Answer:

8/7

Step-by-step explanation:

$\displaystyle\left(\frac{g}{f}\right)(-2)=\frac{g(-2)}{f(-2)}=\frac{7(-2)-2}{-2(-2)^2+3(-2)}\\\\=\frac{-16}{-8-6}=\boxed{\frac{8}{7}}$

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 poun

artcher [175]

Answer:

A. 10 bricks

B. 4 pounds

Step-by-step explanation:

Water = 39 pounds

brick dust = 48 pounds

Total mixture = water + brick dust

= 39 + 48

= 87 pounds

She spills 13 pounds of the mixture while stirring

Remaining mixture = Total mixture - Spillage

= 87 pounds - 13 pounds

= 74 pounds

The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture

Number of bricks made = Remaining mixture / pounds per brick

= 74 pounds / 7 pounds

= 10 bricks remaining 4 pounds of the mixture

A. What is the greatest number of bricks Lynn can make?

10 bricks

B. How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?

4 pounds

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: $\displaystyle d = \sqrt{74}$

F(x)=(2x+3)(x-2) and g(x)=2x2-16. Find g(x)-f(x)

babymother [125]

G(x) - f(x) = -x - 10

First, simplify f(x).
(2x+3)*(x-2) = 2x^2 + x - 16

Next, subtract.

    2x^2       - 16
-   2x^2 + x -   6
---------------------
              - x - 10

The answer is -x -10    assuming that g(x) is 2x^2 - 6
