Answer:
$39.10
Step-by-step explanation:
$40 * 1.15 = $46
$46 * 0.85 = $39.10
Answer:
y = -2x - 8
Step-by-step explanation:
<u>Use the point slope form: (y - y1) = m(x - x1)</u>
(y - (-4)) = -2(x - (-2))
y + 4 = -2(x + 2)
y + 4 - 4 = -2x - 4 - 4
y = -2x - 8
Answer: y = -2x - 8
Answer:
5625in²
Step-by-step explanation:
Area of the plate = πr²
625π = πr²
625 = r²
r = √625
r = 25in
If the radius of the plate is tripled, then the new radius will be 3(25) = 75in
New Area = π(75)²
New Area = 5625π in²
If the radius is tripled, the new area of the plate is 5625in²
x = 20 is the answer.
<u>Step-by-step explanation:</u>
When a parallel lines cut by a transversal, then the alternate exterior angles are congruent.
So the given 2 angles add up to 180 degrees.
5x+ 9 + 3x+ 11 = 180
8x + 20 = 180
8x = 180 - 20 = 160
x = 160/8 = 20
The answer are both:
x=2+4i,2-4i
