Answer:
number (c)
Step-by-step explanation:
I am not sure about this
80 weeks
1,200+40x=400+50x
800+40x=50x
800=10x
x=80
-5 to the 4th power in expanded form would be -5 x -5 x -5 x -5. This is equal to positive 625.
Answer! :
y = -2x + 5
Step by Step! :
slope intercept form:
y = mx + b
m being slope, b being the y intercept.
To find the slope, use this equation:
y^2 - y^1 / x^2 - x^1
Plug in your points.
(-1) - (7) / (3) - (-1)
-8 / 4
-2 is your slope! (y = -2x + b)
To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)
-1 = -2(3) + b
-1 = -6 + b
5 = b
Your new equation is...
y = -2x + 5
