Which equation is the slope intercept form of this equation?

solmaris [256]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the equation i point-slope form.

Convert to the slope-intercept form:

$y-4=-2(x-5)$ <em>use the distributive property</em>

$y-4=-2x+(-2)(-5)$

$y-4=-2x+10$ <em>add 4 t oboth sides</em>

$y-4+4=-2x+10+4\\\\y=-2x+14$

Find the difference. Enter your answer in lowest terms in the box below as a

lara [203]

Answer:

76/165

Step-by-step explanation:

The difference of fractions can be found using the formula ...

a/b -c/d = (ad -bc)/(bd)

<h3>Difference</h3>

Using the given values in the formula, we have ...

$\dfrac{8}{11}-\dfrac{4}{15}=\dfrac{8(15)-11(4)}{11\cdot15}=\dfrac{120-44}{165}=\boxed{\dfrac{76}{165}}$

Here, the difference fraction does not need to be reduced. Many calculators and spreadsheets can do this arithmetic for you.

The above formula can also be used for sums of fractions. In that case, the sign changes from minus to plus.

Twelve identical cylindrical pop cans are placed in a box. If sand fills the space between the pop cans and the cans and the sid

Masteriza [31]

Answer:

Step-by-step explanation:

I don't see any information on dimensions of the cans or box, so I'll assume the question wants a general solution.

Three steps will result in the volume of sand required to fill the remaining space in the box.

1. Calculate the volume of a can using the equation for the volume of a cylinder: Vol = πr²h

2. Multiply the can volume by 12. This will give the total volume of the 12 cans in the box.

3. Calculate the volume of the box: Volume = (Base)(Width)(Height)

[Make sure the units are the same as those used in calculating the can volume. E.g., if the can is calculated with cm as the measue, the box dimensions must also be cm]

4. Subtract the volume of the12 cans (from step 2) from the volume of the box.

The result from 4 will be the volume of sand required to fill the box containing 12 cans.

I'm not clear why filling the box with sand is important, but perhaps it will absorb any soda released from cans broken when the heavy box is dropped by the person shocked that 12 cans of pop could be so heavy.

cara works at a fine jewelry store and earns a commission on her total sales for the week. her weekly paycheck was in the amount

Gekata [30.6K]

Cara's rate of commission is 12%.

Step-by-step explanation:

Given,

Paycheck = $6500

Salary = $1000

Commission = Paycheck - Salary

Commission = 6500-1000 = $5500

Total sales for the week = $45000

Commission rate = $\frac{Commission}{Total\ Sales}*100$

$Commission\ rate=\frac{5500}{45000}*100\\\\Commission\ rate=\frac{550000}{45000}\\\\ Commission\ rate=12.22\%$

Rounding off to nearest whole number.

Commission rate = 12%

Cara's rate of commission is 12%.
