Answer:
1/2
Step-by-step explanation:
1/4 (4x - 8) + 3x =0
distribute the 1/4
x-2+3x=0
combine like terms
-2+4x=0
move -2 to the other side [by ADDing +2 to each side
4x=2
divide [by 4 on both sides]
x=1/2
I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y
Answer:(1-w) (1-w*2)
=1-w*2-w+w*3
=1-w-w*2+1
=1-1+1
=1
Step-by-step explanation:
at first we should multiply them with each other
then, put the value of w*3 i.e. w*3=1
then, put the value of -w-w*2 i.e. 1
then, the final answer is 1.
Answer:
c
Step-by-step explanation:
because it is increasing exponentially
Answer: (2,2), (4,2)
First, I subtracted 2y from both sides of the second equation. Then, I substituted -2y+6 in for x in the first equation (-2y+6)²+4y²=20. Then, I expanded 4y²-24y+16+4y²=20. Next, I combined like terms, and moved everything to one side 8y²-24y+16=0. Then, I factored out an 8, and then finished factoring 8(y-2)(y-1). This gives me my y-values, y=1,2. Next, I inserted each y-value into the second equation and got x=-2(1)+6 ---> x=4 (The first solution is (4,1). ) and x=-2(2)+6----->x=2 (The second solution is (2,2).
