Step-by-step explanation:

Eva has borrowed 150 songs from her friend. 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:

A graph titled Song Downloading shows Number of Weeks on x-axis and Number of Songs Left to Download on y-axis. The x-axis scale is shown from 0 to 5 at increments of 1, and the y-axis scale is shown from 0 to 280 at increments of 40. A straight line joins the ordered pairs 0, 200 and 1, 160 and 2, 120 and 3, 80 and 4, 40 and 5, 0.

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)

Answer:

it is not a function

Step-by-step explanation:

if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y

(-13,4) and (-13,9)

because you have two different y values for the same x it would fail the vertical line test and thus is not a function

Answer:

I have no idea but okay

Answer: x

Step-by-step explanation:

x

Answer:

The opposite angle of 85=85

The angle facing it is 82 (180_98)

X=(180-[82+85])=180-167

Answer =13 degrees

Answer:

[tex]m= 20b-45[/tex]

Step-by-step explanation:

Given data

The difference between the amount she sells each birdhouse for and the cost of supplies to build each birdhouse is $20

This means that her profit = $20

the number of birdhouses = b

cost of tools= $45

Hence the amount she earns from selling b houses is given as

[tex]m= 20b-45[/tex]

Step-by-step explanation:

for A

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 3 - 1 = 2 \\ an = 1 + (n - 1) \times 2[/tex]

for B

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 9 - 1 = 8 \\ an = 1 + (n - 1) \times 8[/tex]

a. y= 5

b. x=2

c. x= -?

I'm stuck on the last one but I'll tell you how to do it.

For a. I looked at line one and you see that it's on 5? well that is written as y= 5 because there is not x coordinate.

(please people add to this explanation/ answer this question better)

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2

Answer:

it depends on how big her study is-

but ig it could be 5= 260 dollars

Step-by-step explanation:

Answer:

slope = y'-y/x' - x

= 2-(-2)/3-2

=2+2 /1

=4

slope = 4

Answer:

option d

Step-by-step explanation:

This is because Sample Space is collectio of all the outcomes and in this question ( 1,2,3,4,5,6,7,8) is sample space

while 5 is the the outcome , so Outcome shown is 5

Hope the above solution will help you

Answer:

36cm

first we extend one of the half lines.

now we have 2 rectangles with sides

using area of rect formula we find the area of both the rects separately and then add them

Answer:

Step-by-step explanation:

Adjacent angles must sum to 180 degrees.

x+32=180

x=148 degrees

Answer:

x= 148

Step-by-step explanation:

line CD is a straight angle which means it is 180 degree

to find x you must subtract the known angle from the straight angle

your equation should look like this

180-32=148

you can draw it on a graph like the one i did

then name the sides

and then measure them and make sure that parallel sides are equal

a must be = c and have same slope

and

b must be = d and have same slope

after doing that, you will know that this is a correct parallelogram

Answer:

[tex]L(x) = 360 - 15 w[/tex]

Step-by-step explanation:

See comment for complete question

Given

[tex]Amount = \$360[/tex]

[tex]Rate = \$15[/tex] weekly

Required

Determine the function to represent the scenario

The amount (L) owed in w weeks is represented as:

[tex]Amount\ Owed = Amount - Rate * Weeks[/tex]

We used negative because the amount reduces weekly.

So, we have:

[tex]L(w) = 360 - 15 * w[/tex]

[tex]L(x) = 360 - 15 w[/tex]

Answer:

g=10

Step-by-step explanation:

[tex]\frac{7}{g} =\frac{35}{50}\\[/tex]

We can cross multiply so that would be:

[tex]35g=50*7 \\35g=350 \\g=10[/tex]

Hope this helps and answers your question! Have a great day/night!

Answer:

X= 5.44  y= 17.85

Step-by-step explanation:

Given that your B angle is 60 degress you can use 17tan(60) to get X which is 5.44.

Then you a²+b²=c² to find y.

y=√17²+5.44²

y= 17.85

Answer: X= 5.44  y= 17.85

Hope this helps
