Answer:
578.50
Step-by-step explanation:
The worker worked 40 hours at 13 dollars
40 * 13 =520
Then they worked 3 hours at 13(1.5) or 19.50
3*19.50 =58.5
The total amount of money earned is regular time plus overtime
520 + 58.5 =578.50
Answer:
x=1
Step-by-step explanation:
5x+9 - x= 13
Combine like terms
4x +9 = 13
Subtract 9 from each side
4x+9-9 = 13-9
4x = 4
Divide each side by 4
4x/4 = 4/4
x=1
Answer:
f(g(x)) = -9(sqrt(x + 1) ) + 9
-36
Step-by-step explanation:
This is easier to see if you use the expanded notation.
f(g(x)) = ?
But what that means is that the left most function is f(x) and where every you see an x, you put in a g(x) like so
f(g(x)) = -9(g(x)) + 9 Now substitute the right side of g(x) into the equation for f(x)
f(g(x)) = -9(sqrt(x + 1) ) + 9
Edit to get the numerical answer.
This should be your answer or the expression that will give you the answer.
f(g(24)) = -9(sqrt(24+1) ) + 9
f(g(24)) = -9sqrt(25) +9
f(g(24)) = - 9*5 + 9
f(g(24)) = - 45 + 9
f(g(24)) = - 36
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
