Answer:
The answer to your question is below
Step-by-step explanation:
2. 
Just find the prime factors of 128 and simplify
3.- 
Get the square roots and simplify
3i + 4i
7i
4.- None of the choices is equal to one, because the exponents are pair.
5.- 1/3x² + 10 = 7
1/3x² = 7 - 10
1/3x² = -3
x² = -3(3)
x² = -9
x = ±3i
Answer:
34.45
Step-by-step explanation:
11÷2 = 5.5
so 5.5x5.30 = 29.15 + 5.30 = 34.45
5 x 3/4 = 15/4
15/4 = 3 3/4
The answer is 96.
24 divided by 4 is 6.
4 times 24 equals 96. there is 4 quarts in a gallon.
The points of intersection are at (3, 6) and (-1, -2).
Since both of these equations have y isolated, we can set them equal to each other:
2x=x²-3
We want all of the variables on one side, so subtract 2x:
2x-2x = x²-3-2x
0=x²-3-2x
Write the quadratic in standard form:
0=x²-2x-3
This is easily factorable, as there are factors of -3 that will sum to -2. -3(1)=-3 and -3+1=-2:
0=(x-3)(x+1)
Using the zero product property we know that either x-3=0 or x+1=0; therefore x=3 or x=-1.
Substituting this into the first equation (it is simpler):
y=2(3) = 6
y=2(-1)=-2
Therefore the coordinates are (3, 6) and (-1, -2).
