Answer:
12
Step-by-step explanation:
3√1000 = 10
because 10 • 10 • 10 = 1000
3√8 = 2
because 2 • 2 • 2 = 8
10+2 = 12
It's not plus or minus because it's a cube root rather than a square root.
First isolate y by adding x to both sides in y-x=3 and getting y=x+3
Step 1: substitute x+3 for y in 3y=x+6 to get 3(x+3)=x+6
Step 2: distribute 3x+9=x+6
Step 3: subtract like terms 2x=-3
Step 4: divide x=-3/2
substitute -3/2 for x in y=x+3 to get
y=-3/2+3
y=3/2
answer: y=3/2 x=-3/2
Slope of y=1-2x is -2
Using point intercept form:
y-1=-2(x-3)
y-1=-2x+6
y=-2x+7
