Answer:
The answer to your question is
x = -2 and y = 10 or x = 10 and y = -2
Step-by-step explanation:
x + y = 8 (1) from (1) x = 8 - y
xy = - 20 (2)
Solve them by substitution
(8 - y) y = - 20
8y - y² = -20
y² - 8y - 20 = 0
( y - 10) (y + 2) = 0
y - 10 = 0 and y + 2 = 0
<u> y1 = 10 </u> <u>y2 = -2</u>
x1 = 8 - 10 x2 = 8 - -2
<u>x1 = -2</u> <u> x2 = 10</u>
Answer:
L = 9
Step-by-step explanation:
Assuming you are trying to find L
P = 2L + 2W
P = 32
32 = 2L + 2W
W = 7
32 = 2L + (2 × 7)
32 = 2L + 14
2L = 32 - 14
2L = 18
L = 9
Answer:
Hannah
Step-by-step explanation:
She spent more time on the interviews thus got to less
Answer: (A) 19.3%
<u>Step-by-step explanation:</u>

Vodka + Vermouth + Olive = Total Cost
$2.59 + $0.12 + $0.15 = $2.86

The horizontal distance is given by the formula:
tan θ=opposite/adjacent
where:
θ=21
opposite=2000 ft
adjacent=a
thus calculating for a we get:
tan 21=2000/a
thus
a=2000/tan 21
a=5210.18 ft
Answer: 5210.18 ft
