Answer:
x =- 3 and y = -7
Step-by-step explanation:
2X-2Y=-8
X=2y + 11
We need to isolate both X and Y in both equations
so
2x-2y=-8
(add 2y to both sides)
2x=-8+ 2y
(divide both sides by 2)
x=-4+y and x=2y+11
because <u>both of these equations are the same </u>we can put them together
4+y=2y+11
(subtract y)
4=y+11
(subtract 11)
-7=y
so y = -7
then to find x you just need to plug in y to one of the equations
x=2(-7) + 11
x= -14 +11
x = -3
Dylan's water bottle has a greater capacity. There are 1,000 Milliliters in a Liter. So Dylan's water bottle holds 400ml more.
The factors of this polynomial would be (x + 4)(x + 2)(x - 1).
To find these, you first have to start with long division to find the first factor. If you use x + 4 it would look like this.
= 
Now we are left with only . We can factor this by looking for numbers that multiply to the last number and add to the middle number. 2 and -2 multiply to -2 and add to 1. Therefore, we'll use those in parenthesis in their place.
(x + 4)(x + 2)(x - 1)
Answer:
$3.293
Step-by-step explanation:
You would multiply your total amount, 21.95, by your tip divided by 100, so 0.15. It would look like this: 21.95 x 0.15 = 3.293. Therefore, you would give the waitress a $3.293 tip. I Hope This Helps :)
