What line graph does 3x-4y=8 represent

Mathematics

1 answer:

tia_tia [17]3 years ago

6 0

Step-by-step explanation:

$4y = 3x - 8 \: \: then \: y = \frac{3}{4}x - 2$

Now you can make a table to know the graph

x =0 then y = -2
x= 4/3 then y = -1
x= 1 then y = -1.25
x=2 then y=-0.5
x=3 then y=0.25

attention : be careful the second photo is

inverted , open it and look to x-axis to know how is the graph

If 4/5 of the population of a certain town is

kkurt [141]

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600

1,600 of the people are middle class.

I hope this was helpful, keep learning! :D

Ben jogged 4 and 1/2 miles in 1 and 1/4 hours at a constant rate. How far did Ben jog in one hour? *

Mrac [35]

let's firstly convert the mixed fractions to improper fractions and then proceed.

$\stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}~\hfill \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}} \\\\[-0.35em] ~\dotfill$

$\begin{array}{ccll} miles&hours\\ \cline{1-2} \frac{9}{2}&\frac{5}{4}\\[1em] x&1 \end{array}\implies \cfrac{~~ \frac{9}{2}~~}{x}=\cfrac{~~ \frac{5}{4}~~}{1}\implies \cfrac{~~ \frac{9}{2}~~}{\frac{x}{1}}=\cfrac{5}{4}\implies \cfrac{9}{2}\cdot \cfrac{1}{x}=\cfrac{5}{4} \\\\\\ \cfrac{9}{2x}=\cfrac{5}{4}\implies 36=10x\implies \cfrac{36}{10}=x\implies \cfrac{18}{5}=x\implies 3\frac{3}{5}=x$

-|2-5| _________ (8-11) compare using < , > or =

Zolol [24]

Here is your answer

REASON:

On solving the given two terms

-|2-5|= -|-3|

= -3 (since |-3|=3)

and,

(8-11)

= -3

Hence,

-|2-5|  = (8-11)
