Answer: 4(x + 9) = 3x − 8 − 5
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
4(x + 9) + 5 = 3x − 8
The subtraction property of equality states that if we subtract the same number from both sides of the equation, the equality remains.
So, if we subtract 5 from both sides:
4(x + 9) + 5-5 = 3x − 8 -5
4(x + 9) = 3x − 8 − 5
Feel free to ask for more if needed or if you did not understand something.
Answer:
B) Undefined
Step-by-step explanation:
Vertical lines do not have a horizontal change; the line goes straight up and down. In other words, the change in the x values between any points on the graph is always 0, which would make the denominator of the slope 0. Since anything divided by 0 is undefined, the slope of a vertical line is <u>undefined</u>.

Answer:
120 cm squared
Step-by-step explanation:
Answer:
1600
Step-by-step explanation:
1.25x + 1000 = 3000
Subtract 1000 from both sides
1.25x = 2000
Divide both sides by 1.25
x = 1600
I believe that the answer is 90x+27
