Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.
1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81
2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...
Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.
Consider an absolute value inequality.
For example, 3≤|x-7|
this means that x-7 can be
i) 3, 3.4, 5, 7.5 etc
or ii) -3, -3.2, -4.7 etc since these values in abs value all are ≥3
thus the set of all values in i) is represented by x-7≥3, which means x≥10
and the set of all values in ii) is x-7≤-3, which means x≤4.
Thus, the compound inequality is : x≥10 OR x≤4
an absolute inequality corresponding to this compound inequality is 3≤|x-7|
I think that the answer is B.0.0000000861
The answer for finding the slope is -1/2
