Why did u spread that so much
1/4-3/7*7/8 = 1/4 - 3/8 = 2/8 - 3/8 = -1/8
You have to find the equation that would fit the situation which would be 57,000+800x= population. Then the difference in the years from the year you are trying to figure out to 1980 is plugged in for x. so you would do 2015-1980=35 you would then plug in 35 of x in the equation. 57,000+800(35)=85,000.
Since you didn't give the original picture, I can only explain the process. Then, you need to select the correct point.
In a dilation, we multiply the coordinates by the scale factor. Take the points that you have and multiply them all by 4. Then, look for a point making your new coordinates.
This is a quadratic equation because it has degree 2.
As known as a parabola
B.)
I can tell because the sin func starts from the top at 0 (if sin is positive)
