R(x)-c(x)=x²-30x+20 choose C
Answer:
Step-by-step explanation:
1) a very poor question indeed. It has at least two possible solutions
c = 3x + 2 or c = 3(x + 2)
when x = 2
c = 3(2) + 2 = 8 or c = 3(2 + 2) = 12
when x = 5
c = 3(5) + 2 = 17 or c = 3(5 + 2) = 21
2)
y = x + 2
when x = 2
y = 2 + 2 = 4
when x = 5
y = 5 + 2 = 7
Answer:
The slope-intercept form of the given equation is,

Step-by-step explanation:
The given equation of the line is,
- 4<em>x</em> + 7<em>y</em> = - 14
Adding '4<em>x</em>' on both sides of the above equation, we get
- 4<em>x</em> + 7<em>y</em> + 4<em>x</em> = - 14 + 4<em>x</em>
⇒ 7<em>y</em> = 4<em>x</em> - 14
Now, dividing both sides of the above equation by '7', we get
7<em>y</em> ÷ 7 = (4<em>x</em> - 14) ÷ 7


This is the required equation of the line in slope-intercept form.
