Answer:

x  = 4

Step-by-step explanation:

We can find the answer to this by solving the equation:

3x - 4 = 8

3x - 4 + 4 = 8 + 4

3x = 12

x  = 4

Rewrite 3x + 4y = 10 using function notation
Contact [7]
A function notation is expressed as f(x) = ax^b + cx^d + ..... where f(x) is equal to y, In this case, to r<span>ewrite 3x + 4y = 10 using function notation, we rearrange the statement and express in terms of x only. Hence

4y = 10 - 3x
y = (10 - 3x) /4 = f(x)
f(x) = 2.5 - 0.75x</span>

A chest is filled with toy blocks. Each block has a volume of 1 cubic foot. Twenty-five blocks fit in the bottom of the chest an
Mice21 [21]

Answer:

The correct answer is 75 cubic feet.

Step-by-step explanation:

Volume of each block of cube is 1 cubic foot. Since the block is of the shape of a cube, the side length is 1 foot.

Number of blocks needed to fill the bottom of the the chest is 25.

Height of the chest is 3 feet.

Therefore there are three layers to be filled by blocks. Each layer needs 25 blocks each. Thus number of blocks needed to fill the whole chest is 25 × 3 = 75.

Volume of 75 blocks = Volume of the chest = 75 × 1 = 75 cubic feet.

Therefor the volume of the chest is given by 75 cubic feet.

Find the equation of the line. Write the equation using function notation. Through (-3,-9); parellel to 5x+3y=8
mihalych1998 [28]

Answer:

The equation of a parallel line in point-slope form would be f(x) = -5/3x - 14

Step-by-step explanation:

To find this, we must first find the slope of the original line. We can do this by solving for y.

5x + 3y = 8

3y = -5x + 8

y = -5/3x + 8/3

Now that we have the slope of the original line, we can use the point and slope and put them into the base form of point-slope form. Then we solve for y to get the final result.

y - y1 = m(x - x1)

y + 9 = -5/3(x + 3)

y + 9 = -5/3x - 5

y = -5/3x - 14

Then to get the function notation, we need to replace the y with f(x).

f(x) = -5/3x - 14

Answer:

H) 45,000 + 2,500 x = 54,000 + 1,500x

Step-by-step explanation:

Let the number of years be represented as x

For Jerry

Jerry has a new job and earns a salary of $45,000.Jerry will receive a salary increase of $2,500 per year,

The equation is

45,000 + 2,500x

Victoria has a new job and earns a salary of $54,000. and Victoria will receive a salary increase of $1,500 per year.

The equation is :

54,000 + 1,500x

The equation that can be used to find x, the number of years it will take Jerry to earn the same salary as Victoria is given as

Equation for Jerry = Equation for Victoria

45,000 + 2,500x = 54,000 + 1,500x

Option H is the correct option
