What is the slope of a line parallel 18x+15y=90

Answer:

-6/5

Step-by-step explanation:

Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.

Answer:

\displaystyle -1\frac{1}{5}

Step-by-step explanation:

\displaystyle 18x + 15y = 90 \hookrightarrow \frac{15y}{15} = \frac{-18x + 90}{15} \\ \\ \boxed{y = -1\frac{1}{5}x + 6}

Parallel equations have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −1⅕ remains as is.

Solve for x. -1+14x 12+17
tino4ka555 [31]

Answer:

x=9

Step-by-step explanation:

These two angles are equal since they are alternate exterior angles

-1 +14x = 12x+17

Subtract 12x from each side

-1 +14x-12x = 12x-12x+17

-1+2x= 17

Add 1  to each side

-1+1+2x = 17+1

2x = 18

2x/2 = 18/2

x =9

Miles sells 3 raffle tickets for $18 and 4 tickets for $24. The pattern for the price of the tickets is the same. How much money
serg [7]

Answer:

If Miles sells 6 tickets the money he will collect be <u>$36</u>.

Step-by-step explanation:

Given:

Miles sells 3 raffle tickets for $18 and 4 tickets for $24.

The pattern for the price of the tickets is the same.

Now, to find the money miles will collect if he sells 6 tickets.

Let the money Miles will collect be x.

The ticket if sells will be 6.

As, Miles sells 3 tickets for $18.

And the pattern for the price is same.

<em>So, 3 is equivalent to 18.</em>

<em>And, 6 is equivalent to </em>x.<em />

Now, to get the money by using cross multiplication method:

\frac{3}{18} =\frac{6}{x}

<em>By cross multiplying we get"</em>

<em />3x=108<em />

<em>Dividing both sides by 3 we get:</em>

x=36.

<u><em>The money MIles will collect = $36.</em></u>

Therefore,  if Miles sells 6 tickets the money he will collect is $36.

What is the solution to this systems of liner equations y-x=6 y+x=-10
3241004551 [841]
The solution is the point where the two lines intersect (are equal) so y=y and we can say:

6-x=-10-x  upon adding x to both sides:

6=-10

This is never true so there is no solution to this system of equations.  And for this to be true the two lines must be parallel and have different y-intercepts...

A trail around a lake is 4 1/4 miles long. What is the length, in feet, of the trail?
Allisa [31]
1 mile= 5280 feet
1/5280= 4.25/x This is a proportion. 
5280 * 4.25= 22440
22440/1= 22440 

4 1/4 miles= 22440 feet

Hope this helps! :D
