Help Plzzzz !! Thanks

Answer 1

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = 2, 3) and (x₂, y₂ ) = (0, - 1)

m = [tex]\frac{-1-3}{0-2}[/tex] = [tex]\frac{-4}{-2}[/tex] = 2

The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = 2x - 1 → C

If the endpoints of the diameter of a circle are (6, -2)and (-6 ,2)what is the standard form equation of the circle

Answers

Answer:

[tex]x^2 + y^2 - 40 = 0[/tex]

Step-by-step explanation:

Given

[tex](h_1,k_1) = (6,-2)[/tex]

[tex](h_2,k_2) = (-6,2)[/tex]

Required

Determine the equation of the circle

First, calculate the midpoint of the given coordinates:

[tex](h,k) = \frac{1}{2}(h_1+h_2,k_1+k_2)[/tex]

[tex](h,k) = \frac{1}{2}(6-6,-2+2)[/tex]

[tex](h,k) = \frac{1}{2}(0,0)[/tex]

[tex](h,k) = (0,0)[/tex]

Next, calculate the radius.

This is the distance between [tex](0,0)[/tex] calculated above and any of [tex](6,-2)[/tex] [tex](-6,2)[/tex]

Using:

[tex](0,0)[/tex] and [tex](-6,2)[/tex], the radius is:

[tex]r = \sqrt{(0 - (-6))^2 + (0-2)^2}[/tex]

[tex]r = \sqrt{40}[/tex]

The equation is then calculated using:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where:

[tex]r = \sqrt{40}[/tex] and [tex](h,k) = (0,0)[/tex]

[tex](x - 0)^2 + (y - 0)^2 = (\sqrt{40})^2[/tex]

[tex](x )^2 + (y)^2 = 40[/tex]

[tex]x^2 + y^2 = 40[/tex]

[tex]x^2 + y^2 - 40 = 0[/tex]

A video game box is 15 inches long and 10
inches wide. If the volume of the box is 750
cubic inches, how tall is the box?
in inches

Answers

Answer:

The box is 5 inches tall

Step-by-step explanation:

The given dimensions of the video games are;

The length of the video game, L = 15 inches

The width of the video game, W = 10 inches

The volume of the video game box, V = 750 cubic inches

Assuming that the shape of the video game box is a cuboid, we have;

The formula for the volume of a cuboid, V = Length, L × Width, W × Height, H

∴ V = L × W × H

The height of the cuboid, H = V/(L × W)...(1)

Where, for the video game box;

L = Length = 15 in.

W = Width = 10 in.

V = Volume = 750 in.³

Plugging in the values of the variables in equation (1) gives;

H =  V/(L × W) = 750 in.³/(15 in. × 10 in.) = 5 in.

The height of the box, H = 5 inches.

Solve this equation:
7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

Answers

Answer:

x = 7/5

I hope this helps

Step-by-step explanation:

7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

7x - 5 -3x +2 = x -4x +5 +2x -1

4x -3 = -x +4

4x +x = 4+3

5x = 7

x = 7/5

Answer:

4 inches

Step-by-step explanation:

To solve this, use the Pythagorean Theorem: a² + b² = c². You insert the measurements you have: 3² + b² = 5² or 9 + b² = 25. To solve this, subtract 9 from both sides: b² = 16. To solve for b (length) specifically, find the square root of 16: 4.
