Given that,
The given expression is : 
To find,
The value of the above expression when x = 2 and y = 4
Solution,
We have,

Put x = 2 and y = 4 in the above expression.

So, the value of the above expression is 18.
3x+2=x+6
subtract x from both sides,subtract 2 from both sides, gives you 2x=4,then divide by 2 on both sides and x will equal 2. Input the 2 for x and see if it will graph in a straight line on a graph.
Answer:
1/4
Step-by-step explanation:
The number of kids who brought their lunches is 3/7 of 84.
3/7 of 84 = 3/7 * 84 = 3/7 * 84/1 = (3 * 84)/(7 * 1) = 252/7 = 36
36 kids brought their lunches.
9 of the 36 kids got a slice of pizza.
The fraction is 9/36 = 1/4
Answer: 1/4
Step-by-step explanation:
y'=dy/dx=d/dx(4x³+3x²-2x+9)
=(3*4x^(3-1)+2*3x^(2-1)-2*1x^(1-1)+9*0
y'=12x²+6x-2
