Answer:
x=2
Step-by-step explanation:
1.|x-8|=3x
2. |x-8|-3x=0
3. x-8-3x=0 , -(x-8)-3x=0
4. x=-4 , x=2
5. x=all real numbers , x=2
2 crates contain 12 cases each. In each case are 12 dozen eggs. The two crates contain 24 cases each because 12+12=24. All 24 have 12 eggs each. Multiply 24 and 12 to get 288 eggs.
Answer:
x=-1, y=-5 ---> (-1, -5)
Step-by-step explanation:
so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of 4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)
If 2/3 of the cards are face-up, then 2/3*12=8 cards are face-up. The remaining 12-8=4 cards are therefore face down.
Answer:
x^2 +2x +1
Step-by-step explanation:
(x+1)^2
=(x+1)(x+1)
= x×x+x×1+1×x+1×1
=x^2+x+x+1
=x^2+2x+1
