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
This differs on what number you want to talk about. 1 is the hundreds, 8 is the tenths, 7 is the ones.
Step-by-step explanation:
2x-3y= -14
5x+9y= -2
multiply the first one by 5 and the second one by -2 to get equal and opposite value of x.
➡️when you multiply,it will be
10x-15y= -70
-10x-18y= 4
cancel out each x value,then you get
-15y-18y= -70+4
-33y= -66, divide each side by -33 to get the value of y
⚪️y= 2
➡️substitute the value of y in the equation of (2x-3y= -14) to find the value of x
2x-3(2)= -14
2x-6= -14
2x= -14+6
2x= -8 divide both side by 2
⚪️x= -4
so the answer is (-4,2)
Answer:
$21.59
Step-by-step explanation:
The original hourly rate was x.
She raised it 6%. The raise is 6% of x, or 0.06x.
The new rate is x + 0.06x or 1.06x.
The new rate is $22.89.
1.06x = 22.89
Divide both sides by 1.06.
x = 21.59
