Answer:
(1,4)
x= 1
y= 4
(I checked on desmos and this is correct)
Step-by-step explanation:
I'm going to solve this by substitution
To do this we need to get a variable by istelf in any equation
We'll start with 18x-2y=10
We can add 2y and divide by 2 to get
y=9x-5
This is what y will equal for now and we can plug this in for y in the second equation
3x+16(9x-5)=67
This is rather easy to solve
147x-80=67
147x=147
this means that x=1
We can then use this value for x and plug it into any equation
let's just do the first one
18*1-2y=10
This is easy to solve as well and you should get
-2y=-8
y=4
this means that x=1
y=4
If you observe the graph, the graph is touching the x-axis at the point x=-1 and is turning away.
This means, the graph as an even multiplicity at x=-1. So the two roots of the given polynomial are x = -1 and x = -1. Thus, the two factors of the polynomial are (x+1) and (x+1)
Product of the factors is equal to the polynomial. So the given polynomial will be (x+1)(x+1).
Therefore, the answer to this question is option C
Answer:
x = 2/9
Step-by-step explanation:
3x = 2/3
3*3x = 2
9x = 2
x = 2/9
Check:
3*2/9 = 2/3
6/9 = 2/3
