7y)=3(26.50)  

–

12x+21y = 79.50

–

4(3x+6y)=

–

4(21)  

–

12x–24y =  

–

84

–

3y =  

–

4.50

y = 1.50

Each notebook costs $1.50. Grace and her friend buy a total of 13 notebooks, so multiply to find how much money they spend on notebooks.

13$1.50=$19.50

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

The formula for finding original prices is o = s over 1 - d, in which o is the original price, s is the sale price, and d is the discount. Let’s go ahead and plug our numbers in: o = 75 over 1 - 0.2. (Remember 20% equals 20 ÷ 100.)

75 over 1 - 0.2 equals 75 over 0.8. Now we find out how much that is in whole numbers. 75 ÷ 0.8 = 93.75, o.

Answer:

y = -0.3x + 105

Step-by-step explanation:

x1 - x2 / y1 - y2 is the method to use to find the answer, so it

= (94.5-97.5) / (35-25) which

= (-3) / (10) which = -0.3.

That is m for ya, and for b,

Sub the first point (25, 97.5) into the equation of this line:

97.5 = (-0.3)*(25) + b => b = 97.5 - (-7.5) = 105

In conclusion, the equation is y = -0.3x + 105.

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

Step-by-step explanation:

A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.

From the given information, the five-number summary of the Jumping Jacks box plot is:

The range is the difference between the maximum and minimum values. Therefore, the range for the data is:

\(\sf Range = 52 - 15 = \boxed{\sf 37}\)

The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:

\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)

The range is 37, and the IQR is 23.
