Answer:
- 5
Step-by-step explanation:
Given
3x = 21 ( divide both sides by 3 )
x = 7
Then
23 - 4x = 23 - 4(7) = 23 - 28 = - 5
An equation in the slope-intercept form y = mx + b the variable b is the y-intercept.
Or, if you replace the variable x with 0, you will also get the y-intercept.
y = 4(0) - 9
y = -9
So, the y-intercept is -9.

not for sure there might be a trick to the problem
Answer:
Step-by-step explanation:
The function y = 2x^2 + 4x has a parabolic graph that opens up.
*In factored form we have y = 2x(x + 2); if we set this equal to zero and solve for x, we obtain {-2, 0}, the roots of this function.
*The axis of symmetry is halfway between these roots: x = -1. The y-value of the vertex is the value of the function at x = -1: f(-1) = 2(-1)^2 + 4(-2) = -6. Thus, the vertex is (-1, -6).
* The y-intercept is (0, 0), since y = 0 when x = 0.
Graph the points shown and draw a smooth curve through them, remembering that this parabola opens up.
