Answer:

$x = -\frac{1}{3}$

Step-by-step explanation:

1/2 = 2/4
Plug 2/4 in: -3/4x + 2/4 = 3/4
Subtract 2/4 from each side, so it now looks like this: -3/4x = 1/4
Divide each side by -3/4, so it cancels out the -3/4 next to x. It should now look like this: x = -1/3

I hope this helps!

Answer:

The line equation in slope-intercept form is:

$y\:=-\frac{2}{5}x+4$

Hence, option D is true.

Step-by-step explanation:

Given the points

(0, 4)

(5, 2)

Finding the slope between the points

$\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{2-4}{5-0}$

$m=-\frac{2}{5}$

As the y-intercept is obtained by setting the value x = 0.

As we know that when x = 0, the vale of y-intercept y = 4

so the y-intercept is b = 4.

As the slope-intercept form is

substituting the slope m = -2/5 and the y-intercept b=4

$y = mx+b$

$y\:=-\frac{2}{5}x+4$

Therefore, the line equation in slope-intercept form is:

$y\:=-\frac{2}{5}x+4$

Hence, option D is true.

Ž + 1 = 9<br> Ox = 16<br> x = 20<br> Ox = 4<br> Ox=5

kotykmax [81]

Answer:

x = 16

Step-by-step explanation:

-- = 9-1 ...... first shift 1 and it will be -1

x = 8 ....... secondly 9-1 =8

x = 16 ..... criss cross and 2×8 = 16

there fore the value of x is equals to 16.

you can check it!

Charlotte is driving at 52.7 mi/h and receives a text message. She looks down at her phone and takes her eyes off the road for 4

Answer:

385.7 ft

Step-by-step explanation:

The relation between speed, distance, and time is ...

distance = speed × time

<h3>Compatible units</h3>

The speed is given in miles per hour, but the time is given in seconds and the distance is wanted in feet. This suggests a conversion of speed to feet per second is appropriate.

$\dfrac{52.7\text{ mi}}{\text{h}}\times\dfrac{1\text{ h}}{3600\text{ s}}\times\dfrac{5280\text{ ft}}{1\text{ mi}}=\dfrac{52.7\cdot22\text{ ft}}{15\text{ s}}=77.29\overline{3}\text{ ft/s}$

<h3>Distance</h3>

The distance traveled is the product of this speed and the time period.

$\dfrac{77.29\overline{3}\text{ ft}}{1\text{ s}}\times4.99\text{ s}=385.6937\overline{3}\text{ ft}\approx\boxed{385.7\text{ ft}}$
