Answer:
I think its 15 + 5x
Step-by-step explanation:
The answer to the equation is X= 27
Answer:
X=1 - y/2
Step-by-step explanation:
2x = 2 - y
divide both sides by 2
x = 1 - y/2
General Idea:
W
hen we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)
When
, then P' is enlargement of P
When
, then P' is reduction of P
Applying the concept:
In the diagram given A'B'C' is enlargement of ABC. So the correct option will be option A.
, enlargement
Since you know the value of "x", you can plug in the value for "x" in the equation.
[When an exponent is negative, you move it to the other side of the fraction to make the exponent positive.]
For example:
or 
or y³
x = -2
f(x) = 9x + 7
f(-2) = 9(-2) + 7 = -18 + 7 = -11

(idk if you should have it as a decimal or a fraction)
x = -1
f(x) = 9x + 7
f(-1) = 9(-1) + 7 = -9 + 7 = -2


x = 0
f(x) = 9x + 7
f(0) = 9(0) + 7 = 7


x = 1
f(x) = 9x + 7
f(1) = 9(1) + 7 = 9 + 7 = 16


x = 2
f(x) = 9x + 7
f(2) = 9(2) + 7 = 18 + 7 = 25


You need to determine the solution of f(x) = g(x)
Since you know f(x) = 9x + 7 and
, you can plug in (9x + 7) for f(x), and (
) into g(x)
f(x) = g(x)
You can plug in each value of x into the equation
Your answer is x = 2 because when you plug in 2 for x in the equation, you get 25 = 25
