Does that help any?
Answer:
S(0, 2)
Step-by-step explanation:
Midpoint Formula: 
Step 1: Plug in known variables
5 = (10 + x)/2
-8 = (18 + y)/2
Step 2: Solve
10 = 10 + x
x = 0
-16 = 18 + y
y = 2
Step 3: Write coordinates
(0, 2)
Answer:
1) -1/3
2) 4
3) 5/2
4) 5/7
Step-by-step explanation:
To find slope, you must do rise/run, where rise is movement up and down, and run is movement left and right.
So just start from the left most point and count the little unit squares up or down to determine rise and then count them left or right to determine run, do this until you get to the next point. (If it's a positive slope then the line will go up to the right, and if it's negative then it will go down to the right).
For example: In the first graph, since the line is going down, the slope is negative. As you can see it goes down 1 and over to the right 3, so that's why it's presented as -1/3.
Hope this helps :)
1. 3x=18; you divide each side by 3 because you want to get the x by itself. When you do that, you get x=6.
2. Y+4=11; you subtract each side by 4 because you want to get the y by itself so you do the opposite of that is in front of the +4 (-4). When you do that, you get y=7.
3. W/5=6; you multiply each side by 5 because to get rid of the 5, you multiply(or do the opposite(inverse)) to get the w by itself. That would leave you with w=30.
4. 135=p+21; you subtract each side by 21 to get 114=p.
5. 2m-3=13; the easiest thing to do is to add 3 to both sides to get 2m=16. After that divide both sides by 2 to get m=8.
6. 3/4+a=2 1/4; if it's easier, turn the fractions into a decimal. Subtract both sides by 3/4 to get 1 1/2. a=1 1/2
2 numbers are called relatively prime if their Greatest Common Factor is 1.
For example, GCF(2, 6) = 2, not 1, so 2 and 6 are not relatively prime.
whereas, GCF(3, 8)=1, so 3 and 8 are relatively prime.
3 sets of relatively prime numbers are :
{4, 5}, {7, 9}, {9, 16}
Answer:
{4, 5}, {7, 9}, {9, 16}
