Answer:

Step-by-step explanation:

We want to make equation into slope intercept form.

Like this: y=mx+b

(mx and b are interchangeable)

Step 1) Convert equation

8x-5y=-11

Sub Step a) subtract 8x on both sides

8x-5y=-11 => -5y = -11-8x

-8x -8x

Sub step b) get y alone

-5y/-5 = -11/-5 - 8x/-5

Equation: y = 11/5 + 8x/5

Step 2) Y-intercept

B is the y-intercept.

B = 11/5

y-intercept is (0,11/5)

Step 3) X-intercept

Substitute 0 for y in our equation

0=11/5+8x

Subtract 8x on both sides

-8x = 11/5

Divide by -8 on both sides

x = -11/40

x-intercept is (-11/40,0)

Answer:

x-intercept: (-11/8, 0)

y-intercept: (0, $2\frac{1}{5}$ )

Step-by-step explanation:

x-intercept means the y-coordinate is 0

x-intercept: (x, 0)

Substitute y with 0

8x - 0 = -11

8x = -11

x = -11/8

x-intercept: (-11/8, 0)

y-intercept means the x-coordinate is 0

y-intercept: (0, y)

Substitute x with 0

0 - 5y = -11

5y = 11

y = 11/5 = 2 1/5

y-intercept: (0, $2\frac{1}{5}$ )

Hope this helps :)

Answer:

20mins

Step-by-step explanation:

3/4 * 60 = 45 mins

1/4 * 60 = 15mins

15mins + 10mins = 25 mins

45 - 25 = 20mins

The daily profit P (in thousands of dollars) from the sale of televisions is a function of the number x of televisions sold (

scZoUnD [109]

Answer:

The break-even sales amounts is 36 or 224.

Step-by-step explanation:

Consider the provided function.

$P= -5x^2 + 13x - 4$

Where x is the number of televisions sold (in hundreds) and P is the profit.

We need to calculate the break-even sales amounts.

the break-even sales amounts is the sales amounts that result in no profit or loss.

That means substitute P=0 and solve for x.

$-5x^2 + 13x - 4=0$

$5x^2-13x+4=0$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Substitute a=4, b=-13 and c=4 in above formula.

$x_{1,\:2}=\frac{-\left(-13\right)\pm \sqrt{\left(-13\right)^2-4\cdot \:5\cdot \:4}}{2\cdot \:5}$

$x_{1,\:2}=\frac{13\pm\sqrt{169-80}}{10}$

$x_{1,\:2}=\frac{13\pm\sqrt{89}}{10}$

$x=\frac{13+\sqrt{89}}{10},\:x=\frac{13-\sqrt{89}}{10}\\x\approx2.243, \ or\ x\approx 0.357$

Therefore, the break-even sales amounts is 36 or 224.

a group of friends went to lunch. the bill, before sales tax and tip, was $37.50. a sales tax of 8% was added. the group then ti

valentina_108 [34]

First, there was $37.50.
Then, there was a tax of 8%.
Then, there was a tip of 18%.
Since the tip is after the tax, it's not going to affect it, and we can essentially ignore it.

The real question here is just <em>what is 8% of $37.50?</em>

To find the percent of something, first you need to put the percent as a decimal.

8% in decimal form is 0.08 (If you think about it literally, they're both 8 hundredths)

Finally, just multiply the percent in decimal form by the number.

37.50 dollars × 0.08 = 3 dollars.<em />
