[18].Simplify (TTE): x(2x+y+5) - 2(x²+xy+5) + y(x + y) <br>​
Dovator [93]

Answer:

x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10  + y\²

Step-by-step explanation:

Given

x(2x+y+5) - 2(x\²+xy+5) + y(x + y)

Required

Simplify

We have:

x(2x+y+5) - 2(x\²+xy+5) + y(x + y)

Open brackets

x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²+xy+5x - 2x\²-2xy-10 + xy + y\²

Collect like terms

x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 2x\²- 2x\²+xy-2xy+ xy+5x -10  + y\²

x(2x+y+5) - 2(x\²+xy+5) + y(x + y) = 5x -10  + y\²

Y intercept and slope of y= 5/2
olga2289 [7]

Answer:

y intercept at 5/2. Slope is 0

Step-by-step explanation:

The equation for a line can be represented by the formula y=mx+b. M is the slope or rate of change and b is the y intercept. Since the equation y=5/2 does not have an x in it the slope is 0 and you have a perfectly straight horizontal line. Since we are just left with 5/2 that is our y intercept.

In other words, no matter what value you plug in for x, y will always be 5/2.
