Answer:
3 1/4
Step-by-step explanation:
1) Convert 6 1/2 into a fraction and add it to 1/2.
6 -> 12/2
12/2 + 1/2 = 13/2
2) Divide the result by 2 (or multiple the result by the reciprocal of 2)
13/2 x 1/2 = 13/4 or 3 1/4
Hope this helped ^^
Answer:
C would be equal to (f - 13)/(10 - d)
Step-by-step explanation:
In order to find this, you must manipulate the equation so that the left side has every term with a c in it. Then you can isolate it by dividing and find what it is equal to.
10c - f = -13 + cd -----> Add f to both sides
10c = f - 13 + cd -----> Subtract cd from both sides
10c - cd = f - 13 ------> Pull out c
c(10 - d) = f - 13 -----> Divide by (10 - d)
c = (f - 13)/(10 - d)
The first box is correct because if drawn on a praph it would show that it has a curve. Also another way to find out if it is nonlinear or linear is because the x-axis is increasing and the y-axis is decreasing. Hope this helps :)
