Seven people went to the movies. The number of adults was one more than the
Children. Write a system of equations that
represents the number of adults and child-
ren. Solve the system algebraically.

3 kids, 4 Adults

Step-by-step explanation:

x = kids

y = adults

Total = 7

x + y = 7

y = x + 1

do a bit of solvin, too much to type lol

2x = 6

x = 3

And since X = 3  and Y = X + 1

Y = 3 + 1 = 4

the answer will be the last one

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
