Answer:
f(x) = -0.5x + 3.5
Step-by-step explanation:
f(x) = mx + b
f(-1) = -m + b = 4 ...(1)
f(5) = 5m + b = 1 ...(2)
(1)-(2): -6m = 3 m = -1/2 (-0.5)
b = 4 + (-1/2) = 3.5
Equation: f(x) = -0.5x + 3.5
Answer:
x = -13/4
Step-by-step explanation:
5 - (4x + 7) - 4 = 7
Distribute the minus sign
5 - 4x -7 - 4 = 7
Combine like terms
-4x-6 = 7
Add 6 to each side
-4x-6+6 = 7+6
-4x= 13
Divide by -4
-4x/-4 = 13/-4
x = -13/4
You mean months?
Anyhoo, there are 12 months in a single year. Or you can say, 12x. Plug in 4356 for x and solve.
12*4356
=52272 months
Answer:
Statement B is true because after -ve 13 come out it becomes +ve
Answer:
(-1,3)
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
1 = (2-3)/(-2-x)
Multiply each side by (-2-x)
(-2-x) = -1
Multiply by -1
2+x = 1
Subtract 2 from each side
2+x-2 = 1-2
x = -1
