Answer:
x = -4
Step-by-step explanation:
x+y = -10 or y = -10 - x
substitute this into the second equation
x - y = 2
x - (-10-x) = 2
2x + 10 = 2
2x = -8
x = - 4
Answer:
<h2>All three functions have a y-intercept.</h2>
Step-by-step explanation:
The table is attached, there you can observe functions f(x), g(x) and h(x).
Remember, when x = 0, it represents a y-intercept. So, we can deduct that all three functions have y-intercept, (0,1) for f(x), (0, -1/2) for g(x) and (0,-5) for h(x).
Also, x-values represent domain values, however, in this case, we can't say that all three function have the same domain values, because we don't know the domain defintion for each of them to determine such thing.
Additionally, in the table you can observe that f(x) has the greatest maxium, so the second choice is also false. And neither function has x-intercept.
Therefore, the only right answer is the third choice.
An easy way is to multiply 9 by factors of 10
10
100
1000
9 times 10=90
9 times 100=900
9 times 1000=9000
and so on
or you could find multipules of 9 that are over 27
multipulse are
9,18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,162,171,180,189,198,207,216, etc
so basically you could use any number in that list from 27 and after
You have to reduse it, so you take the top number and see how mant times it can go into the bottem number then divide the number it goes into both numbers
Answer:
the equations are coincident.
