Answer:
80
Step-by-step explanation:
The "difference" means the answer using subtraction. Subtract -60 from 20 to find the different between the two numbers.
20 - (-60) When you have two minus signs, it become a plus sign.
= 20 + 60 Add
= 80 Difference between the numbers
Could you do it backwards? Subtract 20 from -60? Yes, but since the difference between two numbers will always be a <u>positive number</u>, you need to use absolute value symbols.
| -60 - 20 | Do -60 -20 first
= | -80 | Apply the absolute value of -80 (make the number positive)
= 80 Difference between the numbers
You do not have to put absolute value if you do 20 - (-60), but you can. For -60 -20, you must use them.
Therefore, the difference between 20 and -60 is 80.
Answer:
Step 1
Write and solve the inequality:
2,500 + 40a ≥ 4,000, or 40a ≥ 1,500
a ≥ 37.5
Step 2
If the shelter places 30 cats and 10 dogs,
or 40 animals, that will be enough to meet
its goal, because a = 40 is a solution to the
inequality a ≥ 37.5.

Answer:
B) m = 2 , b = -3
Step-by-step explanation:
b = y-intercept
The y-intercept is -3
b = -3
m = slope
The slope is 2
m = 2
Answer:
D
Step-by-step explanation:
We know that vector addition is scalar addition.
Given vectors are u = <-3.5, -1.5> and v = <-1.25, 2.25>
2v = < -2.5, 4.5>
2v - u = < -2.5, 4.5> - <-3.5, -1.5> = < -2.5 - (-3.5) , 4.5 -(-1.5) >
2v-u = < 1 , 6 >
This vector is basically i + 6j which is drawn in option D
