Answer:
Yes, every input would have exactly one output.
Step-by-step explanation:
You don't even have to solve it, you can look at the x-values and see if there is two of the same number. If there were two of the same number that would mean it is not linear.
Hope that helps and have a great day!
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
6 / 20 and 1 / 1 <=>
6 / 20 and 20 / 20;
But, 20 / 20 > 6 / 20 => Juaquine works faster than John.
Given ΔABC with A(-6, -1), B(3, 7), and C(4, -6)
Since it is an altitude and pass thru B, t
hen it is perpendicular to AC.
so slope(AC) = (-1 +6)/(-6 - 4) = -5/10 = -1/2
perpendicular lines, slope is opposite and reciprocal so slope = 2
passes through B(3, 7)
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1
equation in slope intercept form:
y = 2x + 1
Answer:
30
Step-by-step explanation:
multiply 5 x 3 and you get 15 then multiply the roots and you also get 2 so then you have to multiply 5 and 2 to get 30.
