I believe it would be D sorry if I’m wrong good luck!!
It is the 3rd answer, y+6= 13(x+2) since the the point slope formula is
y-y1 = m(x-x1)
you plug the y-value of the coordinate point into y1 and you plug the x-value of the coordinate into x1. You plug the slope into m.
Answer:
3 Pages
Step-by-step explanation:
- Let the pages of economics read = e
- Let the pages of psychology read = p
- Let the total time taken on each instance=t
In the first instance, the student has time to read 50 pages of psychology and 10 pages of economics.
The student could read 30 pages of psychology and 70 pages of economics.
Since the two situations take the same amount of time, we have:
50p+10e=30p+70e
Collect like terms
50p-30p=70e-10e
20p=60e
Divide both sides by 20
p=3e
Therefore, in the time it will take the student to read 1 page of psychology, the student can read 3 pages of economics.
4.2 the 2 is in the tenths place so you round it using the 3 because it is the first one behind it and 3 is less than 5 so it just stays at 2 so your answer is 4.2
