Answer:
A. (–8, 2)
Step-by-step explanation:
(1) y = ½x + 6
(2) y = -¾x – 4 Set (1) = (2)
½x + 6 = -¾x – 4 Multiply each side by 4
2x + 24 = -3x – 16 Add 16 to each side
2x + 40 = -3x Subtract 2x from each side
40 = -5x Divide each side by -5
(3) x = -8 Substitute (2) into (1)
y = ½(-8) +6
= -4 + 6
= 2
The solution to the system of equations is (-8 ,2).
You can see the graphs of the two functions in the figure below. The two lines intersect at (-8, 2).
Check:
2 = ½(-8) + 6 2 = -¾(-8) - 4
2 = -4 +6 2 = 6 - 4
2 = 2 2 = 2
Answer:if this helps it’s -3/2 and the slope is 8 :) C is the best answer!

Step-by-step explanation:
y-4=6
+4. +4
y=10
Answer:
-8
Step-by-step explanation:
when you substitute -8 for b it is -4(-8)+3=35
-4(-8) is 32 and 32+3=35
Boom.
also btw need help give brainliest
Answer:
20+56 or basically 76
Step-by-step explanation:
Just multiply -8 to -2.5 and -7.
