Answer:

(1/2, -3)

Step-by-step explanation:

We have the following equations:

y = 4 * x - 5

y = –3

To solve algebraically, we must replace one equation in another, and we are left with:

-3 = 4 * x - 5

4 * x = 5 - 3

x = 2/4

x = 1/2

Therefore the solution is (1/2, -3)

Now, when we graph both equations, the solution would be the intercept between both graphs, attached corresponding image, the solution would be the same (1/2, -3)

Let the length of the patio is x and width is 3/4x
So according to the equation x.3/4x = 432
x^2. 3/4 =432
x^2 =432 times 4/3
x^2 =1728/3 =576
x= 24

In a 30-60-90 triangle, the hypotenuse is the shorter leg times the square root of two.
olga55 [171]
The correct answer is C "never."

The hypotenuse in a 30-60-90 triangle is the shorter leg doubled. So, it's 2x where x is the shorter leg.

In fact, the square root of two is not used to calculate any other sides in a 30-60-90 triangle. The shorter leg is x, the medium leg is x√3, and the hypotenuse is 2x.
