The answer is 3/5 in simplest form
Answer:
A. x = (20√3)/3, y = (40√3)/3
Step-by-step explanation:
The ratios of the side lengths of a 30°-60°-90° right triangle are (shortest to longest) ...
1 : √3 : 2
In this triangle, they are ...
x : 20 : y
Multiplying the first ratio by (20√3)/3, we get ...
x : 20 : y = (20√3)/3 : 20 : (40√3)/3
Then the values of the variables are x = (20√3)/3, y = (40√3)/3.
_____
The above side length ratios correspond to sin(60°) = cos(30°) = (√3)/2, cos(60°) = sin(30°) = 1/2. These are values you might have memorized.
This is how to distribute: 110 divide by 5= 100 divide by 5 + 10 divide by 5.
x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
Answer:
Box 1: 4
Box 2: -2
Step-by-step explanation:
A) f(1)=?
This is asking us what is at x=1??
So we look at the graph and x=1 y is at 4!
so therefore, f(1) = 4
Next...
now its asking the opposite what is f(x)=1
In other words what is x when y is 1??
So when looking at the graph, x is -2 when y is at 1!!
Therefore, f(-2) =1
