Answer:
-8
Step-by-step explanation:
All you have to do to solve this equation is plug "-3" into the equation where you see "x"

#21)
<span>Using Pythagorean Theorem a^2 + b^2 = c^2
so
</span>a^2 = c^2 - b^2
x^2 = 42^2 - 38^2
x^2 = 1764 - 1444
x^2 = 320
x =√320
x = √(64 * 5)
x = 8√5
Answer: 3 + 7i
Step-by-step explanation:
Equation expanded: 12 + 5i - 9 + 2i // now simplfy
12 - 9 = 3
5i + 2i = 7i
// together, we get
3 + 7i

Answer:
(1,6) , (2,7) , (3,8) , (4,9) , (5,10)
Step-by-step explanation:
Given equation: y = x + 5
when x = 1, y = 1 + 5 = 6
(1,6)
when x = 2, y = 7
(2,7)
when x = 3 , y = 8
(3,8)
when x = 4 , y = 9
(4,9)
when x = 5 , y = 10
(5,10)
