Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answers
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5

Answer:
A. 38 degrees
Step-by-step explanation:
That entire angle is supplementary meaning it will add up to 180 degrees. So we are given 52 and 90 because of the right angle. Those together come to 142 then subtract that from 180 and get 38 degrees.

Step-by-step explanation:
Square= bh
Square= 2×2=
half-circle = 1/2Pi*r×r
half-circle 2 = 1/2Pi*r×r
We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D
Now we need to find the area of the square, which is a^2. The diameter of a circle is double the radius, so we know the sides of the square will equal 4 inches, so 4 x 4.
4 x 4 + 2 x 1/2 x 3.14 x 2^2 should give you your answer. Hope this helps!!

Answers
Answer:
18
Step-by-step explanation:
All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's
========================================================
Explanation:
If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.
Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.
--------------
You could also think of it like this:
Place point A at -12, B at 0, C at 6
The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.
----------------
Or you could use absolute value and subtraction
Let P = -12 and Q = 6
We could say
|P - Q| = |-12-6| = |-18| = 18
or
|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18
The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.

Answer:
Yes! This is my area!
Step-by-step explanation:
Minimum= 51
Maximum=64
To find the median put the numbers in order
51,53,55,58,60,60,64
no cross off one by one to get the middle number
you end up with 58
first quartile is the upper half so that would be 53
third quartile is the lower half so that wou;d be 60
Hope this helps!
Answer:
D
Step-by-step explanation:
when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64
the minimum is the smallest number in the data set. the maximum is the largest number in the data set.
the median is the measure of center, which indicates the middle number in the data set
the first quartile is the center of the bottom set of the data
the third quartile is the center of the upper set of the data
(the upper and lower sets are indicated by which side of the median they are on)
