Answer:
2x-106
Step-by-step explanation:
-7(x+10)+9(x-4)
Expand parentheses:
-7x-70+9x-36
Combine like terms:
2x-106
Hope this helps!
Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,
It is in the Thousandths place
The value of x in D o,k (x,9) -> (-10,-6) is (d) 15
<h3>How to determine the value of x?</h3>
The dilation rule is given as:
D o,k (x,9) -> (-10,-6)
Write out the coordinates
(x,9) -> (-10,-6)
Express as fraction
x/9 = -10/-6
Multiply both sides by 9
x = -9 * 10/-6
Evaluate the product
x = 15
Hence, the value of x in D o,k (x,9) -> (-10,-6) is (d) 15

The two triangles we can see in the diagram are similar, which means that their measurements are proportional. Line MN on the larger triangle MNP is 71.5ft long, and its corresponding line, MA, on the smaller triangle is 71.5-22= 49.5ft long. This means that the scale factor from the bigger to the smaller triangle is 71.5/49.5=13/9.
If line MP on the bigger rectangle is 97.5ft long, then its corresponding line, MB, must be 97.5÷13/9=67.5 ft long.
Therefore, x=67.5 ft
