Answer:The answer is d which is 25
Step-by-step explanation: No Explain Sorry
5y + 7 < = -3
5y < = -3 - 7
5y < = -10
y < = -10/5
y < = -2
3y - 2 > = 13
3y > = 13 + 2
3y > = 15
y > = 15/3
y > = 5
Answer:
5 word problems(4points each) & 10 open (3 points each)
Step-by-step explanation:
O= open response
W= word problems
W+O =15
4W + 3O = 50
multiply the first by -3 to eliminate O
-3W -3O = -45
4W + 3O = 50
AD BOTH
W = 5 ( 5 questions word problems)
O= 10 ( 10 questions open response)
5x4 = 20
10x3 = 30
20 + 30 = 50 points
The price of the stereo on sale
is
275 - ( 275x15% ) =

Answer:
(2/3)(e^t +1)^(3/2)
Step-by-step explanation:
Use the substitution ...
u = e^t +1
Then du = e^t and you are finding the integral of ...
∫u^(1/2)·du
which you know by the power rule is ...
(2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)
