Twice the sum of 'x' and 'y' . . . 2(x+y)
The sum of twice 'x' and 'y' . . . (2x+y)
2(x+y)=2x+2y
(2)x=Y-4
what is 10 squared DOES NOT equal what?
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
3(2y)(x)6xy
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
2(x+y)=2x+2y
2(2+Y)
The difference between a number x and twice y is equal to fifteen.
y=2x
(2)x=Y-4
2.(2+y) = 2.2 + 2.y = 4 + 2y
Twice-differentiable simply means that the function can be differentiated twice. eg. If y = x^5 (^5 means to the power of 5). Then y' = 5x^4 (i.e. differentiating once) Then y'' = 20x^3 (differentiating twice)

2(xy)
y intercept is value of y when x = 0 x intercept is value of x when y = 0 if y intercept is twice x intercept then its value is twice as high Mathematically, the standard form equation is y = mx + b where m = slope and b = y intercept for x intercept let y = 0 0 = mx + b x = -b/m = 1/2 y intercept = 1/2 time b m = -2 y = -2x + b is the equation
