Get x on its own side
7+x-15=2 2/3
+15 +15
7+x=17 2/3
-7 -7
x= 10 2/3
Hope I helped
Using translation concepts, the graph of f(x) is given at the end of the answer.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The parent absolute value function is given by:
f(x) = |x|
Which has the graph in the format of a V centered at the origin.
The translated function is given by:
g(x) = -1/2|x + 4| + 2.
The translations are as follows:
- Reflection over the x-axis, due to the multiplication by the negative number, thus the V is pointing down now.
- Vertical compression by a factor of 2, due to the division by 2.
- Shift left of 4 units, as x -> x + 4.
- Shift up of 2 units, as y -> y + 2.
Due to the last two translations, the graph is now centered at (-4,2) and is given at the end of the answer.

Answer:
$647.99
Step-by-step explanation:
Divide the tax rate (9.750%) by 100 to get a decimal rate of 0.09750.
Add 1 to the decimal rate to get 1.09750.
Divide that tax-included price ($647.99) by 1.09750 price to get a pretax price of $590.42.
Subtract the pretax price from $647.99 to get the sales tax amount of $57.57.
Answer:
87 minutes
Step-by-step explanation:
Let the total number of minutes = m
Our equation is given as:
$20.21 = $14.99 + 0.06m
20.21 = 14.99 + 0.06m
Collect like terms
0.06m= 20.21 - 14.99
0.06m = 5.22
m = 5.22/0.06
m = 87
Therefore, the total number rod minutes used is 87 minutes
