The sum of two numbers is 1. The difference of the numbers is 9. What are 5 points
Svetradugi [14.3K]

Answer:

The numbers are 5 and -4

Step-by-step explanation:

let the numbers be =x and y

x+y=1—eqn 1

x-y=9—eqn 2

Add both equations

2x=10

x=5

Plug x=5 into eqn 2

5-y=9

5-9=y

y=-4

A piece of rectangular sheet metal is 20 inches wide. Its is to be made into a rain gutter by turning up the edges to form paral
vivado [14]
Turning up the edges of the sheet metal will result in the 20 inches of metal being divided into x inches of the first side, then the unknown width of the gutter (let's call it "y") and then again x inches for the second side.

 As a picture: x|______|x/y

 As a formula: 20 = x + y + x = 2x + y

Resolving this to y we get: 20 - 2x = y

and switching it around: y = 20 - 2x,

Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).

A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be: A(x) = 20x - 2x^2

The function f(x) = x2 + 10x - 3 written in vertex form is f(x) = (x + 5)2 – 28. What are the coordinates of the vertex?
alina1380 [7]

Answer:

<h2>(-5, -28)</h2>

Step-by-step explanation:

The vertex form of a quadratic function <em>f(x) = ax² + bx + c</em>:

f(x) = a(x - h)² + k

(h, k) - coordinates of a vertex

We have <em>f(x) = x² + 10x - 3</em> in the vertex form <em>f(x) = (x + 5)² - 28</em>.

f(x) = (x - (-5))² + (-28) → h = -5, k = -28
