(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
Step-by-step explanation:
1. first draw a table for x and y values
2. use any x values (preferable -3 to 3)
3. put that x value in equation, and find y
4. plot those points on graph and join the points
hope it helps! please mark me brainliest...
thank you..have a good day
So first convert to common denomenator( bottom number)
'
4 and 14
find least common multiple
factor
4=2 times 2
14=2 times 7
Least Common Multiple=2 times 2 times 7=28
1/4 times 7/7=7/28
8/14 times 2/2=16/28
add
5 1/4+8/14=5+1/4+8/14=5+7/28+16/28=5+23/28
the answer is 5 23/28
Answer:
5. Not sure
6. Its linear since the first difference is constant.
7. Linear since its a line.
8. Slope/Rate of Change/M = Rise over Run = rise/run.
From the left point to the right, the rise is 3 and run is 10.
M = 3/10.
