Answer:
Step-by-step explanation:
1. f(-2) = 6 * 1/3^-2
f(-2) = 6 * 9
f(-2) = 54
2. y = -3 * 4^3
y = -3 x 64
y = -192
3. f(4) = 1/4 * 2^4
f(4) = 1/4 * 16
f(4) = 4
Let me know if I am right!
Answer:
Graph A.
because it bends at an angle and doesn't curve makes it a non-function
A)
The discriminant (radicand) is √(b^2-4ac), let us call this "d" for the discriminant.
If:
d<0, there are no real solutions (though there are two imaginary ones)
d=0, there is one real solution
d>0, there are two real solutions.
In this case, d=12^2-4(4)9
d=144-144
d=0
So there is one real solution.
B)
9x^2-30x+25=0
9x^2-15x-15x+25=0
3x(3x-5)-5(3x-5)=0
(3x-5)(3x-5)=0
(3x-5)^2=0
x=5/3
x=1 2/3
Answer:
your answer is CCCCCCC
Step-by-step explanation:
When you move a number to the opposite side of the equation, in this occasion it will be 23- it changes to the opposite value. So us 23 is a positive value you can move it and change it to a negative. Or in other words suntract -23 from all sides of the equation, which will be equal to:
y = 59 - 23
Y = 36
