Write the equation for the function graphed below.

Answers

Given the vertex of the parabola at point (2, -3):

The quadratic function in vertex form is:

f(x) = (x - 2)^2 - 3

where the vertex (h, k) is the minimum point = (2, -3).

The equation of the function graphed below is f(x) = a(x - 2)² - 3 since the vertex is at (2, -3).

We have,

From the graph given,

The vertex is at (2, -3).

Now,

The vertex form of a quadratic function is given by:

f(x) = a(x - h)² + k

Where (h, k) is the vertex of the parabola.

Given the vertex (2, -3), we can plug in the values of h and k into the vertex form:

f(x) = a(x - 2)² - 3

Thus,

The equation of the function graphed below is f(x) = a(x - 2)² - 3

A speaker is in the shape of a cube with an edge length of 3.5 inches. The speaker is sold in a package in the shape of a square prism with a base area of 16 in2 and a height of 4.25 inches. What is the surface area of the package

Answers

Step-by-step explanation:

A square prism is a three-dimensional cuboid where the base and top are equal squares and the remaining 4 faces are rectangles.

to get the surface area of the package (that square prism) the size of the content inside is irrelevant and only there to confuse us.

the package has a base area of 16 in².

that means it also has a top (or cover) area of the same size : 16 in².

as top and bottom are squares, that means their areas are the square of their side lengths.

therefore, the side length of such a square is

s = sqrt(16) = 4 in

now we know also the dimensions of the 4 rectangles that are the side areas (faces) : 4 in × 4.25 in

the area of such a rectangle is

4 × 4.25 = 17 in²

so, the total surface area is (top and bottom + 4 side areas)

2×16 + 4×17 = 32 + 68 = 100 in²

Plz help! Plzzzzz Solve systems of Equations by substitution
y= 5x - 7
-3x - 2y = -12
Slove step by step​

Answers

Answer:

(2,3)

Step-by-step explanation:

- Substitute the equation for y instead of the y variable.

-3x - 2(5x - 7) = -12

-3x - 10x + 14 = -12

-13x = -26

x = 2

- Now substitute the value of x into the other equation.

y = 5x - 7

y = 5(2) - 7

y = 10 - 7

y = 3

Answer:

x = 2 and y = 3

Step-by-step explanation:

y = 5x - 7

-3x - 2y = -12

Substitute y into the second equation:

-3x - 2(5x-7) = -12

Simplify:

-13x = -26

x = 2

Substitute x into the first equation:

y = 5(2) - 7

y = 10 - 7

y = 3
