Step-by-step explanation:
-2|5x + 3| >= 4
|5x + 3| <= -2
Since absolute value is never negative, there are no real values for x.
Answer:
he must have 200000 dollars to earn 6000 in commission
Answer:
The equation for the amount of dollars pledged in total is f(M) = 2.00M + 7.25, and the amount for just Kiara is f(M) = 0.25M + 5.25
Step-by-step explanation:
The amount they pledge up front is a constant and therefore need to be added to the end of the equation. The amount per mile should be a variable amount. This gets multiplied by the M variable. So we start with the Kiara amount.
0.25 per mile = 0.25M
5.25 pledged = 5.25
Now put them together to get f(M) = 0.25M + 5.25
Do the same with Mark.
1.75 per mile = 1.75M
2.00 pledged = 2.00
Now put them together to get f(M) = 1.75M + 2.00
To get the final total, we add both equations together.
f(M) = 0.25M + 5.25 + 1.75M + 2.00
f(M) = 2.00M + 7.25
Answer:
m = 3; b = -12
Step-by-step explanation:
In order to answer the question definitively, we must assume you intend for the equation to be an identity.
6(2x -5) -(mx +2) = 9x +b
12x -10 -mx -2 = 9x +b
Equating x terms:
12x -mx = 9x
12 -m = 9 . . . . . . divide by x; next, add m-9
12 -9 = m = 3
Equating constant terms:
-10 -2 = b
-12 = b
