What is y=4/5x+2 written in standard form

shepuryov [24]

Answer:

$4x-5y=-10$

Step-by-step explanation:

we know that

The equation of the line in standard form is in the form

$Ax + By = C$

where

A is a positive integer, and B, and C are integers

In this problem we have

$y=\frac{4}{5}x+2$ ----> equation of the line in slope intercept form

Convert to standard form

Multiply by 5 both sides

$5y=4x+10$

$4x-5y=-10$

Which number will have the same result when rounded to the nearest ten or hundred A-97 B-118and5 C-179 D-5091

slamgirl [31]

Lets round it to the nearest ten
A 97 ====> 100
B 118 ===> 120
C 179 ===> 180
D 5091 ==> 5090
No result yet, lets round to the nearest hindred.
A 97 ====> 100
B 118 ===> 100
C 179 ===> 180
D 5091 ==> 5100
As we can see only A give the same result when we round it to the nearest hundred and nearest ten.

4. a) A ping pong ball has a 75% rebound ratio. When you drop it from a height of k feet, it bounces and bounces endlessly. If t

Klio2033 [76]

First part of question:

Find the general term that represents the situation in terms of k.

The general term for geometric series is:

$a_{n}=a_{1}r^{n-1}$

$a_{1}$ = the first term of the series

$r$ = the geometric ratio

$a_{1}$ would represent the height at which the ball is first dropped. Therefore:

$a_{1} = k$

We also know that the ball has a rebound ratio of 75%, meaning that the ball only bounces 75% of its original height every time it bounces. This appears to be our geometric ratio. Therefore:

$r=\frac{3}{4}$
