Complete part (a) and part (b) given the following system of equations x-y=0 2x + 3y = -5 Solve this system graphically.​

Answers

Answer 1

Answer:

(-1, -1)

Step-by-step explanation:

x - y = 0      ------>     x = y

2x + 3y = -5

2(y) + 3y = -5

5y = -5

y = -1

x - (-1) = 0

x = -1

The solution to this system is (-1, -1). To solve graphically, plot both functions and you will see that they intersect at (-1, -1).

I hope this helps!

Enter your answer in the box

Answers

Answer:

389.017 cm³

Step-by-step explanation:

Given:

Side length of cube = 7.3 cm

The volume of a cube is the cube of the side length.

V = (side length)³

Substitute the side length of the cube to determine the volume of the cube.

⇒ V = (s)³

⇒ V = (7.3)³

⇒ V = (7.3)(7.3)(7.3) = 389.017 cm³

Step-by-step explanation:

10 white squares

15 shaded squares

5b.

a1 = 1 = 2×1 - 1

a2 = a1 + 2×2 - 1 = 2×1 - 1 + 2×2 - 1 = 2×(1+2) - 2

a3 = a2 + 2×3 - 1 = 2×(1+2+3) - 3

...

an = 2×(1+2+...+n) - n = 2×n×(n+1)/2 - n = n²

so,

a350 = 350² = 122,500

figure350 has 122,500 squares.

a1 = 1

a2 = a1 = 1

a3 = a2 + 5

a4 = a3 = 6

a5 = a4 + 9

a6 = a5 = 15

a7 = a6 + 13

a8 = a7 = 28

...

a(2n) = a(2n - 1)

a(2n - 1) = a(2(n-1) - 1) + 1 + 4(n - 1) = n×1 + 4(0+1+2+...+n-1) =

= n + 4×(n-1)×n/2 = n + 2×(n² - n) = 2n² - n

therefore,

a350 = a349

a349 = a(2×175 - 1) = 2×175² - 175 = 61,075

figure350 has 61,075 shaded squares.

three different purposes for determining the derivative.

Answers

Answer:

A derivative is a slope function. If you want to find the slope anywhere along the function, you can.

Explanation:

Given: What is the purpose of a derivative?

A derivative is a slope function: m=f'(x=value). If you want to find the slope anywhere along the function, you can.

If you want to find a tangent line at a specific point along the function you can, using the slope and the point: y−y1=m(x−x1)

Answer:

See below

Step-by-step explanation:

A derivative is a slope function, so it allows you to find the slope anywhere along a function where it's continuous.

For example, the derivative of velocity is acceleration, which is applicable in real life.

You can also find a tangent line at a specific point by finding the slope of the function at that point and then using point-slope form [tex]y-y_1=m(x-x_1)[/tex] to get your tangent line.

Mr. Jones is building the garage shown below. What is the volume of the garage?

Answers

Answer: 891 ft³

Step-by-step explanation:

     We can break the garage into two different parts. The roof, triangular, and the rest, rectangular. I will start by solving for the rectangular part.

     V = L * W * H

     V = 12 ft * 9 ft * 7.5 ft

     V = 810 ft³

     Now, I will solve for the triangular part, the roof. First, 9 ft - 7.5 ft = 1.5 ft, so the height of just the roof is 1.5 ft.

     V = [tex]\frac{L * W * H}{2}[/tex]

     V = [tex]\frac{12 * 9* 1.5}{2}[/tex]

     V = [tex]\frac{162}{2}[/tex]

     V = 81 ft³

     Lastly, I will add the two different parts together.

810 ft³ + 81 ft³ = 891 ft³
