45 = 90% * x
45 = .90x
45/.90 = x
x = 50
45 is 90% of 50
Answer:
all real values of x where x < -1
Step-by-step explanation:
See attached graph.
The y-intercept is 2 and the Slope is 2/4 but if you simplify that, it will be 1/2.
Answer:
y = -11x + 9
Step-by-step explanation:
m = -11
x = -1
y = 20
Plug those values into the equation to find b: y = mx + b
20 = (-11)(-1) + b
---> b = 9
Plus m = -11 and b = 9 into y = mx + b
---> y = -11x + 9
