Answer:
Step-by-step explanation:
y-(-2) = 1/2(x-12)
y+2 = 1/2x - 6
y = 1/2x -8
y = mx +b
5/7. Use rise over run it helps
Answer:
4-3i is the answer.......
Explanation
<u>Product</u>
(2-i)(1+2i) = 2+4i-i-2i²
= 2+4i-i+2
= 4+3i
conjugate of 4+3i is 4-3i
We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓
