Answer:
The equation is y= 0,65 x
If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately pays (y) is the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.
The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).
Step-by-step explanation:
Answer:
Option A.) is correct by AA similarity. There are two angles that are congruent given by
.
This is because both pairs represent alternate interior angles formed by lines intersecting two parallel lines.
Step-by-step explanation:
From the given figure we can say that
i) Option A.) is correct by AA similarity. There are two angles that are congruent given by
.
This is because both pairs represent alternate interior angles formed by lines intersecting two parallel lines.

Answer:
x = 7
Step-by-step explanation:
The equation can be rewritten to ...
8x = 13n +4 . . . . for some integers x and n
x = (13n +4)/8
For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.
x = (13·4 +4)/8 = 56/8
x = 7

The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.
Trigonometric Functions:
You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.
Rearrange the formula to find H (PR):
