Write and equation of a line that is parallel to the line below and passes through the given point

Answers

a line parrelel would have the same slope

in y=mx+b   m=slope and b=yintercept

so y=-2/3x-5 
the point you want is -3,11 or this equation is true when x=-3 and y=11 are true so subsitute and solve for the new 'b'

11=-2/3(-3)+b
11=2+b
subtract 2 from both sides
9=b

the equaqtion is y=-2/3x+9
If one line is parallel to another, that means the two lines have the same slope.  Therefore, since the line you are creating is parallel to the line y = -2/3x - 5, it's slope must be the same, -2/3.  Additionally, you know it passes through the point (-3, 11).

If you don't remember the slope-intercept equation, it looks like this:
y = mx + b, where m is the slope, b is the y-intercept, and x and y are, well, x and y.

Let's plug in the slope we know it must have (-2/3)  and plug in the (x, y) coordinates we were provided so that we can find b.
11 = -2/3(-3) + b

Solve for b:
11 = 2 + b
9 = b

Now we know our slope and our y-intercept, after solving for it, so we can write our final equation!

The answer is: y = -2/3x + 9

If the ratio of blue shirt to green shirts is 5:12 with a total of 340 shirts, how many shirts are blue

Answers

100.
You add 5 and 12 together. 17.
Devide 340 by 17, you get 20.
Then times it by 5(blue shirts) and you get 100.

Final answer:

To solve this, you first add the parts of the ratio (5+12), which totals 17 parts. Divide the total number of shirts (340) by the total parts (17) to get shirts per part (20). Finally, you multiply the number of parts for blue shirts (5) by the number of shirts per part (20), resulting in 100 blue shirts.

Explanation:

In order to determine how many shirts are blue, we must first understand the concept of ratios. In this case, the total ratio is given as 5:12, representing the ratio of blue shirts to green shirts respectively. This ratio means for every 5 blue shirts, there are 12 green shirts.

The total number of shirts given is 340. To find out the number of blue shirts, we first add the parts of the ratio together. 5 (for blue) + 12 (for green) equals a total of 17 parts. To find the value of a single part, we divide the total number of shirts by this number: 340 shirts ÷ 17 parts = 20 shirts per part.

Since we know there are 5 parts for the blue shirts, we simply multiply this by the number of shirts per part: 5 parts (blue) * 20 shirts per part = 100 blue shirts.

Solve each proportion.
6/19=x-12/2x-2
What’s the answer?

Answers

the solution for the given equation is x = 30.857.

What is proportionality?

the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.

Given an equation, 6/19=x-12/2x-2

Simplifying this using PEMDAS

cross multiple the equation

12x -12 = 19x -12*19

on the same side

-7x = -228 +12

-7x = -216

x = 216/7

x = 30.857

Therefore, the solution for the given equation is x = 30.857.
