Answer:
The ordered pair is not a solution of the system D
explanation:
A.
y < -3
y ≤ 2/3x - 4
B.
y > -3
y ≥ 2/3x - 4
C.
y < -3
y ≥ 2/3x - 4
D.
y > -2
y ≤ 2/3x - 4
we know that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)
Verify each case
Case A) we have
----> inequality A
----> inequality B
Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results
Inequality A
----> is not true
therefore
The ordered pair is not a solution of the system A
Case B) we have
----> inequality A
----> inequality B
Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results
Inequality A
----> is true
Inequality B
----> is true
therefore
The ordered pair is a solution of the system B
Case C) we have
----> inequality A
----> inequality B
Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results
Inequality A
----> is not true
therefore
The ordered pair is not a solution of the system C
Case D) we have
y > -2 ----> inequality A
----> inequality B
Substitute the value of x and y of the point (3,-2) in both inequalities and then compare the results
Inequality A
----> is not true
therefore
The ordered pair is not a solution of the system D
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
Answer:
Step-by-step explanation:
-30n - 65 + 2 - 43
-30n - 63 - 43
-30n - 106
Answer:
If it looks like this then this is the answer but other wise say it more specific. 12/3=4 3/5=0.6....4/0.6=6.67
