Answer:
use the theorem of pythagoras
LM=MN²+LN²
9²=X²+6²
81=X²+36
-x²=36-81
ײ=36+81
ײ=117
x=10
Answer:
I'll be your friend, friend! :D
Step-by-step explanation:
First of all, use substitution to find slope
(1) = m(3) - 2
3 = m3
m = 1
With both the slope and y int, you can write it in y int form
y = 1x - 2
Convert that to standard form
-x + y = -2
Steps:
1. Do a proportion
2/3 times x/12
2. Do 12 times 2=24
3. Divide 24 by 3
4. Your answer is 8 girls
Or you could do it this way
Steps:
1. You could have just multiplied the 2 by a 4 to get 8.12 boys divided by 3 boys is 4. That means you multiple the two by 4 to get the girls.
Answer:
Step-by-step explanation:
By definition, a relation is a function if each input value has one and only one output value.
The input values are the x-values and the output values are the y-values.
Given:
and 
We can identify that we need to find the output values of these input values:
Observe in the graph attached that:
- When

- When
Therefore:
