Answer:
x = 10°
Step-by-step explanation:
As we can see it is an equilateral triangle so all sides and angles are equal.
6x + 6x + 6x = 180° { being sum of angles of triangle }
18x = 180°
x = 180° / 18
x = 10°

1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
The required function is:
Option 3: 
Step-by-step explanation:
The initial value and rate is used to write exponential function
Here
Given
Initial value = 37
Rate = r = 5%
When the rate is 5%, the next year the quantity will be 1+0.05 = 1.05 time of the current quantity.
So,
The function can be written as:
For initial value, put t=0
Hence,
The required function is:

Answer:
10
Step-by-step explanation:
thats the answer
x=5
2x=10
x√3=√170
Answer:
In general, when y = f(x), you are substituting a permissible x value into function f & its calculated 'output' is the value for y. Then (x,y) is an ordered pair, i.e. coordinates of a point on the graph. ... So our ordered pair is (-14,11).
