8+2x=6x
subtract -2x on both sides
8=4x
Divide by 4 on both sides
2=x
all you need is the story :)
Answer:
$4.41
Step-by-step explanation:
10+12+15+18+20=75
75/x=17
17x=75
X=4.41
Answer:
y = ± sqrt(x+7)
Step-by-step explanation:
y = x^2 -7 solve for 'x' .... add 7 to both sides
y+7 = x^2 sqrt both sides
+- sqrt(y+7) = x switch 'x' and 'y'
y = +- sqrt(x+7)
Answer:

Answer:
x-intercept : 0.5; y-intercept : 1
Step-by-step explanation:
y intercept when x = 0, so x = 0, y = 1
x intercept when y = 0 so y = 0, x = 0.5
Answer
x-intercept : 0.5; y-intercept : 1
