Write an equation of the line that passes through (18,2) and is parallel to the line 3y-x=-12 .

uysha [10]

Answer:

$y = \frac{1}{3}x-4$

Step-by-step explanation:

Step 1: Solve for y in the first equation

$3y - x = -12$

$3y - x + x = -12 + x$

$\frac{3y}{3} = \frac{x}{3} - \frac{12}{3}$

$y = \frac{1}{3}x - 4$

Step 2: Determine the important aspects

We know that our line is parallel to the other line that has a slope of 1/3 which means that our slope is also going to be 1/3. We also know that our line crosses the point (18, 2) which means that we can use the point slope form to determine our equation

Point Slope Form → $(y-y_1) = m(x - x_1)$

Step 3: Plug in the information and solve

$(y-2) = \frac{1}{3}(x - 18)$

$y - 2 = \frac{1}{3}x - 6$

$y - 2 + 2 = \frac{1}{3}x - 6 + 2$

$y = \frac{1}{3}x-4$

Answer: $y = \frac{1}{3}x-4$

The two triangles are similar. What is the value of x?

Tcecarenko [31]

If they are similar, their sides are proportional. The scale factor would be 20/28, which is 5/7.

5/7 = 3x/4x+2
Cross multiply
20x+10 = 21x
subtract 20x on both sides
10 = x

x = 10

Please help I don't know what to do for number 40

valina [46]

X - tickets for adults
y - for students

$6x+4.5y=1155\\
x+y=240\\\\
6x+4.5y=1155\\
-4.5x-4.5y=-1080\\
----------\\
1.5x=75\\
x=50\\\\
50+y=240\\
y=190$
