Answer:
No
There are infinitely many solutions to the system.
{36x+21y=24312x+7y=81
Multiply the second equation by 3.
3(12x+7y36x+21y=81)=243
Subtract this new equation from the first equation.
36x+21y−(36x+21y0+0=243=243)=0 true
Answer:
The value of f[g(2)] is 71.
Step-by-step explanation:
We need to find f[g(2)].
The first step is finding f[g(x)]
We have that:
To find f[g(x)], the first step is replacing each x is f by g(x). So
Now we replace x by 2
The value of f[g(2)] is 71.
3z < 30 - 6
3z < 24
z< 24/3
z< 8
answer is z < 8
Answer:
- equation: 1368 = 380 +52x
- labor hours: 19
Step-by-step explanation:
The desired equation will relate labor cost, parts cost, and total cost.
<h3>A.</h3>
The total cost is the sum of the parts cost and the product of labor hours and labor rate. We're told to use x to represent labor hours.
total cost = part cost + (labor rate)(labor hours)
1368 = 380 + 52x
__
<h3>B.</h3>
This equation can be solved in 2 steps:
988 = 52x . . . . . . . step 1, subtract 380 from both sides
19 = x . . . . . . . . . . step 2, divide both sides by the coefficient of x
The number of labor hours was 19.
