The formula of a slope:
We have the points (1, k) and (-1, -4) and the slope m = 3/2. Substitute:
5) x^2+3x-1. when x <= -2
3f (-5)= 3 (5^2+3 (-5)-1)
= 75-45-3
=27
-2 <x <6
2 (2)^x-1
4f (2)= 4. (2 (2)^2-1)
=16
x>6
f (10)= (3x+6)/x+2
= 36/12
=3
3f (-5)+4f (2)-f (10)
= 27+16-3
=40. 40 is the final answer
Good luck; )
The answer is B. I hope this helps.
Answer:
Step-by-step explanation:
We want to find the difference:
We expand the parenthesis using the distributive property to get:
Regroup similar terms on the right:
Combine similar terms on the right:
Therefore the difference is x-2
Answer:
y-(-2)=-2(x-3)
Step-by-step explanation:
point-slope form:y-y1=m(x-x1)
y-(-2)=-2(x-3)
-2+2=0
-3+2=(-1)
y=-2(x-1)
-2*x=(-2x)
-2*-1=2
y=-2x+2
-2 is the slope
2 is the y-intercept
hope this helps :3
if it did pls mark brainliest
