Answer:

x=3

Step-by-step explanation:

1/x  = (x+3)/ 2x^2

Using cross products

1*2x^2 = x(x+3)

2x^2 = x^2 +3x

Subtract x^2 from each side

2x^2 -x^2 = 3x

Subtract 3x from each side

x^2 -3x =0

Factor

x(x-3) = 0

Using the zero product property

x=0  x-3 =0

x=0   x=3

Checking the solutions

x cannot be zero since the denominator cannot be zero

x=3

How to solve 1/4 - -4/3 - -1 2/9
Ahat [919]

Answer:

2 29/36

Step-by-step explanation:

So circle the two signs., so the problem is now this:

1/4+4/3+1 2/9

Then you find the GCM, or Greatest Common Denominator.

It is 36. Then, you re-write the new answers

9/36+ 48/36+ 1 18/36

Now we have this:

1 65/36

The answer is 2 29/36

abruzzese [7]

Answer:

r=7

Step-by-step explanation:

74000=28000(1+r/12)^12(14)

divide 74000 by 28000, and cancel out 28000.

1.00580=1+r/12

(100) .06962=r

r = 6.96198

the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7

r=7

Which equation models a line that passes through point (-2,2) And has a slope of -8
trasher [3.6K]

So we will be using y=mx+b form, in which m = slope and b = y-intercept. Since we know the slope (-8), all we need to do is solve for the y-intercept. We can do this by inserting (-2,2) into the equation and solve for b.


2=-8(-2)+b


Firstly, do the multiplication: 2=16+b


Next, subtract 16 on both sides, and your answer will be -14 = b



Using the previous info we have, our equation is y = -8x - 14
