Step-by-step explanation:
it is totally simple : you need to put the x-value into every place of the x-variable, and then we calculate.
and then the same for the next x-value. and the next. ...
-2
-2×-2 + 9 = 4 + 9 = 13
0
-2×0 + 9 = 0 + 9 = 9
2
-2×2 + 9 = -4 + 9 = 5
4
-2×4 + 9 = -8 + 9 = 1
Answer:

2) ?
3) 2(3^3) + 11
4) 16^2 - 79
Step-by-step explanation:
1) 101 = 100 +1 = 10^2 +1
2) ?
3) 173 = 81+81+11 = 3^3+3^3+11 = 2(3^3) +11
4) 177=256-79 = 16^2 -79

Answer:
1/625
Step-by-step explanation:
When you multiply, you add the exponents. You now have . This is equivalent to which equals 1/625.
If you divide the wages by the number of hours you always get $56.25 so he gets $56.25 per hour.
Answer:
x = 9
Step-by-step explanation:
This shape is a 30-60-90 triangle, which means that the angles of the triangle are each 30°, 60° and 90°. Given that the measures of the angles of the triangle are known, as well as one side, we can find the measures of all the other sides (example attached). A 30-60-90 triangle is special because of the relationship of its sides. The hypotenuse (directly across from the 90° angle) is equal to twice the length (2x) of the shorter leg, in this case labeled 'x' and directly across from the 30° angle. The longer leg, across from the 60° angle, is equal to multiplying the shorter leg (x) by √3 or x√3.
Since the measure of the hypotenuse is given at 18, we can set the expression of that side equal to 18 and solve for x:
2x = 18 or x = 9
