Option A, because you split the (2x + 3) into 2x and 3.
Answer:
The equation will be:
C(g) = 15g + 62, if g > 2
ANSWER:
x° = 24°
y° = 72°
Analysis on picture hope it helps
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
Answer:
85.15
Step-by-step explanation:
79.95 x 0.065 = 5.197
79.95 + 5.197 = 85.15
