In-s [12.5K]

Answer:

Step-by-step explanation:

We are given

The student council earned $1.25 for every cup of hot chocolate it sold

and $0.75 for every cup of apple cider it sold

total number of cup is 375

We can see that first term is 1.25x

and we have

The student council earned $1.25 for every cup of hot chocolate

so, to find total cost of hot chocolate , we multiplied 1.25 with x

that's why

x must be the number of cups of hot chocolate sold

So the answer must be C

Coordinates (x, y)

Algebra Ii

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find endpoints from graph

Point (-3, -3)

Point (4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(4- -3)^2+(2- -3)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{7^2+5^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{49+25}$
[√Radical] Add: $\displaystyle d = \sqrt{74}$
