Answer:

10 weeks

Step-by-step explanation:

You start by looking for the number that would help make these equal. it would have to be a number that ended with a 5 or 0. that would be 10. 10x7=70. 70+50=120

120

then 10x10=100+20

120

they will be the same at

10

Graph y=6x−7<br> Identify the x-intercept.
valina [46]

9514 1404 393

Answer:

  x-intercept: 7/6

Step-by-step explanation:

The x-intercept is found by solving for x when y=0.

  0 = 6x -7

  7 = 6x . . . . . add 7 to both sides of the equation

  7/6 = x . . . . divide both sides by 6

The x-intercept is 7/6 = 1 1/6 ≈ 1.167.

__

The y-intercept is the constant in the given equation: -7. The slope of 6 tells you the line rises 6 units for 1 unit to the right. So, the point (1, -1) is another point on the graph. The line through those two points, (0, -7) and (1, -1), will intersect the x-axis at x=7/6.

What is the multiplicative rate of change of the exponential function represented in the table
stepan [7]
We are given the following data
x    y
1     4.5
2     6.75
3      10.125
4      15.1875

To get the multiplicative rate of change, we pick out two pairs of data so,
MROC = 6.75/4.5 / (2 - 1)
MROC = 1.5

The answer is 1.5

This can be easily solved, especially with a calculator.
With the calculator, you can find that \sqrt{42} is about 6.4807.
Multiply that by 2, you get about 13 inches.

If you can't use a calculator, then you can just estimate. Since we know that \sqrt{36} is 6 and \sqrt{49} is 7, \sqrt{42} is in between them, so you can just say somewhere around 6.5.

Multiply 2 * 6.5 and you get 13 inches.
