hi

Answer:

slope = 2

y-intercept = (0,-3)

Answer: Rearrange the equation to get m= 1/2, b= 3/2

Step-by-step explanation:

Given :

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers  cost $0.05 each.

To Find :

How much would Mrs. Algebra's single order be.

Solution :

Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.

T = $(0.10 + 0.49 + 12.99 + 0.05)

T = $13.63

Therefore, Mrs. Algebra's single order cost is $13.63 .

Hence, this is the required solution.

Complete question is;

Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall. Decide whether each of the crate sizes described below has the same volume as Justin’s crate.

a. 9 feet long, 1 foot wide, 4 feet tall

b. 8 feet long, 2 feet wide, 2 feet tall

c. 4 feet long, 4 feet wide, 3 feet tall

d. 8 feet long, 3 feet wide, 3 feet tall

e. 6 feet long, 2 feet wide, 4 feet tall Answer:

Options C & E have the same volume as Justin's crate.

Step-by-step explanation:

We are told Justin has a crate that is 8 feet long, 2 feet wide, and 3 feet tall.

Thus, original volume is;

V_o = 8 × 2 × 3 = 48 ft³

A) For a dimension of 9 feet long, 1 foot wide, 4 feet tall , volume is;

V_a = 9 × 1 × 4 = 36 ft³

B) For a dimension of 8 feet long, 2 feet wide, 2 feet tall, volume is;

V_b = 8 × 2 × 2 = 32 ft³

C) For a dimension of 4 feet long, 4 feet wide, 3 feet tall, volume is;

V_c = 4 × 4 × 3 = 48 ft³

D) For a dimension of 8 feet long, 3 feet wide, 3 feet tall, volume is;

V_d = 8 × 3 × 3 = 72 ft³

E) For a dimension of 6 feet long, 2 feet wide, 4 feet tall, volume is;

V_e = 6 × 2 × 4 = 48 ft³

Looking at all the options, the only ones that given a volume equal to Justin's original volume are options C & E.

Answer:

x=8

Step-by-step explanation:

5x+6+134=180

5x=40

x=8

Answer:

numbro 4

Step-by-step explanation:

Answer:

4x

Step-by-step explanation:

the -8 and +8 cancel out

x and 3x are both positive so add them

you're left with 4x

Simplifying is the same as solving this question. I'll give steps instead.

x - 8 + 3x + 8

x + 3x - 8 + 8       (Arrange the equation)

(x + 3x) (- 8 + 8)   (Parentheses the like terms together)

(4x) (0)                 (Solve)

4x                        (Simplified)

Answer:

3750

Step-by-step explanation:

Simple interest (I) is calculated as

I = [tex]\frac{PRT}{100}[/tex] ( P is the principal, R is rate of interest and T time in years )

Here P = 25000, R = 5 and T = 3 , thus

I = [tex]\frac{25000(5)(3)}{100}[/tex]

  = [tex]\frac{375000}{100}[/tex]

  = 3750

Answer:

Answer:

[tex]f(x)=6x[/tex] is a direct variation.

Step-by-step explanation:

Given the function

[tex]f(x)=6x[/tex]

We have to determine whether the equation [tex]y=6x[/tex] is a direct variation or not.

As we know that in direction variation, y and x increase or decrease by the same factor by the formula

[tex]y=kx[/tex]

where 'k' is the constant of variation

Given the function

[tex]y=6x[/tex]

Here 6 is the constant of variation            ∵ [tex]y=kx[/tex]

Also y and x increase and decrease by the same factor

For example,

when x=6, y = 6(x)=6(6)=36

when x=8, y = 6(x) = 6(8) = 48

Hence, when x increase, the y increases by the same factor.

Therefore, [tex]f(x)=6x[/tex] is a direct variation.

$20.70

Step-by-step explanation:

15% of 18 is 2.7 so 18 + 2.7 = 20.70

Answer:

C = 94

Step-by-step explanation:

Say the centre point is Y, then the triangle BCY is an isosceles, therefore angle BCY = angle CBY

So the base points of that triangle are both 47, to find the angle of BYC, you just do:

180 - 47 - 47 = 86

and then since x is on a line with 86, and angles on a straight line add up to 180:

180 - 86 = 94

answer is 94 degrees

94
