P=10-2.5c, find p when c = 3.2 and then find c when p = 85

Answers

Answer 1

Answer: P=10-2.5c
P=10-2.5(3.2)
P=10(-8)
P=18

P=10-2.5c
85=10-2.5c
-10 -10
75=-2.5
75 divided by 2.5
C=-30

URGENT!!! HELPGina has purchased 100 songs from the internet. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:

(Graph attached below)

Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)

Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points)

Answers

Answer:

Initial value is 100

Step-by-step explanation:

A) rate of change would be dividing the number of songs wanted (100) by the number of weeks downloading (5)

100/5 = 20

since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -20

Initial value is 100, which is the total number of songs they want

Answer:

Part A:

initial value = 100 (total amount of songs to download)

rate of change = -20 songs/week (100-80 and so on)

Part B:

y = -20x + 100

What's 3/4x=1/8? because i don't know

Answers

ok so it could be 2 things
(3/4)x=1/8 or
3/(4x)=1/8

if it is (3/4)x=1/8, go to AAAAAAAAAAAAA

if it is 3/(4x)=1/8 go to BBBBBBBBBBBB

AAAAAAAAAAAAA
(3/4)x=1/8
multiply both sides by 4/3 to clear fraction ( since 3/4 times 4/3=12/12=1)
1x=4/24
x=1/6

BBBBBBBBB
3/(4x)=1/8
multiply both sides by 4x
3=(4x)/8
multiply both sides by 8
24=4x
divide bohs ides by 4
6=x

if it is (3/4)x=1/8, then x=1/6
if it is 3/(4x)=1/8, then x=6

To get the answer, you have to isolate x by multiplying by the reciprocal of the coefficient:
$(3)/(4)x= (1)/(8) \n (4)/(3) ( (3)/(4)x)= ((1)/(8) )( (4)/(3)) \n (12)/(12)x= (4)/(24) \n x = (1)/(6)$

The answer is x = 1/6.

Hope this helps!
