The pair of points lies on the same line with the given slope. Find x.<br> (4,6). (x, 12); slope = 2

uysha [10]

Answer:

x=7

Step-by-step explanation:

I got this because it is rise over run

$\frac{rise}{run} =\frac{6}{?} =2$

The missing number would be 3, and if you add that three to 4 you get 7. which means that the answer is...

(7,12)

6/x + 8/x+5 = 3<br><br> What is x

Aneli [31]

Answer:

x = -7

Step-by-step explanation:

6/x + 8/x + 5 =3

5x + 14 /x =3

Step 1: Multiply both sides by x.

5x+14=3x

5x+14−3x=3x−3x(Subtract 3x from both sides)

2x+14=0

2x+14−14=0−14(Subtract 14 from both sides)

2x=−14

−14

(Divide both sides by 2)

x=−7

Somebody help me.......

Artemon [7]

In form y=mx+b
m=slope
b=y intercept

allso
in form ax+by=c
slope=-a/b
y intercept=c/b

see each one

A.
-2x+3y=-15
slope=-(-2)/3=2/3
yint=-15/3=-5
correct

B. slope=2/3
yint=-5
correct

C. divide both sides by 6 to get to slope intercept form
y=4/5x-5
y=2/3x-5
correct

D. distribute
y+3=2/3x-2
minus 3
y=2/3x-5
correct

all of them are correct

Sales at Glover's Golf Emporium have been increasing linearly. In their third business year, sales were $155,000. This year was

Lelechka [254]

Answer:

$372,000

Step-by-step explanation:

So, first I'm going to find the equation.

The basic linear equation is y=mx+b

We know there is a difference of 5 years between 155,000 and 310,000. Subtract 155,000 from 310,000 and we get 155,000.

Divide 155,000 by 5, and we get 31,000. It increases by 31,000 every year.

Now we have y=31,000x+b.

To find b we can plug stuff in. y=sales and x=year. Im going to use the third year results.

155,000=31,000(3)+b

155,000=93,000+b

-93,000 -93,000

62,000=b

Now we have our equation <em>y=31,000x+62,000</em>.

Plus in 10 as x to find year 10"s sales and.... we get $372,000
