Answer:

since he missed b ill answer it for your b is 24 because when you look at the grragh  it goes from 0 then to 24 so its unit rate would be 24

<span>Table
Bottles Price($)
3           78
6           156
9           234

From that you can find the unit price: 78 / 3 = 156 / 6 = 234 / 9 = 26.

That means that the unit rate of this fragance is $26.

If you call x the number of bottles the equation is

Price = unit rate * number of bottles = 26x.

Now compare this information with that on your graph to compare the unit rates.

This can help you fo find the unit rate in from your grpah: the unit rate is the slope of the line =

[change in y-coordinate] / [change in the x-coordinate]

Tax = $55 * 9% = $55 * 0.09 = $4.95 

Tip = $55 * 18% = $55 * 0.18 = $9.90 

Total = $55 + $4.95 + $9.90 = $69.85</span><span>

Paula runs a bakery. She estimates that her weekly cost of rent and electricity is $250. The ingredients to bake one cake cost $
Gelneren [198K]

Answer:

B. Y=4x+250

Step-by-step explanation:

Y= total cost for Paula's bakery per week

Cost of rent and electricity=$250

Ingredients for 1 cake =$4

Number of cake=x

Cost of x cake=$4*x

=$4x

Total cost (Y)=cost of rent and electricity+cost of making x cake

Y=$250+$4x

It can also be written as

Y=4x+250

Which statement is the correct interpretation of the inequality −2 &gt; −3?
evablogger [386]

The second one.


First of all, all the options involving zero make no sense, since it is not present in the inequality.


Then, the number line has a direction, which is rightwards. This means that the numbers get bigger and bigger as you walk the line to the right.


So, if x>y, it means that x is located to the right of y

The graph of the quadratic function y = ax^2 + bx + c is given.<br> Find a + b + c.
andrey2020 [161]

Answer:

\frac{145}{24}\approx 6***

Answers may vary depending on the person reading the graph.

It is hard to tell what they think crosses nicely.

For example, I decided that the graph crossed nicely at the following points:

(0,3)

(2,8)

(6,5)

Step-by-step explanation:

I see that the graph crosses at (0,3),(2,8), and (6,5).

The equation y=ax^2+bx+c tells us the y-intercept is c since when x=0 we have y=a(0)^2+b(0)+c=0+0+c=c.

The y-intercept for our graph is 3. Therefore, c=3.

So far we have the equation:

y=ax^2+bx+3.

Let's enter the other points creating a system of linear equations to solve:

8=a(2)^2+b(2)+3

5=a(6)^2+b(6)+3

Let's simplify:

8=4a+2b+3

5=36a+6b+3

Let's subtract 3 on both sides:

5=4a+2b

2=36a+6b

I choose to solve the system by elimination.

Let's multiply the top equation by -3:

-15=-12a-6b

2=36a+6b

Now adding the equations results in:

-13=24a

Divide both sides by 24:

\frac{-13}{24}=a

Now using one of the equations we can find b:

5=4a+2b with a=\frac{-13}{24}

5=4\frac{-13}{24}+2b

5=\frac{-13}{6}+2b

Add 13/6 on both sides:

5+\frac{13}{6}=2b

\frac{30+13}{6}=2b

\frac{43}{6}=2b

Divide both sides by 2:

\frac{43}{2(6)}=b

\frac{43}{12}=b

So we have the equation:

y=\frac{-13}{24}x^2+\frac{43}{12}+3

Let's evaluate a+b+c now:

\frac{-13}{24}+\frac{43}{12}+3

\frac{-13+86+72}{24}

\frac{73+72}{24}

\frac{145}{24}
