The answer is f(x) = 5 - 2x
Function form means just replace y with f(x).
So given 8x + 4y = 20:
Subtract 8x
4y = 20 - 8x
Divide both sides by 4
y = 5 - 2x
Answer:
28
Step-by-step explanation:
2x + 3x + 40 =180
5x= 180 - 140
5x=140
x= 28
Answer:
√30-√18+√55-√33/2
Step-by-step explanation:
What is the following quotient? sqrt6+sqrt11/sqrt5+sqrt3
Given the expression
√6+√11/√5+√3
Rationalize
√6+√11/√5+√3 × √5-√3/√5-√3
= √30-√18+√55-√33/√25-√9
= √30-√18+√55-√33 /5-3
= √30-√18+√55-√33/2
This gives the required quotient
Positive number are on the right of the zero on the number line.
