Wouldn’t it be 180° I’m not sure but I’m pretty sure that it’s a reflection
Answer:
x=-1
Step-by-step explanation:
7x + 8 − 3x = −6 + 10
4x+8=4
4x=4-8
4x=-4
x=-4/4
x=-1

Answer:
<em>c. y = 1.25</em>
Step-by-step explanation:
The equation for direct variation is
y = kx,
where k is the constant of proportionality.
We can use the given values of x and y to find k for this case.
y = kx
-10 = k * 40
k = -10/40
k = -0.25
The equation for this case is
y = -0.25x
Now we let x = -5 and solve for y.
y = -0.25x
y = -0.25(-5)
y = 1.25
Answer: c. y = 1.25
Answer:
a. Y=-2x+4
Step-by-step explanation:
6x+3y-9=3
+9 +9
6x+3y=12
-6x -6x
3y=-6x+12
/3 /3 /3
y=-2x+4
