Answer:

So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.

f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given

f(5) = <u>3(5)</u> - 4

f(5) = <u>15 - 4</u>

f(5) = 11

f(2) = <u>3(2)</u> - 4

f(2) = <u>6 - 4</u>

f(2) = 2

f(1) = <u>3(1)</u> - 4

f(1) = <u>3 - 4</u>

f(1) = -1

f(10) = <u>3(10)</u> - 4

f(10) = <u>30 - 4</u>

f(10) = 26

f(-1) = <u>3(-1)</u> - 4

f(-1) = <u>-3 - 4</u>

f(-1) = -7

In a study, 8 people ate a total of 1,312 pounds of potatoes in 2 years.

cricket20 [7]

Answer:

83.125 pounds of potatoes

Step-by-step explanation:

1. Divide 1,312 by 2

1,312/2 = 665

This means that in 1 year 8 people ate 665 pounds of potatoes.

2. Divide 665 by 8

665/8 = 83.125

This means that in 1 year 1 person ate 83.125 pounds of potatoes.

3. In the figure below, E is on AD and C is on BD. The dimensions given are in meters. What is the length, in meters, of CD?

damaskus [11]

Answer:

C. 3,960

Step-by-step explanation:

∆ADB ~ ∆EDC. Therefore,

$\frac{AB}{EC} = \frac{DB}{DC}$

$\frac{2,000}{1,200} = \frac{2,640 + x}{x}$ (substitution)

Solve for x

$\frac{5}{3} = \frac{2,640 + x}{x}$

Cross multiply

$5*x = 3(2,640 + x)$

$5x = 7,920 + 3x$

5x - 3x = 7,920

2x = 7,920

x = 7,920/2

x = 3,960 meters
