Answer: b/a = -8
Step-by-step explanation:
When we have a quadratic equation:
y = a*x^2 + b*x + c.
The vertex of this function (and the axis of symetry) is located at:
x = -b/2a
Now, we know that the axis of symmetry is at x = 4.
then we have:
4 = -b/2a
And we want to find b/a.
Then we start with:
-b/2a = 4.
first we multiply by 2 in each side:
2*(-b/2a) = -b/a = 2*4 = 8.
now we multiply by -1 in each side:
-1*(-b/a) = b/a = -1*8.
Then we have: b/a = -8
Answer:
B
Step-by-step explanation:
3 in the expression is part of -3x called the coefficient of the variable. See the definitions below to distinguish the difference between each term:
A.
variable - an unknown value represented with a letter
B.
coefficient - a number written with a variable denoting how many
C.
constant - a number without a variable denoting how much
D.
exponent - a number written on a base denoting how many times to multiply the base by itself
