(6,-2) is true for 4x-3y=30 but NOT for 3x+2y=22.

4*6=24

3*(-2)=-6

24-(-6) changes to 24+6 which equals 30

24+6=30.

3*6=18

2*(-2)=-4

18+(-4) would be changed to 18-4

18-4=14

The temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer. It may reach a low of -225 degre

Triss [41]

Answer: See explanation

Step-by-step explanation:

Since we are informed that the temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer and may also reach a low of -225 degrees Fahrenheit at the poles.

The expression that gives the difference between those temperatures would then be calculated as:

= 70°F - (-225°F)

= 70°F + 225°F

= 295°F
