Plug in 38 for f(x)
38 = 2(x-1)2 + 6
Use distributive property
38 = 2x-1 * 2 + 6
38 = 2x -2 + 6
38 = 2x + 4
34 = 2x, x = 17
I believe x is 17

What is the distance between (8, -3), (4,-7)?

Papessa [141]

Answer:

$4\sqrt{2}$ which is none of your choices....

Did you mean (8,-3) and (4,-7)?

Step-by-step explanation:

We need to first find the distance between the x's.

Then the distance between the y's.

The distance between the x's is 8-4=4.

The distance between the y's is -3-(-7)=4.

So the distance between two points $(x_1,y1)\text{ and }(x_2,y_2)$ is $\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$ .

So we already found x1-x2 and y1-y2 so now we have:

$\sqrt{(4)^2+(4)^2}$

$\sqrt{16+16}$

$\sqrt{2(16)$

$\sqrt{16}\sqrt{2}$

$4\sqrt{2}$

Elvira’s cafeteria has cartons of milk that are typical of school lunch. The milk supplier charges $0.35 per carton of milk, in

FromTheMoon [43]

Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
