Answer:
C. 98
Step-by-step explanation:
If you add all of his previous test scores and go through the list of numbers you get C.98 as the answer. I added all of his test scores plus 98 which equals 630 divided by 7 (because if he got a 98 there would be 7 test scores) you would get 90 or an A average.
Answer:
The given expression is equivalent to 3(2^(3/8))x.
Step-by-step explanation:
The given expression (3 root 8^1/4 x) can be written as:
3√(8^(1/4))x
we know that 2^3 = 8
= 3√(2^(3/4))x
We know that √x = (x)^(1/2)
= 3(2^((3/4)(1/2))x
Powers multiply with each other, 3*1/4*2 = 3/8
= 3(2^(3/8))x
Answer:
(-5,17) is a solution to the equation
Step-by-step explanation:
The equation is y = -2x+7
Substitute the values of x=-5 and y =17 into the equation and see if it is true
17 = -2(-5) +7
17 = 10+7
17=17
This is true so (-5,17) is a solution to the equation
