Answer: The mechanic worked for 4.25 hours for the fourth customer.
First find out the slope.
Y^2-y^1/x^2-x^1
210-90/3-1=60
Slope: 60
Then find out what the y-intercept is by plugging in values we know into y=mx+b
90=60(1)+b
30=b
Y=60x+30
Substitute the y with 285 to find out the x (hours)
285=60x+30
4.25=x
1 to the 28 power? idk if that's right. I did exactly what you said in the calculator and that's what the result was.. sorry if im wrong:/

Answer:
51
Step-by-step explanation:
The rule gives the sequence ...
75, 69, 63, 57, 51, 45, ...
The 5th number in the sequence is 51.
__
<em>Alternate solution</em>
The equation for the general term of an arithmetic sequence is ...
an = a1 +d(n -1) . . . . . for first term a1 and common difference d
Your sequence has first term 75 and common difference -6, so the equation is ...
an = 75 -6(n -1)
Then for n=5, the term is ...
a5 = 75 -6(5 -4) = 75 -24 = 51
The 5th term is 51.
Answer:
Answer: B. (10x60) + (4x3)
Step-by-step explanation:
When summing, we can set it up as a proportion. But first, we take the 2 numbers apart from each other so we can set this up, now its this; 10/60
4/3
You can see because if we add 60 +4 it gives us the original, and same with 10 + 3.
