Let e=erasers and p=pencils. So we know the total amount of erasers plus pencils sold is equal to 220. Therefore,
We also know the cost of erasers and pencils totaled to $695 in earnings and so:
and so those are your two equations.
Answer:
-6xy
Step-by-step explanation:
(2x-y)x(x-2y)-(x+2y)X(2x-y)
remove the parentheses
2x^2-4xy+xy-2y^2-(2x^2-xy+4xy-2y^2)
collect terms
2x^2-4xy+xy-2y^2-(2x^2+3xy-2y^2)
remove the parentheses
2x^2-4xy+xy-2y^2-2x^2-3xy+2y^2
remove the opposites, collect the terms to get -6xy
Answer:
The 22nd Term is -77.
Step-by-step explanation:
The pattern is -5. If you subtract 5 from each starting number you'll get the following number.
Ex: 28 - 23 = 5
23 - 18 = 5
18 - 13 = 5
Subtract 5, 22 times and you will get -77.

Answer: y = -3x-3 (Choose values for x)
Step-by-step explanation:
1st change the equation to y = mx+b form
In order to change the equation to y = mx+b form subtract the 3x to both sides.
The equation now becomes y = -3x-3
2nd we can either choose values for x such has (-2,-1,0,1,2) and plug in those values into our equation y = -3x-3
For example, if we plug in x= -2 we get y= -3(-2)-3 which becomes y =3. We then plot the point (-2,3) because -2 is our x coordinate and 3 is our y coordinate.
Or we can plug the equation into a calculator that will graph the equation for you.
