I think I’m not positive but it would be y8

If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.

Percent change of 1/3 to 2/3 step by step pls.

sesenic [268]

1/3 percentage is 0.33% i just got that by dividing 1/3
2/3 percentage is 0.66% i got that the same way.
basically the difference the percentage between the two fractions is double

Stuck! Help please!!

devlian [24]

<h3>Answer: x = -1</h3>

Explanation:

The given quadratic is in the form y = ax^2 + bx + c

We have a = 1, b = 2, c = 2

This then leads to

h = -b/(2a)

h = -2/(2*1)

h = -1

This is the x coordinate of the vertex (h,k)

The axis of symmetry is the vertical line passing through the vertex. So it must share the x value in question.

Meaning the axis of symmetry is x = -1. Every point on this vertical line has an x coordinate of -1. This line of symmetry splits the parabola into two equal mirrored halves.

I recommend using a graphing tool like Desmos to visually confirm the answer.

The graph of an exponential function passes through (2,−32) and (3,−64). Find the exponential function that describes the graph.

Greeley [361]

Answer: $y=(-8)2^x$

Step-by-step explanation:

The exponential function will have this form:

$y=ab^x$

We know that the function passes through the points $(2,-32)$ and $(3,-64)$ . Then, we can substitute the coordinates of the point $(2,-32)$ into $y=ab^x$ and solve for "a":

$-32=ab^2\\\\a=\frac{-32}{b^2}$

Then, we know that:

$y=(\frac{-32}{b^2})b^x$

Now, we neeed to substitute the coordinates of the second point $(3,-64)$ into $y=(\frac{-32}{b^2})b^x$ and solve for "b":

$-64=(\frac{-32}{b^2})b^3\\\\-64=-32b\\\\\frac{-64}{-32}=b\\\\b=2$

Substituting the value of "b" into $a=\frac{-32}{b^2}$ we can find "a":

$a\frac{-32}{2^2}\\\\a=-8$

Therefore, we get that the exponential function that describes the graph, is:

$y=(-8)2^x$

Which of the following points is a solution to y ≤ −2x + 3?

Alika [10]

Answer:

d; below; y = −2x + 2

Step-by-step explanation:

the equality ≤ means left to right that y is equal or less than. We see that 2 is equal or less than 3.

We check the resulting equation also and see that if we +3 it = 1 and if we +2 it equals 0 so we know +2 in answer format can be less than also. But with questions we are measuring the units and +2 is less than +3.
