4*10^6 = 4,000,000 1*10^4 = 10,000 4,000,000 x 10,000 = 40,000,000,000 ANSWER: 40,000,000,000
The answer is 7, because you multiply it by 6.
You have the correct axis of symmetry value. Nice work.
Plug that x value into the equation to get...
y = -2x^2 - 12x - 10
y = -2*(-3)^2 - 12*(-3) - 10 <<-- replace every x with -3; then use PEMDAS
y = -2*(9) - 12*(-3) - 10
y = -18 + 36 - 10
y = 18 - 10
y = 8
The vertex is the ordered pair (-3, 8)
Note: the axis of symmetry is the vertical line through the vertex
Answer:
10
Step-by-step explanation:
It’s the first one! The table shows X going up and Y going down, so the slope would be negative!
