Answer:

  1. 72
  2. 24
<h2></h2>

Step-by-step explanation:

x = 4\\ y = -1 \\ z= -3\\2x(3y -4z)\\= 2(4) [3(-1)-4(-3)] = 8(-3+12)\\=8 (9)\\\\=72\\\\3(5x + 4z)\\3[5(4)+4(-3)]\\3(20-12)\\3(8)\\= 24

Suppose a parabola has an axis of symmetry at x = -8 , a maximum height of 2, and passes through the point (-7, -1). Write the e
lidiya [134]
As it has a maximum value the coefficient of x^2 will be negative

The vertex will be at (-8,2)  so in vertex form it is

y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:

-1  = a(-7+8)^2 + 2

-1 = a + 2  so a = -3

answer is  y = -3(x + 8)^2 + 2

in standard form this is y = -3x^2 -48x  - 190
