2x-3y=2 for graphing systems of linear equations

Mathematics
1 answer:
Galina-37 [17]3 years ago
7 0

Answer:

-2/3 is the y intercept

Step-by-step explanation:

So to find the y-intercept you must first put this in Slope-intercept form, I believe the form it is in right now is called standard form.

To get it into slope intercept form, we have to isolate y:

subtract 2x from both sides:

-3y = -2x + 2

Divide both sides by -3:

y = (2/3)x - 2/3

Now that we have slope-intercept form, we can find the y-intercept. We know slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case the y-intercept is -2/3.

Hope this helps!

How do I solve this problem ​
Vaselesa [24]
C = 84 degrees

A = 2B
C = A + 20
A + B + C = 180

A = 2B
A/2 = B

A + (A/2) + (A+20) = 180
multiply each side by 2
2A + A + 2A + 40 = 360
combine like terms
5A + 40 = 360
subtract 40 from both sides
5A = 320
divide both sides by 5
A = 64

C = A + 20
C = 64 + 20
C = 84

What is the vertex of<br> f(x) = 2(x - 5)2 + 12
alexira [117]

Answer:

The vertex is (5, 12)

Step-by-step explanation:

The vertex, from vertex form, is (h,k).

Vertex form is a(x - h)² + k

= 2(x - 5)² + 12

So h = 5, k = 12

The vertex is (5, 12).

I hope this helped!
