Answer:

Step-by-step explanation:

$-12u-\left(-11u\right)-4u+7u-5u=14\\\\\mathrm{Apply\:rule}\:-\left(-a\right)=a\\-12u+11u-4u+7u-5u=14\\\\\mathrm{Add\:similar\:elements:}\:-12u+11u-4u+7u-5u=-3u\\-3u=14\\\\\mathrm{Divide\:both\:sides\:by\:}-3\\\frac{-3u}{-3}=\frac{14}{-3}\\\\Simplify\\u=-\frac{14}{3}\\\\u = -4\frac{2}{3}$

2-8x=10 looking for solution

leva [86]

Answer:

Step 1: Simplify both sides of the equation.

2−8x=10

2+−8x=10

−8x+2=10

Step 2: Subtract 2 from both sides.

−8x+2−2=10−2

−8x=8

Step 3: Divide both sides by -8.

−8x ÷ −8

=

8 ÷ −8

x=−1

Answer:

x=−1

Kevin can walk 14 miles in 5 hours. How far can he walk in 3 1/2 hours?

Anton [14]

Step-by-step explanation:

If he can walk 14 miles in 5 hours, take 14÷5 to find out how long he can walk in 1 hour. (2.8)

Then take 2.8 miles times 3.5 hours is 9.8 miles

HELPPP ITS AN EMERGENCY!!!!!!

Answer:

The equation in point-slope is $\mathbf{y+5=3(x-6)}$

Step-by-step explanation:

We need to write the point-slope form of the equation of the line passing through the point (6,-5) and perpendicular to the line $y=-\frac{1}{3}x+4$

The general form of point-slope is; $y-y_1=m(x-x_1)$

where m is slope and $(x_1,y_1)$ is the point

We need to calculate slope.

We are given equation of line $y=-\frac{1}{3}x+4$ that is perpendicular to the required line.

The equation is given in slope-intercept form $y=mx+b$ where m is slope.

Comparing both equations we get m= -1/3

But we know that when lines are perpendicular their slopes are opposite reciprocal of each other i.e $m=-\frac{1}{m}$

<em>So, </em><em>slope of required line is m = 3 </em><em>(opposite reciprocal of -1/3)</em>

Now, the equation in point-slope form having slope m=3 and point (6,-5) is

$y-y_1=m(x-x_1)\\y-(-5)=3(x-6)\\y+5=3(x-6)$

So, The equation in point-slope is $\mathbf{y+5=3(x-6)}$
