Describe in detail how you would create a number line with the following points: 4, 1.25, the opposite of 3, and – (–2 fraction

of one-half). Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first.

What is the value of x in the equation 5(4x-10)+10x = 4(2x-3)+2(x-4)?<br> A)-7/4 B)-1/4 C)3/20 D)3/2
Basile [38]

Answer:

D (3/2

Step-by-step explanation:

<u>Simplify both side of the equation</u>: 5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

(5)(4x) + (5)(−10) + 10x = (4)(2x) + (4)(−3) + (2)(x) + (2)(−4)

Then you distribute: 20x + −50 + 10x = 8x + −12 + 2x + −8

(20x + 10x) + (−50) = (8x + 2x) + (−12 + −8)

Combine like terms: 30x + −50 = 10x + −20

30x - 50 = 10x - 20

<u>Subtract 10x from both sides</u>: 30x − 50 − 10x = 10x − 20 − 10x

20x - 50 = -20

<u>Add 50 to both sides</u>: 20x - 50 + 50 = -20 + 50

20x = 30

<u>Divide both sides by 20</u>: 20x / 20 = 30 / 20

<em>x = 3/2</em>

Boom! I hope that helped :)

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds
strojnjashka [21]

Answer:

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Step-by-step explanation:

we are given height equation as

h=-16t^2+25t+5

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

h=-16(1.5)^2+25(1.5)+5

we can solve for h

h=42.5-16\cdot \:1.5^2

h=42.5-36

h=6.5

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

The scale factor of dilation from ABC to A^{1} B^{1} C^{1} is 0.333.

Step-by-step explanation:

Step 1:

First, we plot the coordinates of both triangles.

The coordinates of the triangle A^{1} B^{1} C^{1} are as follows;

A^{1} = (2, 3), B^{1} = (2, 1), and C^{1} = (3, 1).

The coordinates of triangle ABC are;

A = (4, 9), B = (4, 3), and C = (7, 3).

Step 2;

Next, we need to find the distances between at least two coordinates for both triangles.

The distances between vertical lines are found by calculating the difference in y values while for horizontal lines, the distances are found by calculating the difference between the x values.

The distance of A^{1} B^{1} = 3-1=2, the distance of B^{1} C^{1} = 3-2=1.

The distance of AB =9-3=6, the distance of BC = 7-4=3.

Step 3;

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, it is the length of the AB.

So The scale factor for AB = \frac{2}{6} = \frac{1}{3} = 0.333.

The scale factor for BC = \frac{1}{3} = 0.333.
