Find the value of Y?

Mathematics
1 answer:
aalyn [17]3 years ago
7 0
You want to do 10 + y. 'x' means multiply. So you would have to multiply. Whatever is in parenthesis is first. Unless it multiplication or division.. So add those up first then divide, then you'll get y! :)

Putting the equations in slope-intercept form changes the system from
myrzilka [38]

15x+9y=36 \rightarrow y=-\frac{5}{3}x+4 \\ \\ 10x + 6y = 36 \rightarrow y=-\frac{5}{3}x+6

The lines are parallel.

The slopes are equal.

<h2>Explanation:</h2>

The standard form of the equation of a line is given by the form:

Ax+By=C \\ \\ \\ Where: \\ \\ A \ is \ a \ positive \ integer \\ \\ B,C \ are \ integers

On the other hand, the slope-intercept form of the equation of a line is given by the form:

y=mx+b \\ \\ \\ m:Slope \\ \\ b:y-intercept

So let's convert each equation from the standard form to the slope-intercept form:

So, for the first equation:

15x+9y=36 \\ \\ Solving \ for \ y: \\ \\ 9y=-15x+36 \\ \\ y=\frac{-15x+36}{9} \\ \\ y=-\frac{5}{3}x+4

So, for the second equation:

10x + 6y = 36  \\ \\ Solving \ for \ y: \\ \\ 6y=-10x+36 \\ \\ y=\frac{-10x+36}{6} \\ \\ y=-\frac{5}{3}x+6

As you can see both equations have the same slope but different y-intercepts meaning that they are parallel. So these are the correct options:

The lines are parallel.

The slopes are equal.

Does anyone know the answer? (It's not 0,4)
Murljashka [212]
I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.
