What would be the Y-intercept in equation #1 of the following system? (Graphing)

Mathematics

Serhud [2]3 years ago
5 0

I don't know what you mean by equation 1. I assume you mean x + y = 7 is equation 1.

If so, solve for y as step 1.

x + y = 7

y = - x + 7

The y-intercept is 7.

Your directions do not say to solve the system of equations.

If you need to solve by graphing, use DESMOS or your graphing calculator. The solution of the system of equations is the point on the graph where the two equations meet or touch each other.

1/8 (3d-2) = 1/4 (d+5)
tatiyna
OK, so for this equation, your goal is to get the d, and ONLY the d, on one side of the equation. So, to start out, you need to multiply the entire equation, meaning both sides, by 8 because we are trying to get rid of those pesky fractions.
8(1/8(3d-2)=1/4(d+5))
The equation then turns into this because the 8 and 4 cancelled out with the 8.
1(3d-2)=2(d+5)
Now, we need to distribute the left over numbers into the parenthesis.
3d-2=2d+10
And finally, we need to get the d's on one side, and the numbers on the other, so we subtract 2d from both sides and add the 2 to both sides. They then cancel out to make
d=12
Hope it helps!  :)

The value of y varies directly with x. If x = 8, then y = 96. What is the value of x when y = 168?
patriot [66]

Answer:

  • x = 14

Step-by-step explanation:

<u>Direct variation equation:</u>

  • y = kx, where k is constant of variation

<u>Given:</u>

  • 96 = 8k
  • k = 96/8
  • k = 12

<u>The equation is:</u>

  • y = 12x

<u>Find the value of x when y = 168:</u>

  • 168 = 12x
  • x = 168/12
  • x = 14
