Answer: 1058176
check:
1058176 - 709,189= 348,987
1.) C
2.) A
3.) B
4.) C
5.) idk
6.) A
7a.) non proportional because the line does not pass through the origin (0,0)
7b.) The slope is -2x
7c.) The y-intercept of the line is -3.
7d.) The equation of the line is y = -2x - 3
The two numbers are 21 and -4 because 21×(-4)=(-84). And when you add 21+(-4) you get 17.
The increase is 1150 ... 11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.
