1. The coldest place in Utah is Middlesink, near Logan. One day the temperature there was −17 degrees. You drive from Middlesink to Salt Lake where the temperature is 30 degrees. What is the change in temperature? Explain.

47 degrees

Step-by-step explanation:

The difference between the two is 47 degrees. The equation is 30-(-17).

When you subtract a negative it's really the same as adding.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
