Answer:
x= -4
Step-by-step explanation:
An equvilent equation
remember you can do anything to an equation as long asyou do it to both sides
assuming yo have
x+y=1 and
x-3y=9
mulitply both by 2
2x+2y=2
2x-6y=18
those are equvilent
ok, solve initial
x+y=1
x-3y=9
multiply first equation by -1 and add to 2nd equation
-x-y=-1
<u>x-3y=9 +</u>
0x-4y=8
-4y=8
divide both sides by -4
y=-2
sub back
x+y=1
x-2=1
add 2
x=3
x=3
y=-2
(3,-2)
if we test it in other one
2x+2y=2
2(3)+2(-2)=2
6-4=2
2=2
yep
2x-6y=18
2(3)-6(-2)=18
6+12=18
18=18
yep
solution is (3,-2)
Yes they do form a proportion since they both simplify to 6/11
Answer: 4,988 porque 16% de 4,300 es 688 asi que nomas lo aggregas a lo que costaba y agaras el resultado de 4,988
Step-by-step explanation:
We can solve this question in the following way. Looking at the graph, we see that F(x) is shifted from one unit to the right, and it is represented by | x - 1|. Then, we can multiply this result by 4 to have the final graph, since the graph is not inverted.
Therefore, the answer to this question is F(x) = 4 * | x - 1 |.
