For y=2x+125, the slope is 2, which means that the total will increase by 2, and the y-intercept is 125, and that is the starting value. So, y=2x+125 goes with the second choice on the right. For y=1/2x+125 means that 125 is still the starting value but instead of the total amount increasing by 2, it is divided by 2 and goes with the first choice on the right. For y=125x+2, the slope is 125 and 2 is the y-intercept, so the answer is the last one on the right.

2.1 is greater
Step-by-step explanation:
Answer:
The answer is X=5
Step-by-step explanation:
2x - 5x = 7-8
-3x = -15
X= -15: (-3)
X=5
Answer:
<u>The correct answer is B. Exponential form.</u>
Step-by-step explanation:
The exponential form was developed to express repeated multiplications and to make it easier to write long numbers. The exponential notation has two parts. The base, as the name says, is the number below. The other part of the notation is a small number written on the superscript to the right of the base, called an exponent. We will use an example to learn about the exponential form or notation.
2³
In this example the base is 2. This means that 2 is a factor, and that it will be multiplied by itself a certain number of times. The precise number of times is given by the exponent, the number in the superscript. In this case, the exponent is 3, which means that base 2 will be used as a factor 3 times. So 2³ means 2 • 2 • 2 and the result is 8.
X=-3 because first substitute the value of y into the original equation -2x-3=x+6 then isolate the variables -2x-x=6+3 which is -3x=9 then we can divide x=9/-3 which =-3
