Answer:
where i^2 = -1 (minus one)
So, i^2 = -1
i^4 = (i^2)^2 = (-1)^2 = -1 X-1 = 1
like ;
i^32 = (i^2)^16 = (-1)^16 = -1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X-1 X -1 X
= 1

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -7x + 6
y = -10x
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -10x = -7x + 6
- Add 10x to both sides: 0 = 3x + 6
- Isolate <em>x</em> term: -6 = 3x
- Isolate <em>x</em>: -2 = x
- Rewrite: x = -2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -10x
- Substitute in <em>x</em>: y = -10(-2)
- Multiply: y = 20
Answer:
y= 2/5-1
Step-by-step explanation:
You get the 2/5 because you go 2 to the right and go 5 up, the -1 is because the x-int is at -1.

Answer: C
Step-by-step explanation:
When you are finding the area, the formula is A= Pi R^2.
The radius is half of the diameter. To get a diameter of 6, you have to multiply 3 by 2.
