Answer:

As you can see, these are all set up in slope intercept form (with a y-intercept of 0). These equations are called "direct variation" because y varies directly with x. If x increases, then y increases as well. If x decreases, then y decreases.

on a lake, Carol rowed a boat for 1/8 mile. Then luke rowed the boat for 3/8 mile. how far did carol and like row in all? simpli

Semmy [17]

Answer:

$Total = \frac{1}{2}$

Step-by-step explanation:

Given

$Carol = \frac{1}{8}$

$Luke = \frac{3}{8}$

Required

How far did they row together

To do this, we simply add the distance they both covered.

$Total = Carol + Luke$

This gives;

$Total = \frac{1}{8} + \frac{3}{8}$

Take LCM

$Total = \frac{1+3}{8}$

$Total = \frac{4}{8}$

Simplify

$Total = \frac{1}{2}$

Hence, they both rowed 1/2 mile

Together Ron and Tori have 35 trading cards. Ron has 9 more than Tori. How many cards does Ron have?

Anit [1.1K]

Ron has 22 cards
number one tip in math, try to create equation!
set number of cards Ron has as x (always set x as what you are looking for)
set number of cards Tori has as (x-9) because if Ron has 9 more cards than Tori that's same thing as saying Tori has 9 cards less than Ron
Number of cards Tori and Ron has need to equal 35
Therefore,
x + (x-9) = 35
Solve:
2x-9=35
bring over 9 to other side
2x=44
divide both sides by 2
x=22
So number of cards Ron has is 22

Y=3/4 x-4

pochemuha

Answer:

see graph of y=3/4 x-4

Step-by-step explanation:

Assuming you mean

$y = \frac34x - 4$

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.

You have to be careful on how you write these equations down. It might very well be that you meant:

$y = \frac{3}{4x-4}$ or $y = \frac{3}{4x} - 4$

However, those are more complex so I'm hoping for the first one... ;-)
