Explanation:
You are probably familiar with the formula [tex]a^2+b^2 = c^2[/tex] which is the pythagorean theorem.
The [tex]a^2[/tex] is the square of the first leg 'a', while [tex]b^2[/tex] is the square of the second leg b. Adding those two squares leads to the square of the hypotenuse c, aka [tex]c^2[/tex]. This only works with right triangles, which are triangles that have a 90 degree angle.

Yeah bit confused need help
Answer:
[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]
Step-by-step explanation:
Basically, x is 2 times smaller than y, or
y is 2 times larger than x.
For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8
Another example:
When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6
I don't know which one you're looking for, but try putting in
x = 1/2y or y = 2x

divide 0.63512 by 13.6
Answer:
21.413
Step-by-step explanation:
Change the divisor 0.63512 to a whole number by moving the decimal point 5 places to the right. Then move the decimal point in the dividend the same, 5 places to the right.
We then have the equations:
1360000 ÷ 63512 = 21.413
and therefore:
13.6 ÷ 0.63512 = 21.413
Both calculated to 3 decimal places.
The table shows the cost of movie tickets based on the number of tickets purchased. PLEASE HELP ME
Number of Tickets Cost
2 $17.00
3 $25.50
4 $34.00
5 $42.50
Based on this proportional relationship, find the constant of proportionality (r). Using the value for r, enter an equation that will calculate the cost (y) of x movie tickets in the form of y=rx. The answer is not y=8.5 Please help the one who gives me the correct answer will get brainliest
The proportional relationship is given by y = 8.5x
Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.
Let x represent the movie tickets and y represent the cost.
Since x and y are proportional, hence:
y ∝ x
y = rx
Where r is the constant of proportionality.
From the table to find x, when y = 17, x = 2, hence:
17 = 2r
r = 8,5
y = 8.5x
The proportional relationship is given by y = 8.5x

Original line: y = -5/6x - 1
A line that is parallel to the original will have the same slope. To find the new y-intercept, we'll take the original line, plug in the given point, and solve for b.
y = -5/6x + b
-2 = -5/6(5) + b
-2 = -25/6 + b
b = 13/6
Parallel Line: y = -5/6x + 13/6
A line that is perpendicular to the original will have the opposite reciprocal slope. To find the new y-intercept, we'll take our perpendicular slope, plug in the given point, and solve for b.
y = 6/5x + b
-2 = 6/5(5) + b
-2 = 6 + b
b = -8
Perpendicular Line: y = 6/5x - 8
