Given:
The values of input and outputs are given
Output is increasing by 9 for the increase in x values.

Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,




3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, 

y = 
y = 6
Answer:
First multiply the first two terms so (-0.5)(-1.2) = 0.6 as product of two negative numbers is positive number.
Step-by-step explanation:
Im BIg BrAiN :D
-3.7n - 4 = -11.9
if u want to solve it them add 4 to -11.9 which is -7.9. -7.9 / -3.7 is 2.13513514. (if you wanted to solve it)
First step, divide 6 from both sides.
t/6=r^2+1
second step, subtract 1 from both sides
t/6 -1=r^2
Now take the square root of each side.

Done!
