Answer:The value of the expression increases as r decreases.

Step-by-step explanation:

To find : What happens to the value of the expression as r decreases?

Given Expression: 80-2r

We check for different value of r as decreasing order,

r        80-2r

5        80-10=70

4        80-8=72

3        80-6=74

2        80-4=76

1         80-2=78

As r decreases the value of expression increases.

Therefore, the value of the expression increases as r decreases.

Hope this helps!

Answer:

If r is a smaller number, the value increases. If r is larger, the value will decrease.

For instance:

80-2(4)

80-8=<em>72</em>

80-2(2)

80-4=<em>76</em>

Can someone help my sis on these questions? I dont remember how to do these things (part 1)
NNADVOKAT [17]

Answer:

Read below for each answer! (^-^)

Step-by-step explanation:

1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.

2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.

3: 7. That's the greatest number both can divide into it.

4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.

5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.

Hope this helps!

What is the distance between points A and C?<br> 3.3 units<br> 3.6 units<br> 5.2 units<br> 7.8 units
artcher [175]

Answer:

AC ≈ 7.8 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = A (- 4, - 4 ) and (x₂, y₂ ) = C (2, 1 )

AC = \sqrt{(2-(-4))^2+(1-(-4))^2}

      = \sqrt{(2+4)^2+(1+4)^2}

      = \sqrt{6^2+5^2}

     = \sqrt{36+25}

     = \sqrt{61}

     ≈ 7.8 ( to 1 dec. place )
