Answer:
5x-7 has to equal to something smaller than 13
5x-7=5
Answer:
7/8
Step-by-step explanation:
If Haley bought 3/8 pounds of mozzarella and 1/2 pound of parmesan cheese we can convert 1/2 to eighths.
1/2 converted to eighths would be 4/8
4/8 + 3/8 = 7/8
She bought 7/8 pounds of cheese.
Answer:
24!
Step-by-step explanation:
I will refer the people to A,B,C, and D
24 is the answer.
4 choices for the first position.
3 choices for the second.
2 choices for the third.
1 for the fourth.
4*3*2*1=24
Here it is listed out where a,b,c,d are the 4 people:
abcd
abdc
acbd
acdb
adbc
adcb
bacd
badc
bcad
bcda
bdac
bdca
cabd
cadb
cbad
cbda
cdab
cdba
dabc
dacb
dbac
dbca
dcab
dcba
(of course, this assumes that there is a direction to the line, or a 'front' and a 'back'. If direction doesn't matter then the answer is 12, since every combination above has a reverse. e.g., abcd and dcba. The list becomes:
abcd
abdc
acbd
acdb
adbc
adcb
bacd
badc
bcad
bdac
cabd
cbad

Answer: -2/3</h3>
================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (8-6)/(2-5)
m = (2)/(-3)
m = -2/3
As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.
The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.
The answers are A., C., and E.
The chart shows that Camila has a greater rate of change than Lydia, so B is incorrect. C and E are true because the graph shows that Camila's rate of change is $7/hour, making C true, which means that in 2 hours, she gets paid $14, making E true.
Answers: A., C., and E.
Hope this helps! :)
