Answer:
Step-by-step explanation:
3z + 9 + 142 = 4z + 5
3z + 151 = 4z + 5
-z + 151 = 5
-z = -146
z = 146
answer is B
exactly one solution
Answer:
8, 32, and 40
Step-by-step explanation:
1+4+5=10
80/10=8
8*1=8
8*4=32
8*5=40
Answer:
C) 3
Step-by-step explanation:
2x-y=3
-4x+2y=-6
4x+3y=11
-4x+2y=-6
4x+3y=11
5y=5
<u>y=1</u>
2x-y=3
2x-1=3
2x=4
<u>x=2</u>
2+1=<em><u>3</u></em>
Plug them into point-slope form.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Plug in what we know:
y - 4 = -5(x + 2)
So one of our answers is C.
Now distribute -5 into the parenthesis:
y - 4 = -5x - 10
Add 4 to both sides:
y = -5x - 6
Add 5x to both sides:
5x + y = -6
So the other answer is B.
