Answer:
Step-by-step explanation:
g(-1) = 4(-1) - 3 = -4 -3 = -7
f(-7) = (-7)^2 + 3 = 49 + 3 = 52
Answer is D
Answer:
Step-by-step explanation:
d) (-2 +4i) -( 3 + 9i) = -2 + 4i - 3 - 9i
= -2 - 3 + 4i - 9i
= -5 - 5i
e)3i(6 - 5i) = 3i *6 - 5i * 3i
= 18i - 15*i² {i² = -1}
= 18i -15*(-1)
= 18i + 15
= 15 + 18i
f) (-3 + 7i)(1 - 2i) = (-3)*1 - 2i * (-3) + 7i *1 - 2i* 7i
= -3 + 6i + 7i - 14i²
= -3 + 6i + 7i - 14*(-1)
= -3 + 6i+ 7i + 14
= 11 + 13i
4 year college Tuition: $28,800.00
Money Saved since Sarah was born: $21,600.00

That's true they are proportional
Answer:
P = 12x - 9
Step-by-step explanation:
To find the perimeter of the triangle, we just add all of the sides.
The formula is:
P = a + b + c
Given:
a = 5x - 6
b = 4x - 3
c = 3x
Work:
P = a + b + c
P = 5x - 6 + 4x - 3 + 3x
P = 12x - 9
