Step-by-step explanation:
17 * 50 = 850
850 - 25 = 825
So stephen worked 50 hours
Answer:
15) Quadratic Function : The 3x is squared
16) Linear Function : It is a straight line
17) Quadratic Function : The line is a U shape
18) Linear Function : There is one y value for every x value, and the points form a straight line
Step-by-step explanation:
Done
Short answer: C
Remark
Since b is all by itself in equation 2, Substitute it into equation 1.
2a + 3b = 5
b = a - 5 Put this result in equation 1. Be sure and use brackets.
2a + 3(a - 5) = 5 Remove the brackets.
2a + 3a - 15 = 5 Notice the -5 inside the brackets becomes - 15
Combine like terms on the left.
5a - 15 = 5 Add 15 to both sides
5a = 5 + 15
5a = 20 Divide by 5
a = 20/5
a = 4
So far, c is the only possible answer.
b = a - 5
b = 4 - 5
b = - 1
First, lets subtract the goal by 3, because she already did them.
15 - 3
12
Now, lets divide by one because that will leave you with the number of days
12/1
12
So, It will take her 12 days if she keeps up with her goal.
Hope this helps!
