Answer:
mulitply 2nd equation by 2
we will get
6x+6y=-10
6x-10y=-22
Subtract 2nd from 1 you will get value of y and out the value of y in 1st equation you'll get the value of x
Woman and men would be the same price, if the haircuts are very popular, each gender got the same haircut, then they also would be the same price, it is mostly about the prices, interestingness, and popularity or each barbershop, go by your nearest barbershop and see what prices they have. :))
Answer:
424 feet
Step-by-step explanation:
use the Pythagorean theorem and do 10^2+18^2=424
Answer:
see explanation
Step-by-step explanation:
Calculate the perimeters by summing the measures of the sides.
Left figure ( starting with base and summing clockwise )
x + 5 + (x - 6) + (y - 5) + 6 + y ( brackets are the measure of the indents )
= x + 5 + x - 6 + y - 5 + 6 + y
= 2x + 2y
Right figure ( starting with base and summing clockwise )
x + 2 + (x - 3) + (y - 2) + 3 + y
= x + 2 + x - 3 + y - 2 + 3 + y
= 2x + 2y
Both figures have perimeters of 2x + 2y cm
All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Given that:
Sine function
being
Cosine function
being
We will demonstrate the identity above. First of all, we need to square each equation, so:
Adding these two equations:
But as shown in the figure, using Pythagorean theorem
is always equal to 1, then:
The relation to right triangles is that:
<span>The hypotenuse is always equal to 1
</span>The opposite side is equal to
The adjacent side is equal to
