A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
4m - 7n = 10
2m + 2n = 4 - multiply everything by -1.
4m - 7n = 10
-2m - 2n = -4 Add the 2 equations
(4m - 7n = 10)
+(-2m - 2n = -4)
-------------------------
2m - 9 n = 6.
The value of 2m - 9n would be 6.
Answer:
B.
Step-by-step explanation:
<span>Let g(x) = f(x) - 4
g(x) is a translation of f(x) down 4 units so (-3, 1) will be the new point
find g(-3)
g(-3) = f(-3) - 4
= 5 - 4
= 1
