Answers

Answer:

x = 5

Step-by-step explanation:

4x-3=2x+7

Subtract 2x from each side

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

2x-3 = 7

Add 3 to each side

2x-3+3 = 7+3

2x = 10

Divide by 2

2x/2 = 10/2

x = 5

add 3 to the other side

Answer:

where is the graph itself?

Answer:

  see below

Step-by-step explanation:

Pre-image: A(3, 8), B(3, 3), C(7, 3)

Reflection in the x-axis changes the y-coordinate sign:

  A'(3, -8), B'(3, -3), C'(7, -3)

Reflection in the y-axis changes the x-coordinate sign:

  A''(-3, -8), B''(-3, -3), C''(-7, -3)

__

Comment

We have assumed that the first image is reflected again to get the second image. If the second image is supposed to be a reflection of the pre-image, then only the sign of x will change from the pre-image coordinates.

There are no "rotated" images; only reflected ones. (Though, after the second reflection, the image could be considered to be a 180° rotation of the pre-image.)

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points
(2, -1) and (10, 7).

y =
x+

Answers

Answer:

y = ✔ 1x+ ✔ -3

Step-by-step explanation:

The equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

What is the point slope form of the equation of a line?

The point slope form of a line is given by -

y - y₁ = m(x - x₁)

Given is a line that passes through the points (2, -1) and (10, 7).

The point - slope form of a line is given by the general equation -

y - y₁ = m(x - x₁)

We will find the slope of the line as follows -

m = (7 + 1)/(10 - 2) = 8/8 = 1

The line passes through the point (2, -1), so we can write the equation of line as -

y - (- 1) = x - 2

y + 1 = x - 2

x - y = 3

y =  x - 3

Therefore, the equation of the line passing through the points (2, -1) and (10, 7) is y =  x - 3.

After learning how to fly, Wendy reduced her daily commute time by 75% Previously, her commute took m minutes. Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly? Help guys i don't know

Answers

Answer:

Given:

(i) Wendy reduced her daily commute time by 75% by learning how to fly.

(ii) Previously, it took her 'm' minutes to commute.

To find:

(i) Wendy's commute time in minutes after she learned how to fly.

Solution:

Given that earlier it took Wendy 'm' minutes to commute.

After learning how to to fly, the commute time reduced by 75%.

So, time taken now = (100-75)% of previous time

= 25% of 'm' minutes

= \frac{25m}{100}

100

25m

= \frac{m}{4}

So, the time taken by Wendy now is \frac{m}{4}

-6x - 7y = -10 ...2

...2 × 2 in 2 sides of the equation

-12x -14y = -20 ...3

...1 + ...3

8x + 14y +(-12x -14y) = 4 +(-20)

8x + 14y - 12x -14y = 4 - 20

-4x = -16

x = (-16)/(-4)

Edwin and Anthony are building a rectangular deck in their backyard. The longer side is 2 ft more than 1/3 of the perimeter. The shorter side is 1/10 of the perimeter. They also know that the longer side is 9 ft longer than the shorter side. What is the perimeter of the deck?

Answers

Answer:

30 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Let

Perimeter = x

Length = 1/3x + 2

Width = 1/10x

Length = 9 + 1/10x

Perimeter of the deck = 2(length + width)

x = 2(1/3x + 2 + 1/10x)

x = 2(10x+3x/30 + 2)

x = 2(13/30x + 2)

x = 26/30x + 4

x - 26/30x = 4

30x-26x/30 = 4

4/30x = 4

Divide both sides by 4/30

x = 4 ÷ 4/30

= 4 × 30/4

x = 30 ft

Length = 1/3x + 2

= 1/3(30) + 2

= 30/3 + 2

= 10 + 2

= 12 ft

Width = 1/10x

= 1/10(30)

= 30/10

= 3 ft

Length = 9 + 1/10x

= 9 + 1/10(30)

= 9 + 30/10

= 9 + 3

= 12 ft

The perimeter of the deck = x = 30 ft
