The graph is money earned vs hours worked. If he works 1 hour, he earns $10.
If he works 0 hours (doesn't work), he earns $0.
A.
To find the mean of a data set, you have to add all of the numbers and divide by the number of data.
So
50 + 54 + 62 + 48 + 49 + 52
To get 315.
315 divided by 6 is 52.5
So the mean of he data set is 52.5
Hope this helps :)
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
The difference (the answer of a subtraction problem) is:
2/7 - 2/5 --> 10/35 - 14/35 = -4/35
The answer sum (the answer of an addition problem) is:
2/7 + 2/5 --> 10/35 + 14/35 = 24/35

Answer:
<span>−84</span>
Explanation:
Let x be the unknown number.
From the queston we can form the equation
<span><span>x<span>(−7)</span></span>−2=10</span>
Move <span>−2</span> to the right hand side
<span><span><span>x<span>(−7)</span></span>=10+2</span><span><span>x<span>(−7)</span></span>=12</span></span>
Multiply both sides by <span>−7</span> to get the unkonwn no.
<span><span><span>−7</span>⋅<span>x<span>(−7)</span></span>=12⋅<span>(−7)</span></span><span>
x=−84</span></span>
Hope this helps
