Comeplete the following : Rx0 Do2 : (2,4) -> (-4, 8) (4, -8) (-4, -8)

1 answer:

6 0

Point (2, 4) was reflected over the x axis to give (2, -4). It was then dilated by a scale factor of 2 to get (4, -8). Hence (2, 4) ⇒ (4, -8)

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>reflection, translation, rotation and dilation.</em>

Translation is the movement of a point either<em> up, down, left or right</em> on the coordinate plane.

Point (2, 4) was reflected over the x axis to give (2, -4). It was then dilated by a scale factor of 2 to get (4, -8). Hence (2, 4) ⇒ (4, -8)

Graph the linear equation 6x-2y=12

Bezzdna [24]

Subtract both sides from 6x, leaving you with the equation:

-2y=-6x+12

Now, you divide all of the sides by -2, therefore leabing you with the equation:

y=3x-6

Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.

cupoosta [38]

Answer:

$y=x+8$

Step-by-step explanation:

Slope of straight line can be calculated as

$m=\frac{y_2-y_1}{x_2-x_1}$

Here $(x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)$

$m =\frac{10-5}{2-(-3)}\\m=1$

Equation of straight line in slope intercept form is

$y-y_1=m(x-x_1)\\y-5=(x+3)$

$y=x+8$

Jeff and Kirk can build a 75-ft retaining wall together in 4 hours. Because Jeff has more experience, he could build the wall

oee [108]

It will take Kirk about 8 hours 32 minutes to build the wall by himself.

<h3>What is Quadratic Polynomial?</h3>

Quadratic equations are second-degree algebraic expressions and are of the form ax² + bx + c = 0.

Here, Let k represent Kirk's time (in hours) to build the wall by himself. Then (k-1) is the time it takes for Jeff to build it. Their working-together rate in "walls per hour" is ...

1/k +1/(k -1) = 1/4

Multiplying by 4k(k-1), we have ...

4(k-1) +4k = k(k -1)

k² -9k = -4 . . . . . . . . subtract 8k and simplify

k² -9k +20.25 = 16.25 . . . . . add (9/2)² to complete the square

k -4.5 = √16.25 . . . . . . . . . take the square root

k = 4.5 +√16.25 ≈ 8.531129 . . . hours

The fractional hour is ...

0.531129 × 60 min ≈ 31.9 min ≈ 32 min

Thus, It will take Kirk about 8 hours 32 minutes to build the wall by himself.
