Answer:

The inverse of the function y = 5x - 10 would be:

5x - 10 = y

5x = y + 10

x = (1/5)y + 2

2 parts compost, 6 parts potting soil for 10 kg of mix. How many kg of compost

likoan [24]

Answer:

Step-by-step explanation:

A proportion could be used.

With 2 parts of compost and 6 parts potting soil, you would end up with 8 total parts.

So it can be written as a ratio of compost to total mix, or $\frac{2}{8}$

The problem states 10 kg are needed in total, and the variable would be the amount of compost

As a ratio it would be $\frac{x}{10}$ .

Use the ratios to write a proportion.

$\frac{2}{8} = \frac{x}{10}$

Multiply both sides of the equation by 10

$\frac{20}{8} = x$

Convert to a decimal if desired.

$x=2.5$

How to find the perimeter of a square one side is 10x other side is 6x+8?

Yanka [14]

To find the perimeter of the square, you add all four sides together:
10x + 10x + (6x + 8) + (6x + 8)
20x + 12x + 16 = P
32x + 16 = P

you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other.
10x = 6x + 8
4x = 8
x = 2

Now you just plug in x and finish the rest of the problem, and you have the answer:
32(2) + 16 = P
64 + 16 = P
P = 80

(if you find this helpful, marking this as the brainliest answer would make my day :)

Can someone explain to me step by step how to do <br> 5/13x=-9

snow_tiger [21]

$\frac{5}{13} x=-9
$
Multiply each side by reciprocal of 5/13This gives;x=-9* $\frac{13}{5}$
x=-23.4
