Answer:
-62
Step-by-step explanation:
X=2 Y=-1 plug them into the equation
-3(2)^2 + 2(-1)^2 + 5(2)(-1) -2(-1) + 5(2)^2 -3(-1)^2
36+4-10+2+100+9
40-10+2+100+9
30+2+100+9
132+9
141
Answer:
D, $18,000.00
Step-by-step explanation:
Club A
$3 x is donated where x is the number of donations
Club B
$1.25x is donated where x is the number of donations
The total of donations is 25500.00
Add the donations times the dollar amount for Club A and Club B and you get the total amount donated
$3x +$1.25x = 25500.00
Combine like terms
4.25x = 25500.00
Divide by 4.25 on each side
4.25/4.25x = 25500.00/4.25
x =6000
There were 6000 donations
We want to find Club A donation amount
$3 x is the amount donated
3*6000 = 18000
X= 180 - 157
= 23
Therefore, X is 23 degrees. A straight line has an angle of 180 degrees, so subtracting the given angle would give you X.
