I cannot figure this question out

Mathematics
1 answer:
uysha [10]3 years ago
5 0

Answer:

1/12

Step-by-step explanation:

you need to make sure that they have a common denominator before doing anything.

Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)

So then, put 12 as both denominators, and subtract.

7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.


Sorry if this is confusing, i tried explaining as best i could! Hope this helped!

Find an equation for the line that passes through the points (-2,-6) and (6,-4)
JulsSmile [24]
Slope of line
m= (y2-y1)/(x2-x1)
=(-4--6)/(6--2)
=2/8
=1/4

Line in two point form
(y-y1)=m(x-x1)
y--2=(1/4)(x-6)
y+2=(1/4)(x-6)
simplify
4(y+2)=x-6 =>
x-4y-14=0
Alternatively, use the slope intercept form:
y--2=(1/4)(x-6) =>
y=(1/4)x - 3/2-2 =>
y=(1/4)x -7/2

Solve linear equations <br><br> Solve for x <br><br> -2(4x + 3) = 3(x + 1)
inna [77]

Answer:

x = - \frac{9}{11}

Step-by-step explanation:

Given

- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides

- 8x - 6 = 3x + 3 ( subtract 3x from both sides )

- 11x - 6 = 3 ( add 6 to both sides )

- 11x = 9 ( divide both sides by - 11 )

x = - \frac{9}{11}
