262.6/300% for the first 3 test if you were to add another test it would be 400% total and you need 360% of test grades to have an average of 90% and so 360 - 262.6 = 97.4%

Answer:
37
Step-by-step explanation:
To find the answer to this equation, we need to substitute 5 into where x is in the original equation.
f(x) = 8x-3
f(5) = 8(5)-3
f(5)= 40-3
f(5)= 37
and that's it! no further simplifying.
Y = k / x
2 = k / 4
k = 8
Therefore, the answer for this question would be (4,2)
Answer:
