Answer:

$y = \frac{2}{5}x + 3\frac{2}{5}$

Step-by-step explanation:

This line was never finished, so you finish it like this:

$\frac{5y}{5} = \frac{2x + 20}{5} → y = \frac{2}{5}x + 4$

3 = −⅖ + b

$3\frac{2}{5} = b \\ \\ y = \frac{2}{5}x + 3\frac{2}{5}$

Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅖ remains the way it is.

I am joyous to assist you anytime.

As a waitress, at the end of the night you have to tip 3% (same as 1/33) of your total earnings to the bussers and hosts.

equation:
total earnings (E) times (3% or 1/33)= money tipped to bussers and hosts(T).

E*1/33=T

HELP PLEASE. A pizza shop charges customers based on the area of the pizza they order. The cost of a pizza in dollars can be rep

san4es73 [151]

For this case we have that the cost of each pizza is given by the following function:

$S (r) = 0.1 \pi * r ^ 2$

Where:

r: It's the radius of the pizza

IF a pizza cost $26.32 we have:

$26.32 = 0.1 \pi * r ^ 2$

We cleared the radius, using $\pi = 3.14$ :

$\frac {26.32} {0.1} = \pi * r ^ 2\\263.2 = 3.14r ^ 2\\\frac {263.2} {3.14} = r ^ 2\\83.82 = r ^ 2\\r = \pm \sqrt {83.82}$

We choose the positive value:

$r = 9.15$

So, the radius of the pizza is $9.16 \ in$

Then, the diameter is: $2r = 2 * 9.15 = 18.30 \ in$

Finally, the diameter of the pizza is: $18.30 \ in$

How many integers n leave remainder 4 when divided by 7, if n satisfies the given inequality?

bekas [8.4K]

Consider inequality $|-n|$ This inequality is equivalent to inequality $|n|$

This means that $-46$

The greatest integer number n, such that $-46$ when dividing by 7 gives the remainder 4 is 39. Then subtract 7, you get 32, then 25 and so on.

When n=-39, -32, -25, -18, -11, -4, 4, 11, 18, 25, 32, 39 then dividing by 7 the remainder is 4.

Answer: 12 integers.
