What is the graph of the function x^2-9x+20 over x-4

Greeley [361]

Answer:

a straight line: y = x -5, with a hole at (4, -1)

Step-by-step explanation:

The rational function can be simplified to ...

$f(x)=\dfrac{x^2-9x+20}{x-4}=\dfrac{(x-5)(x-4)}{(x-4)}\\\\f(x)=x-5\qquad\text{$x\ne 4$}$

The graph of this is a straight line, with a hole at x=4, where the function is not defined.

Help,anyone can help me do quetion,I will mark brainlest.

maks197457 [2]

180m

To find this we need to find the perimeter. The perimeter is not given so we need to find it. If the land is square we can assume all sides are the same length. So to find the perimeter we need to find the side length. So we find the square root of the volume. The square root of 2025 is 45. So we now add all the side lengths together. The equation is 45+45+45+45. This makes 180m. It takes 180m of fence.

Hope this helps. Please consider making me the Brainliest, it’s not necessary but it is appreciated as I put time and research into each answer. Have a great day, stay safe and stay healthy.

Determine the unit rates represented by<br> 1. Zephra ran 2 miles in 0.25 hour.

Harlamova29_29 [7]

The unit rate represents 2 miles in 0.25 hour is 8 miles per hour

Step-by-step explanation:

Let us revise the meaning of rate and unit rate

1. A rate is a ratio that is used to compare different types of quantities

2. A unit rate shows how many units of the first type of quantity

corresponds to one unit of the second type of quantity

Examples:

Cost per item

Distance per hour

∵ Zephra ran 2 miles in 0.25 hour

- To find the unit rate make the denominator of the ratio = 1

∵ The unit rate = $\frac{2}{0.25}$

- Divide up and down by 0.25

∵ 2 ÷ 0.25 = 8

∵ 0.25 ÷ 0.25 = 1

∴ The unit rate = $\frac{8}{1}$

∴ The unit rate = 8 miles per hour

The unit rate represents 2 miles in 0.25 hour is 8 miles per hour

The sum of 14 and a number is equal to 7

NikAS [45]

The sum (+) of 14 and a number (x) is equal to (=) 7.

14 + x = 7

To solve, subtract 14 from both sides.

x = -7
