4(8) - 3 • 81
The first one
12 would be the unit rate you mulitply 3 × 4
Answer:
Step-by-step explanation:
No solutions....means the lines are parallel...means ur 2 equations have to have the same slope but different y intercepts
y = 2x + 4 and y = 2x + 3
========================
Infinite solutions...means u have the same line
y = 2x + 4 and 2y = 4x + 8....notice how if u reduce the 2nd one by dividing everything by 2 u get y = 2x + 4...same line
========================
1 solution....means ur equations will have different slopes and different y intercepts.
y = 2x + 4 and y = 4x + 2
now, u can pick which one u want :)
125 i believe i’m not sure
Answer:
8. 1483.33
9. 21 months
Step-by-step explanation:
8. Morgan's income after taxes is 55000/12 = 4583.33 per month. The amount available after expenses is 4583.33 -3100.00 = 1483.33 per month.
Morgan is able to put $1483.33 per month into savings.
__
9. If Morgan is able to save $1483.33 per month, it will take her ...
$30,000/$1483.33 ≈ 20.2
months to save $30,000. After 20 months, she won't have quite enough, so it will take her one more month to save the desired amount.
It will take Morgan about 21 months to save $30,000.
_
If you like, you can write an equation for "m", the number of months it will take Morgan to save 30,000:
1483.33×m = 30,000
m = 30,000/1483.33 ≈ 20.2 . . . . . . divide by the coefficient of m
