Neko [114]

Answer:

x = 4

Given:

f(x) = -12x + 72

f(x) = 24

Step-by-step explanation:

$= > - 12x + 72 = 24 \\ \\ = > - 12x = 24 - 72 \\ \\ = > \cancel{- }12x = \cancel{-} 48 \\ \\ = > 12x = 48 \\ \\ = > x = \frac{48}{12} \\ \\ = > x = 4$

Which point is not on the graph of the equation y=10+x

RSB [31]

Answer:

C. (8, 2)

Step-by-step explanation:

To find which point is not on the graph, find which set of coordinates makes the equation incorrect.

When plugged into the equation, the point (8, 2) makes it incorrect:

y = 10 + x

2 = 10 + 8

2 = 18

2 $\neq$ 18

The equation is incorrect because 2 is not equal to 18.

So, the point that is not on the graph is C. (8, 2)

and because the is 10 white it would be 10/30

that should be the answer but if you have to work the total all together then it would be 15/30

hope this helps :)
