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)
9m
It said the sides are 25m (x2) and 9m(x2). The width of a rectangle are shorter than the length so 9m.
This is a basic algebraic fraction question
Step 1: Factor n2-9
Step 2: Rewrite the second fraction
Step 3: Write all the numerators under the least common denominator
Step 4: Expand bracket
Step 5: Collect like terms
Answer: D 14, 15, 15, 16, 17, 18, 30
Step-by-step explanation: it’s D because it has the highest point on the graph soo it’s the highest skew
Answer:
Step-by-step explanation:
a) 60 = 50x
x = 60 / 50 = 1.20
1.20(100) = 120%
b 50 = 60x
x = 50/60 = 0.83333....
0.83333(100) = 83.333... % or 83⅓%
