Answer:

y=−2/3x+8/3

Step-by-step explanation:

2x+3y=8

Step 1: Add -2x to both sides.

2x+3y+−2x=8+−2x

3y=−2x+8

Step 2: Divide both sides by 3.

3y/3=−2x+8/3

y=−2/3x+8/3

Y=3(2)^x what is the y intercept the x intercept and is the graph increasing or decreasing

TEA [102]

This is an exponential function, with base 2. Since 2 is greater than 1, the function is increasing.

For the y intercept, we have to set $x=0$ , and we have

$y=3\cdot 2^0=3\cdot 1=3$

For the x intercept, we have to set $y=0$ and solve for x:

$3\cdot 2^x=0\iff 2^x=0$

And this has no solution. All we can say is that

$\displaystyle \lim_{x\to-\infty}2^x=0$

So, the x axis is an asymptote for the function, but the graph neves crosses it.

Fine the distance between (-8, 4) and (-8, -2)

zubka84 [21]

Answer:

The distance between the two points is six units.

Step-by-step explanation:

We are given two coordinate pairs:

(-8, 4)
(-8, -2)

With these, we can find the distance between the two using the distance formula. The distance formula is:

$\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, \ \text{where d is the distance.}$

Additionally, we need to label our coordinates. In math, coordinates are labeled as (x₁, y₁) and (x₂, y₂).

Therefore, our coordinate pairs can be labeled in this format.

(-8, 4)

x₁ = -8
y₁ = 4

(-8, -2)

x₂ = -8
y₂ = -2

Now, we can substitute these values into the formula and solve for d.

$\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d = \sqrt{(-8 - -8)^2 + (-2 - 4)^2}\\\\d = \sqrt{(0)^2+(-6)^2}\\\\d = \sqrt{0 + 36}\\\\d = \sqrt{36}\\\\d = 6$

Therefore, the distance between the two points is six units.
