Answer:

y=-4x+5

Step-by-step explanation:

Answer:

y=4,000x+50,000

Step-by-step explanation:

Where y = total salary

x = number of years worked

The relationship between salary and the number of years working at the company is 50000 + 4000x

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Gabriella was offered a job after college earning a salary of $50,000.

She will get a raise of $4,000 after each year working for the company.

let the number of years worked be x.

Then, relationship between salary and the number of years working at the company is 50000 + 4000x

Answer:

15 cm squared

area =l x w

so 3 x 5= 15

Step-by-step explanation:

Answer:

15cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

Supplementary angles add up to 180°.

“θ is 148° more than its supplement”

Supplement of θ = 180°-θ

θ = (180°-θ) + 148°

2θ = 328°

θ = 164°

Supplement of θ = 180°-164° = 16°

Answer:

[tex] 50.2 \: {units}^{2} [/tex]

Step-by-step explanation:

Area of the shaded region = Area of exterior circle with radius (3 +2 = 5) units - Area of interior circle with radius 3 units

[tex] = \pi {(5)}^{2} - \pi {(3)}^{2} \\ \\ = \pi( {(5)}^{2} - {(3)}^{2} ) \\ \\ = 3.14 \times (25 - 9) \\ \\ = 3.14 \times 16 \\ \\ = 50.24\\ \\ \approx 50.2 \: {units}^{2} [/tex]

Answer:

perimeter of this figure is = 54 cm

and area of traingle is = 1/2*base *height

so = 1/2*8*6

=. 24cm*cm

and area of rectangle = length * breadth

area = 112cm*cm

so total area = 112+ 24 = 136cm*cm

Answer:

138 cm^2 = Area .          54 cm = Perimeter

Step-by-step explanation:

Find the area of the triangle-                                   b * h = A

                                                                                     2

                                                                                   8 * 6 = A

                                                                                      2

                                                                                   48/2 = A

                                                                                     24 = A

Find the area of rectangle-                                        l * w = A

                                                                                   16 * 7 = A

                                                                                      112 = A

Add the areas together.                                            24 + 112 = 136 cm^2

Perimeter is adding up all the sides.                         s + s + s + s + s

                                                                                   16 + 7 + 8 + 10 + 13 = 54 cm

Answer:

6

Step-by-step explanation:

Using the similarity theorem f the triangle

(4+6)/x+9 = 4/x

10/x+9 = 4/x

Cross multiply

10x =4(x+9)

10x = 4x+36

10x-4x = 36

6x = 36

x = 6

Hence the value of x is 6

Answer:

Total after tax and discount is $7.78

Step-by-step explanation:

(10.49×0.3)= 3.15

10.49 - 3.15 = 7.34

(7.34×0.06)= 0.44

7.34 + 0.44 = 7.78

Answer:

I mean I think they are all quadrilateral, but the one that is congruent and perpendicular on both sides is a square.

Step-by-step explanation:

Answer:

Bob is at the top, so he starts at step 9.

Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)

Sue climbs from one step on one step.

Then she if she climbs n times, she will be at the step number:

S(n) = 0 + 1*n

And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:

B(n) = 9 - 2*n

We want to see when they meet, then we need to solve:

S(n) = B(n)

1*n = 9 - 2*n

1*n + 2*n = 9

3*n = 9

n = 9/3 = 3

n = 3.

This means that they meet a the step:

S(3) = 3*1 = 3

B(3) = 9 - 2*3 = 9 - 6 = 3

They meet at the third steep.
