Answer:
Johnny needs to score 98 on third test to raise average to 94
Step-by-step explanation:
Given that average of two tests is 92.
The score of next test has to be found that means there will be a total of 3 tests.
The average will be:

It is also given that he has to raise his average to 98
We have to use the average formula for finding the third value
So,

Hence,
Johnny needs to score 98 on third test to raise average to 94
Answer:
D (0, 5), (5, 0)
Step-by-step explanation:
Anything with -5 and 0 will not satisfy x+y=5. This eliminates the first three choices.
It is easiest to check the offered answers. You can also solve this graphically, or by solving the simultaneous equations.
You can, for example, square the first equation and subtract the second:
... (x+y)² -(x²+y²) = 5² -25
... 2xy = 0
This will be true for x=0 or for y=0, so (0, 5) and (5, 0) are solutions to the pair of equations.
Answer:
A. is the answer
Step-by-step explanation:
A. Since there is one value of y for every value of x
B. is not a function x = −
4 produces y = 4 and y = 3
C. is not a function x = 6 produces y = 6 and y = 3
D. is not a function
x = 6 produces y = 3 and y = 5
