Which ordered pair does NOT lie on the graph of h(x)=-2x + 7

goblinko [34]

Answer: A (-2, 3)

Step-by-step explanation:

1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.

2. Therefore, you have:

A. x=-2

$h(x)=-2(-2)+7=11$ (It does not lie on the graph).

B. x=--1

$h(x)=-2(-1)+7=9$ (It lies on the graph).

C. x=3

$h(x)=-2(3)+7=1$ (It lies on the graph).

D. x=4

$h(x)=-2(4)+7=-1$ (It lies on the graph).

Therefore, the answer is the option A.

1) g=-y+c/x, solve for X

Sindrei [870]

Answer:

the solution $x = \frac{c}{g-y}$

Step-by-step explanation:

Step 1:-

Given problem $g=\frac{-y+c}{x}$

here l.cm is x

$g = \frac{x y+c}{x}$

cross multiplication we get ,

$g x = x y +c$

Step 2:-

subtracting x y on both sides , we get

$g x - x y = c$

taking common 'x' we get,

$x(g-y) = c$

Final answer:-

$x = \frac{c}{g-y}$
