How do I find the value of x?

Mathematics
1 answer:
snow_tiger [21]3 years ago
6 0

opposite angle equal each other so:

(12x-10) = (5x+53)

add 10 to both sides

12x = 5x+63

subtract 5x from each side

7x=63

 divide both sides by 7

x = 63/7

x = 9

Find an equation of the line that (a) has the same y -intercept as the line y + 5x + 9 = 0 and (b) is parallel to the line - 3x
kap26 [50]

Equation of required line is:

y = \frac{3}{4}x-9

Step-by-step explanation:

First of all we will convert both equations in slope-intercept form

y + 5x + 9 = 0

Subtracting 5x from both sides

y+9 = 0-5x\\y+9 = -5x

Subtracting 9 from both sides

y+9-9 = -5x-9\\y = -5x-9

The y-intercept is -9.

Other equation is:

- 3x + 4y = 3

Adding 3x on both sides

-3x+3x+4y = 3x+3\\4y=3x+3

Dividing both sides by 4

\frac{4y}{4} = \frac{3x+3}{4}\\y = \frac{3}{4}x+\frac{3}{4}

As the required line has y-ntercept of line y + 5x + 9 = 0

So,

b = -9

And

The line is parallel to second line, so the slopes of both will be equal

m=\frac{3}{4}

Slope-intercept form of line is:

y=mx+b

Putting values of b and m

y = \frac{3}{4}x-9
