I hope this helps you



y=5x+6 this lines slope= -5


-3 (6x-y)= -54


6x-y= 18

y= 6x-18 this lines slope= -6


parallel lines slopes equal

-5 is not equal -6 not parallel

Answer:

lines are not parallel

Step-by-step explanation:

y = 5x + 6

–18x + 3y = –54

When the lines are parallel then the slope are equal

LEts write the equation in slope intercept form y=mx+b, where m is the slope

y= 5x+6

slope of the first line is 5

–18x + 3y = –54

Add 18x on both sides

3y= 18x-54

Divide whole equation by 3

y= 6x -18

Slope of the second line is 6

Slope of first line not equal to the slope of second line

So the lines are not parallel

Answer:

B

Step-by-step explanation:

The transformation is proved through comparing the size of the bigger triangle to the smaller triangle in the individual sides. So the size of A F/ AB should be equal to AG / AC due to transformations making A F and AG the same times longer as AC and AB. By performing those calculations, you get 3.

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
