Answer:

y = 11

Step-by-step explanation:

8 × 2 + 5²- y = 2(y + 1) + 6

8 × 2 + 5²- y = 2y + 2 + 6

8 × 2 + 25 - y = 2y + 2 + 6

16 + 25 - y = 2y + 2 + 6

41 - y = 2y + 8

41 (- y + y) = (2y + y) + 8

41 = 3y + 8

41 - 8 = 3y (+ 8 - 8)

33 = 3y

33/3 = 3y/3

y = 11

MATH: Composition of two functions...help needed with this problem

Evgesh-ka [11]

The equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

<h3>How to determine the formula of Q(n)?</h3>

The functions are given as:

$R(d) = \frac89 d$

$P(n) = 88n + 23$

From the question, we understand that:

d = P(n)

This means that:

d = 88n + 23

Substitute d = 88n + 23 in R(d)

$R(n) = \frac89 * (88n + 23)$

Also, from the question

Q(n) = R(n)

So, we have:

$Q(n) = \frac89 * (88n + 23)$

Hence, the equation of Q(n) is $Q(n) = \frac89 * (88n + 23)$

a) On Wednesday, Harry sold 3 times as many candy bars as on Tuesday. On Thursday, he sold 5 times as many bars as on Wednesday.

Alborosie

Answer:

Tues=8 Weds=24 Thurs=120

Step-by-step explanation:

The question can be modeled by the equation x+3x+15x=152

x is the amount sold on tuesday, 3x is 3 times the amount sold on tuesday so it represents wednesday and 15x represents thursday as it is 5 times the amount sold on wednesday.

Now we just need to solve for x to figure out how many he sold each day.

x+3x+15x=19x

19x=152

x=152/19

x=8

To find the amount sold on each day just mulitiply x by the coefficient

Tuesday = x = 8

Wednesday = 3x = 3*8 = 24

Thursday = 15x = 15*8 = 120
