Answer:

  1. proportional, 6

  2. not proportional

Step-by-step explanation:

<u>Table 1</u>

Each y-value is 6 times the corresponding x-value, so the variables are proportional, and y = 6 times x.

<u>Table 2</u>

The ratios of y to x are 2, 4, 8, so are not the same. The values are not proportional.

Y = 8x + 10<br><br> y = 2<br><br> whats the substitution ?
viva [34]

Answer:

Look at the explanation.

I'll be online so let me know if you still need help.

Step-by-step explanation.

A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.

The substitution is basically plugging in the y value to y = 8x + 10

If y = 2

and also y = 8x + 10

What do you think the substitution is?

I will literally pay you pls help me :(
vovikov84 [41]

The answer is 35

Since they are supplementary they both equal 180 degrees.

(3x+10)+(2x-5)=180

Add them up

5x-5=180

Subtract 5 from both sides

5x=180-5

5x=175

Divide 5 from both sides

x=35.

What is the value of n in the equation 1/2(n – 4) – 3 = 3 – (2n + 3)?
Travka [436]
Distribute 1/2 to <span>(n – 4):

</span>\frac{1}{2} \times n = \frac{1}{2}n
\frac{1}{2} \times -4 = -2
<span>
Subtract (2n + 3):

</span>- (2n + 3) = -2n -3
<span>
Your equation should now look like this:

</span>\frac{1}{2}n - 2 - 3 = 3 - 2n - 3
<span>
Combine like terms on both sides:

</span>-2 - 3 = -5
3 - 3 = 0
\frac{1}{2}n - 5 = -2n
<span>
Subtract 1/2n from both sides:

</span>-5 = -\frac{5}{2}n
<span>
Divide both sides by -5/2 to get n by itself:

</span>n = 2
<span>
The value of n is 2.</span>
