X+3y=0. Solve for y, then graph the equation

Mathematics
1 answer:
GalinKa [24]3 years ago
8 0

Answer:

Step-by-step explanation:

Subtract x on both sides

3y=-x

Divide both sides by 3

y=-\frac{1}{3} x

To find the y-intercept, let x = 0

y = 0, therefore the function crosses the y-axis at the origin.

To find the x-intercept, let y = 0

x = 0, therefore the function crosses the x-axis at the origin too.

The slope of the function is -1/3, from the origin, go down 1 and right 3

Clair collects seashells. At home, she has 15 shells. Every day she brings 3 back to the beach. After 5 days how many seashells
Igoryamba

The equation would be:

y = 3x + 15

1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y

2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15

3) you already defined the variables

4) 3(5)+15 = 15+15 = 30 seashells

I hope this helps!

Can someone walk me through this?
Diano4ka-milaya [45]
So you can set up proportion.

\dfrac{7.5\ \text m}{76^\circ} = \dfrac C{360^\circ}

Here, you need to solve for C.

You can do that by multiple both sides by 360 and then you should get 360^\circ\cdot\dfrac{7.5\ \text m}{76^\circ} = C \approx \boxed{35.526\ \text m}

Hope this helps.
