-5x-35=-2x+31 i needa solve work

x=-22

Step-by-step explanation:

first you're going to move the terms , move -2x over to the left side and move -35 over to the right side , you're also going to change their signs , so they're not negative anymore .

next you're going to collect like terms so -5x+2x=3x and then add the numbers 31+35=66

lastly you're going to divide both sides by -3

x=-22 is what you should get

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
