Answer: 0
Step-by-step explanation: you just have to divide a little bit then you just multiply.
Answer:
I would say that the answer is A. -4x + 9y = 11
Hope it helps, sry if it's wrong. It shouldn't be though.
Slope = (5+7)/(1-4) = 12/-3 = -4
slope = -4
y = mx + b
-7 = -4(4) + b
-7 = -16 + b
b = 9
equation
y = -4x + 9
Answer:
x = -2.585
Step-by-step explanation:
You will have to plug this into your graphing calculator.
In y=, type 5(1/2)^x in the Y1 and type 30 in Y2.
When you hit 2nd trace and hit find intersections, you will get (-2.585, 30).
The answer is x = -2.585
