Answer:

Yes, you can add them together.

Step-by-step explanation:

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Solve this system of linear equations. Separate the x- and y-values with a comma. -7x + 2y = -8 -16x + 9y = 26
Goryan [66]
(4,10). 
1. There are three ways to solve this: elimination, substitution, graphing.
2. I chose elimination, so I had to get one negative variable and one positive variable of the same value (for example, 18 and -18)

-7x+2y=-8
-16x+9y=26
I chose to get 2y and 9y to equal -18y and 18y. 
So, multiply the first equation by -9. Multiply the second by 2.
63x-18y=72
-32x+18y=52
the 18s cross each other out. So you're left with
63x=72
-32x=52. Add them. 
31x=124, divide both sides by 31, and you'll get 4. 
x=4
Plug your answer for x into one of the equations. Let's use the first one.
-7(4)+2y=-8
-28+2y=-8. add 28 to both sides.
2y=20, divide both sides by 2.
y=10. 
This makes your answer (4,10)

3. Which temperature during the week is the closest to 0? Explain how you decided this using absolute value.
Katen [24]

Answer:

The closest temperature to zero during the week is -0.5 °F because it's absolute value, 0.5, is smaller than the other numbers.

The farthest temperature from zero during the week is 5 °F because it's absolute value, 5, is the highest out of all the other numbers.

Answer: The coldest temperature would be -4 °F, because it is the farthest number on the left side of zero on the number line.15-May-2020

The warmest temperature would be 5 °F, because it is the farthest number on the right side of zero on the number line.
