Drag the tiles to the correct boxes to complete the pair.

Answer:

1. h(x) = x + 5—> f(x) = x² + 4x - 5, and g(x) = x - 1

2. h(x) = x + 3 —> f(x) = x² - 9, and g(x) = x - 3

3. h(x) = x + 4—> f(x) = x² - 16, and g(x) = x - 4

4.h(x) = x - 1—> f(x) = x² - 4x + 3, and g(x)= x - 3

Step-by-step explanation:

A) f(x) = x² - 9, and g(x) = x - 3

We are told that; h(x) = f(x)/g(x)

f(x) = x² - 9 can be factorized to;

f(x) = (x + 3)(x - 3)

Thus; h(x) = (x + 3)(x - 3)/(x - 3)

(x - 3) will cancel out to give;

h(x) = x + 3

B) f(x) = x² - 4x + 3, and g(x)= x - 3

x² - 4x + 3 can be factorized as;

(x - 1)(x - 3)

Thus; f(x) = (x - 1)(x - 3)

h(x) = (x - 1)(x - 3)/(x - 3)

h(x) = x - 1

C) f(x) = x² + 4x - 5, and g(x) = x - 1

x² + 4x - 5 can be factorized as;

(x - 1)(x + 5)

Thus; f(x) = (x - 1)(x + 5)

h(x) = (x - 1)(x + 5)/(x - 1)

h(x) = x + 5

D) f(x) = x² - 16, and g(x) = x - 4

x² - 16 can be expressed as;

(x + 4)(x - 4)

Thus; f(x) = (x + 4)(x - 4)

h(x) = (x + 4)(x - 4)/(x - 4)

h(x) = x + 4

Estimate the solution of the linear system of equations by graphing. Give approximate coordinate values to the nearest integer.

lubasha [3.4K]

The solutions to the system of equations is $(3.8,-1.6)$

Explanation:

Given the system of equations are $3y=-6x+18$ and $-35=-7x+5y$

We need to determine the solution to the system of equations.

Let us plot the equation $3y=-6x+18$ in the graph.

When $x=0$ , we get, $3y=18 \implies y=6$

When $y=0$ , we get, $-18=-6x \implies x=3$

Thus, the coordinates are (0,6) and (3,0)

Let us plot the equation $-35=-7x+5y$ in the graph.

When $x=0$ , we get, $-35=5y \implies -7=y$

When $y=0$ , we get, $-35=-7x \implies 5=x$

Thus, the coordinates are (0,-7) and (5,0)

The solution to the system of equations is the point of intersection of the two lines.

Thus, the lines intersect at the point $(3.824,-1.647)$

The approximate values of the point is $(3.8,-1.6)$

Thus, the solution is $(3.8,-1.6)$

a cylinder has a volume of 500cm³ and a diameter of 18cm. which of the following is the closest to the height of the cylinder

iragen [17]

Step-by-step explanation:

Volume of Cylinder =

$500 {cm}^{3} = \pi {r}^{2} h$

given d = 18

r = 1/2 x d = 9cm,

$\pi( {9}^{2} )h = 500 \\ 81\pi \: h = 500 \\ h = \frac{500}{81\pi} cm$

I will leave the answer in terms of Pi as I am not sure how you want to leave your answer as.
