9,899 = 206x
He divided by 206
He got 48.053 and rounded up to 49
My using the equation, we can see that he is correct.
Answer:
45
Step-by-step explanation:
Divide 30 by 10. You get 3. Take three and multiply it by 15. Your answer is 45.
Answer:
y = 1/2x + 1
Step-by-step explanation:
Step 1: Find slope
(1-0)/(0+2) = 1/2
Step 2: Write equation
y = 1/2x + 1
Answer:
(-7,4)
Step-by-step explanation:
goal: (y-k)^2=4p(x-h)
y^2-8y=4x+12 Rearranged and added 4x and 12 on both sides
y^2-8y+(-8/2)^2=4x+12+(-8/2)^2 complete square time (add same thing on both sides)
y^2-8y+(-4)^2=4x+12+(-4)^2 (simplify inside the squares)
(y-4)^2=4x+12+16 (now write the left hand side as a square)
(y-4)^2=4x+28
(y-4)^2=4(x+7) factored...
vertex is (-7,4)
