<span>f(x) =-(x+9)(x-21)
Manipulating algebrically,
We get,
</span>f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
X+10+3x+18=180 is the first part
4x+28=180
4x=152
x=38
I believe the answer is 2 because 1/2 x 4 = 4/2 =2
Answer:
Step-by-step explanation:
f(x)=4x+5
g(x)=6x+4,
first: (f*g)=(4x+5) (6x+4)=24x²+46x+20
next:(f*g)(0)=((g*f)=24x²+46x+20=20
Answer:
c = -25
Step-by-step explanation:
Multiply the denominator by -7 on both sides, you would then get the equation c + 32 = 7 in which the -7 on the left side cancels out. Subtract 32 on both sides to get the c value which is -25.
