Answer:

17.) y= x/4

19.) y= (x-1)/3

Step-by-step explanation:

switch the x and y in both equations, so your equations should look like this:

17.) x= 4y

19.) x= 3y+1

17.) divide the 4 on both sides and your equation would be:

y= x/4

19.) subtract the 1:

x+1 = 3y

divide the 3:

y= (x-1)/3

The linear function graphed below represents the value of a comic book since Lucy purchased it. What was the value of the comic

zhuklara [117]

Answer:

C. $25

Step-by-step explanation:

We will find,

The slope of the function using $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

Taking the points (1,40) and (2,55).

Slope = $\frac{55-40}{2-1}$

i.e. Slope = $\frac{15}{1}$

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation $y=mx+b$ ,

We have, $40=15\times 1+b$

i.e. $b=40-15$

i.e. b= 25

Thus, the equation of the linear function is $y=15x+25$ .

<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>

So, the initial value of the comic book is when x= 0.

So, $y=15\times 0+25$ i.e. y= 25

Hence, the cost of the book when Lucy purchased it was $25.

What is the product? (4y − 3)(2y2 + 3y − 5)

Mkey [24]

All ya got to do is break is down

Step 1) 4y(2y2+3y-5)-3(2y2+3y-5)
Step 2) 8y3+12y2-20y-3(2y2+3y-5)
Step 3) 8y3+12y2-20y-(6y2+9y-15)
Step 4) 8y3+12y2-20y-6y2-9y+15
Step 5) 8y3+(12y2-6y2)+(-20y-9y)+15

Then you got to simplify and you have to

Leave the

8y3 +

12-6= number y2 -

-20-9=- number y

Then leave the 15

Sorry your doing the same math as me so I get carried away :p

A store loses twenty-five dollars a day over six days. How much money was lost in total over these six days

yawa3891 [41]

<h2>Answer:</h2>

There was a total loss of $150.00 over those 6 days

<h2>Step-by-step explanation:</h2>

1 - Simplify the word problem

A store makes a loss of $25 per day for 6 days

2 - Write a statement for it

d = days

t = total loss

25d = t

3 - Plug in the days for d

25(6) = t

150 = t

t = $150

There was a total loss of $150.00 over 6 days

Hope this helps :)
