Answer:

g(-2) = 4

Step-by-step explanation:

g(x)=−4x−4

Find g(-2)

This means let x = -2

g(-2)=−4(-2)−4

       = 8 -4

       = 4

Answer:

B. A water wheel in a dry river

Step-by-step explanation:

Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.

i.e Work done = Force x distance

It is measured in Joules.

Also, the work done by an object could be a measured of potential energy.

So that,

Work done = potential energy = mass x gravitational force x height

Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.

Answer:

1:4

Step-by-step explanation:

There are only two colours available, red and green.  We know that there are 11 red marbles and 55 marbles altogether, so the number of green marbles must be 55 - 11, or 44.  That means that the ratio of red to green marbles is 11:44, or 1:4.

Answer:

Multiply=times top then bottom. 1/2*1/3=1*1/2*3=1/6

Divide Fractions=take reciprocal then multiply. 1/2=1/3=1/2*3/1=3/2

Step-by-step explanation:

Not needed

Answer:

B

Step-by-step explanation:

3 5/5 = 4 because 5/5 is equal to 1, and 3+1 = 4.

1/4 is not equal to 4 because it is equal to 0.25

4/1 = 4 because it is an identity

3 4/4 = 4 because 4/4 is equal to 1, and 3+1 = 4

Answer:

$10.30

Step-by-step explanation:

X = 49.95 - (24.65 + 15)

x = 49.95 - 39.65

x =   10.30

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

The price of silver has increased by 25% per year from 2000. In the year 2000, Harry bought a silver bowl for $170.

To calculate the price of the silver bowl after x years, we need to use the following formula:

F(x)= PV*(1+g)^x

F(x)= future value

PV= present value

g= growth rate

x= number of years

For example, we determine the value of the coin after 10 years:

F(x)= 170*(1.25^10)

F(x)= $1,583.25

Answer:

F(x)= 170*(1.25^10)

F(x)= $1,583.25

Answer:

i thinks or might be the correct

Answer:

The correct answer is [tex]\frac{or}{and} \\[/tex].

Step-by-step explanation:

Part 1: The sign "<" means "less than." Therefore, "or" makes the most sense because there is only one option if you use this sign:  the number on the left has to be smaller than the number on the right.

Part 2: The sign [tex]\leq[/tex] means "less than or equal to." Therefore, "and" makes the most sense because there are two options if you use this sign: the number on the left can be either smaller than or equal to the number on the right.

Therefore, the correct answer is [tex]\frac{or}{and} \\[/tex].

Hope this helps! :D

Answer: D) 26.1

Step-by-step explanation:

Answer:

18 is the minimum value.

Step-by-step explanation:

Set up an equation:

13 [tex]\leq[/tex] x - 5

Add 5 on both sides to isolate x:

(13) + 5 [tex]\leq[/tex] (x - 5) + 5

18 [tex]\leq[/tex] x

X can be equal to or greater than 18 so the minimum value of the number is 18.

Hope this helps!

Answer:

G. 4n-5< -21

Step-by-step explanation:

because....I'm smart

Answer:

The equation is:

y = 7x + 5

Step-by-step explanation:

Given

Figure 0 = 5 tiles

Figure 1 = 5+7 = 12 tiles

Given that it adds 7 titles in each figure. Thus, the rate of change = 7 tiles

Thus, the equation is:

y = 7x + 5

Here

VERIFICATION:

setting x = 0 to determine the tiles in figure 0

y = 7x + 5

y = 7(0) + 5

y = 5

Thus, the figure 0 has 5 tiles

setting x = 1 to determine the tiles in figure 1

y = 7x + 5

y = 7(1) + 5

y = 7 + 5

y = 12

Thus, the figure 0 has 12 tiles    (5 plus 7 added)

Answer:

15.68%

Step-by-step

Since 44% of the 28% play sport subtract 44 from 100 to see how many of the 28% do not play sports and you get 56%. So multiply 56% and 28% and you get 15.68%.

Answer:

n = -1

Step-by-step explanation:

please mark me brainliest

Answer:

n = -1

Step-by-step explanation:

7 (n + 4) = 21

28 + 7n = 21

28 + -28 + 7n = 21 - 28

7n = -7

n = -1
