Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2x-y=8 y=x-3

Answer:

-34.5 > x

Step-by-step explanation:

The dot is on -34.5 and x is less than -34.5, so the line has to be pointing to the left.

Step-by-step explanation:

16x3=48x2=96-22=74 divided by 6=12.3

Answer:

1, 4 or 7

Step-by-step explanation:

The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.

adding 1 gets you 30, which we know is divisible by 3.

then, instead of trying every digit, we can note that

30 , 33 , 36 , 39 ....

are divisible by 3.

But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant

so, we want to find out if we can make 29 into 30, 33, or 36

adding 1 to 29 = 30

adding 4 to 29 = 33

adding 7 to 29 = 36

So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

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:
\(\displaystyle \boxed{ y - 6 = -\frac{1}{2}(x + 1) }\)

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

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

\(a=-15b-5\)

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:
