Answer:
We can't see your answer choices, but it would be n + d = 368 and .05n + .10d = 28.40
Step-by-step explanation:
We need to find the solution to:
(85 + 83 + 98 + 77 + x) / 5 >= 84 where x is the score in the last test
This is the same as:
(343 + x) / 5 >= 84
Multiplying both sides by 5 we get
343 + x >= 420
Subtracting 343 from both sides we get
x >= 77
There for the student must get a score of at least 77 on the last tests.

Answer:
The slope is 2.25
The y-intercept is 3
Step-by-step explanation:
Assuming from the cut off picture, that we need to find the slope of ...
y=2.25x +3
y=mx+b form makes it easy to identify the slope and the y-intercept.
m is the slope and b is the y-intercept. Anything number that is in place of m, is the slope; and any nother in place of b is the y-intercept.
In that case, 2.25 is the slope and 3 is the y-intercept
