Answer: 7x + 9w if you are just simplifying
Step-by-step explanation:
Set <span>C(h)=75h+50 = to 650 and solve for h, the number of hours the repair required:
75h = 600 Dividing both sides by 75,
h = 600/75 = 8 hours (answer)
Are you sure you wanted to write "</span><span>Mr sellners car was repaired and repaired"? </span>
Use the Law of Sines:
600 a
---------- = ---------- where 94 came from subtracting (11 + 75) from 180.
sin 11 sin 94
Solve this for side a.
30% of his questions was 6 questions.
Translate that to a math equation where q= total number of questions.
30% x q = 6
.3 x q = 6
q= 6/.3
q= 20
There were 20 questions in the test.
And 30% of 20 is 6 so that is the correct answer.
Hope this helps :)
Answer:
2.C
3.B
4.B
5.D
Step-by-step explanation:
2. the y intercept in this equation is the c value, which is 1 so the answer is c
3. The vertex of this function would be (9, -5) and the axis of symmetry is the first value so its 9, B
4. Not that hard, tip is to just distribute in all the answers and see which one gives you the original equation, it is B
5. You solve the original equation by completing the square, if you don't know how to do that look it up. Answer is D
