Plug in y=5x-1 for y in 3x+2y=11
3x+2(5x-1)=11
3x+10x-2=11
13x=13
x=1
plug x=1 to y=5x-1 to find y
y=5(1)-1
y=5-1
y=4
ANSWER: x=1 and y=4 which is (1,4) as an ordered pair

Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Variation: Inverse proportional.
This is represented as:

See attachment for table
Solving (a):
First convert variation to equation

From the table:

So, we have:





Substitute 4 for k in 


Solving (b): x when y = 25.
Substitute 25 for y in 

Cross Multiply

Divide through by 25

Take positive square roots of both sides


Angle RQU would be obtuse
Angle SQU would be acute
