If I were solving this equation, I would put x^2-20x+(100)=(10). Since this is in standard form, you could change this into vertex form by making the equation y=(x-10)^2 -10.
Answer:
A
Step-by-step explanation:
f(-3) = 2^-3
to get rid of a negative in an exponent, move the whole thing to the denominator.
1/(2^3)
2^3 = 2×2×2
1/(2×2×2)
1/8
Isn’t it choice B …….…………
A+(-1.3)=-4.5
Add 1.3 to both sides of the equation
a=-3.2
Yes, they intersect at roughly (4.2,5.2).
