Answer:
-35a
Step-by-step explanation:
Here, you just distribute: -7 * 5a
= -35a
kx-4=9
Move -4 to the other side. Sign changes from -4 to +4
kx-4+4=9+4
kx=13
Divide by k for kx and 13
Cross out k and k = 1.
x=13/k
Answer: x=13/k
Answer:
C and B.
Step-by-step explanation:
f(x) = 4 - x^2.
The degree of f(x) is 2, which means it is a quadratic graph. The coefficient of x^2 is negative, which means the curve is pointing downwards. The only curve that satisfies this is Graph C.
f(x) = 2^x + 5.
Notice that 2^x is positive for all real values of x. Therefore the answer is Graph B.
