What is the y-intercept of 2g(x)+3x=6?
umka21 [38]

The y-intercept is basically the value of the output of the function, g(x), when x=0.

Let's replace g(x) with the variable y to make this look a bit simpler.

2y + 3x = 6

Now, we enter the value of x=0 to get the y-intercept.

2y + 0 = 6

2y = 6

Divide both sides by 2

y = 3

The value of y is 3. Now enter the values of x=0 and y=3 into point-form (x,y) to get (0,3). You should know which answer choice to choose now.

Have an awesome day!

Paraphin [41]

Answer:

An equation represents the number of pieces of lasagna that are left after dinner is \frac{1}{6}x=\frac{2}{3}

Step-by-step explanation:

Each piece of Lasagna is 1/6 of the pan

Let x be the number of pieces left

So, x pieces is \frac{1}{6}x of the pan

We are given that After dinner 2/3 of a pan of lasagna is left.

So, \frac{1}{6}x=\frac{2}{3}

x=\frac{2}{3} \times 6

x=4

So, Number of pieces left = 4

Hence An equation represents the number of pieces of lasagna that are left after dinner is \frac{1}{6}x=\frac{2}{3}

How do you solve 5/8a-27=-7
Ber [7]
First of all you need to get rid of the -27 on the left side, to do so you add 27 to both sides so it becomes:
5/8a=20
Now you can divide it by 5 to get:
1/8a=4
Now multiply it by 8 to get:
a=32

Hope this helps :)
