Mathematics

Cerrena [4.2K]3 years ago
8 0

Answer:

The slope:

m = \frac{15}{13}

Step-by-step explanation:

-To determine the slope of the following points shown, you need this formula:

m = \frac{y_{2} - y{1}}{x_{2} - x_{1}}

(m represents the slope, (x_{1}, y_{1}) represents the first coordinate and (x_{2},y_{2}) represents the second coordinate)

-Apply the following points to the formula:

m = \frac{13 + 2}{8 + 5}

Then, solve:

m = \frac{13 + 2}{8 + 5}

m = \frac{15}{13}

So, the slope is \frac{15}{13}.

a cake using eggs and potatoes in the ratio of 2 to 5 if he uses sex as how many potatoes will he need
tamaranim1 [39]
When eggs = 2, then potatoes = 5

Eggs: 2
Potatoes: 5

When that is changed to 6 eggs, 2 needs to be multiplied by a number to get 6.

2 * what = 6      or      6/2=

you get the number 3. A fraction is equivalent to a ratio. So if you have 2*3=6 then you need to multiply 5*3 to get the amount of potatoes you need. the answer is 15 potatoes because 5*3=15.
