<u>Step by Step Explanation:</u>
16. x - 4 = 4
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:
x - 4 (+4) = 4 (+4)
x = 4 + 4
x = 8
17. a/4 = 4
Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:
(a/4)(4) = (4)(4)
a = (4)(4)
a = 16
18. y * 20 = 30
Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.
(y *20)/20 = (30)/20
y = 30/20
y = 3/2 or 1.5
19. x/5 = 20
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides
(x/5)(5) = (20)(5)
x = (20)(5)
x = 100

Answer:
y = 1/6x + 7/3
Step-by-step explanation:
(-2 ,2) and (-8, 1)
Slope=(1-2)/(-8- - 2) = (-1/-6) = 1/6
b = 2 - (1/6)(-2) = 2 - 2/6 = 2 - 1/3 = 7/3
Answer:
4×^2-4×-3=0factor(2×+1)
(2×-3)=0 2×+1=0 2+-3=0 2×=-1
2×=3 ×=-1/2 ×=3/2
×=1/2, 3/2
