Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?
A) because if you add 18x to both sides of the equation and simplify, you get −18=−18
B) because if you add 18 x to both sides of the equation and simplify, you get - 18 = - 18
C) because if you add 18x to both sides of the equation and simplify, you get 0=−18
D) because if you add 18 x to both sides of the equation and simplify, you get 0 = - 18
Answer:
Step-by-step explanation:
Because if you add 18x to both sides of the equation, you get 0 = -18
Step-by-step explanation:
When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.

Choose the statement that tells how the area of the reduced design compares to the area of the original design.
Group of answer choices
The area of the reduced design is the same as the area of the original.
The area of the reduced design is 1/4 of the area of the original.
The area of the reduced design is 1/2 of the area of the original.
The area of the reduced design is 4 times greater than the area of the original.
The original is 5cm, the reduced is 2.5cm
2.5/5 = 0.5 = 1/2
Area is a square measurement, so the area of the reduced image would be the scale squared, which would be 1/2^2 which = 1/4
The answer is:
The area of the reduced design is 1/4 of the area of the original.

Which graph represents the function y = x – 2? A coordinate plane with a line passing through (0, negative 3) and (2, 0). A coordinate plane with a line passing through (0, 2) and (2, negative 1). A coordinate plane with a line passing through (0, negative 2) and (3, 0). A coordinate plane with a line passing through (0, 1.5) and about (2.25, 0).
The graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).
None of the given options is correct
The given equation is:
y = x - 2
Find the x-intercept by making y = 0 and finding the corresponding x-value
y = x - 2
0 = x - 2
x = 2
The line y = x - 2 passes through the point (2, 0)
Also, find the y-intercept by making x = 0 and finding the corresponding y-value
y = x - 2
y = 0 - 2
y = -2
The line passes through the point (0, -2)
Therefore, the graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

55x - 17
55x - 25
Answer:
the answer is the second one, 55x-17
Step-by-step explanation:
So what you do is you open the parenthesis and evaluate and simplify the expression.
Here is the simplification: (7)(9x)+(7)(−3)+(−4)(2x)+(−4)(−1)
=63x+−21+−8x+4
And reduce that further and you get 55x-17.
