Answer:
C
Step-by-step explanation:
You can use the formula y=mx+b
f(x) is the same as y
m=slope
b=y intercept
We know that the slope is -2 so which answer has -2 as b? (Which one has a -2 before the x?)
Y Intercept is where the line crosses though the y axis. The point of the y intercept will ALWAYS have 0 as x. So (0,4) is the y intercept. You could also say 4 is the y intercept. Which one has 4 as b? (Which one says +4 after -2x)
The only answer that matches is C.
I hope thay made sense.
Answer:
91
Step-by-step explanation:
Let
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
Total = 182
x + x + 1 + x + 2 + x + 3 = 182
4x + 6 = 182
Subtract 6 from both sides
4x + 6 - 6 = 182 - 6
4x = 176
Divide both sides by 4
x = 176 / 4
= 44
x = 44
x = 44
x+1 = 44 + 1 = 45
x+2 = 44 + 2 = 46
x+3 = 44 + 3 = 47
Sum of the two middle numbers = 45 + 46
= 91
Answer:
y = 4x - 7
Step-by-step explanation:
m = 4
y - y1 = m(x - x1)
y - 5 = 4(x - 3)
y - 5 = 4x - 12
y = 4x - 7
I dont know the answer becouse im not there but i can show you how to get the answer..
you know the rulers the are half way cut?use that and measure each angle
(i hope i helped!)
