Answer:
The upper graph
Step-by-step explanation:
We have two quadratic function here
If we perform the function f(x) + g(x), which is nothing more than the sum of the two functions, we obtain a linear function, since the quadratic terms are eliminated by themselves
Answer:
Step-by-step explanation:
Let d represent the number of dimes. Then 81-d is the number of nickels and the total value in cents is ...
10d +5(81-d) = 530
5d +405 = 530 . . . eliminate parentheses
d +81 = 106 . . . . . divide by 5
d = 25 . . . . . . . . . subtract 81; number of dimes
81 -d = 81 -25 = 56 . . . . . number of nickels
There are 25 dimes and 56 nickels in the box.

Answer:
886 cm²
Step-by-step explanation:
34 x 16 = 544
11 x 19 = 209
25-11= 14
14 x 19 = 266 / 2 = 133
133 + 544 + 209 = 886
