If she has already watched 1.5 hours and she can only watch 5 hours per week, then we have the inequality:
1.5 + T ≤ 5
where T is is the number of hours she can watch more before reaching her limit

If he needs 100 points, already has 40 and earns 2 for every movie, we have the inequality:
40 + 2m ≥ 100
where m is the number of movies he needs to watch

We can have the equation:
x + 1 = x + 2 - 1
This would result to:
x + 1 = x + 1
which have the same terms on both sides.
Further, the equation would be:
0 = 0
Answer:
x2+16
Step-by-step explanation:
A Yes as the x values are all different
B f(x) = 5x + 14
when x = 2 , f(x) = 5(2) + 14 = 24
x = 5, f(x) = 39,
Each value of f(x) is greater than corresponding ones in the function in A.
when x = 9 f(x) = 59 which is greater than for first function ( =12)
First function is a decreasing while f(x) is increasing
C f(x) = 64 = 5x + 14
5x = 64 - 14 = 50
x = 10
Friday - 185
Saturday - 185 x 2
= 370
Sunday - 370 - 50
= 320
B. 2 2/9 hours.
in 2 hours the will already have made 96 cupcakes so the only logical answer is B
