The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.



How much does an ounce of the chemical cost in 2005? (Do NOT type the $ with your answer.)

The diagram of x + 3 and 2x are as drawn in the image attached

Given the situations: x = 1, x = 2, x = 3 and x = 4

For  x + 3

x = 1, x+3 = 4

x = 2, x+3 = 5

x = 3, x+3 = 6

x = 4, x+3 = 7

For  2x

x = 1, 2x = 2

x = 2, 2x = 4

x = 3, 2x = 6

x = 4, 2x = 8

You will use the values of x and y = x+3, and the values of x and y = 2x to draw the diagram of the lines as shown in the attached image

GO IN REVERSE

24 x2= 48

48/8=6

now you have the 2 side you need to use Pythagoras

6^2+8^2=100

square root of 100=10cm

so the hypotenuse is 10 cm

Answer:

x = 21

y = 15

Step-by-step explanation:

Exterior angles on the same side of the transversal are supplementary

So, 3x - 16 + 6x + 7 = 180

9x -9 = 180

9x = 189

x = 21

11y - 32 = 6x + 7 since the angles are vertical angles

11y - 32 = 6(21) + 7

11y - 32 = 126 + 7 = 133

11y = 165

y = 15

Answer:

(-1,-3)

Step-by-step explanation:

Substitute y=x-2 into y=4x+1

x-2=4x+1

substract -1 on both sides.

x-3=4x

subtract x on both sides

-3=3x

divide by 3 on both sides

x=-1

Substitute -1 into equation

y=x-2

y=(-1)-2

y=-3

So it would be (-1,-3)

The x and y value from the given system of equations are 7 and -3 respectively.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

The given simultaneous equations are 3x-2y=27 ------(I) and 3x-y=24 ------(II) .

Subtract equation (I) from (II), we get

3x-y-(3x-2y)=24-27

⇒ y=-3

Substitute y=-3 in equation (I), we get

3x-2(-3)=27

⇒ 3x=21

⇒ x=7

Therefore, the x and y value from the given system of equations are 7 and -3 respectively.

Answer:

rug long = 34 ft

rug wide = 17 ft

Step-by-step explanation:

given data

wide = 18 ft

long = 35 ft

area of carpet  = 528 ft

solution

we get here area of floor that is

and we consider length of carpet = 35 - 2x

and width = 18 - 2x

(35 - 2x) × (18 - 2x) = 528      ...................1

solve it we get

x = 25.5 and x = 1

we choose 1 ft. as the width of the strip

so rug long = 35 - 1  = 34 ft

and rug wide = 18 - 1 = 17 ft
