It's the Identity property of Multiplication because:
a x 1 = a
X - 2y = 3
<span>4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(</span>3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2<span> - 15y - </span><span>10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- </span>√(33^2 - 4*6*33)<span>)/12
</span>y = (-33 +- √(297)<span>)/12
</span>so there are 2 solutions for y:
y1 = (-33 + √(297)<span>)/12
</span>y2 = (-33 - √(297)<span>)/12
</span>pick one and then substitute the y value in the first equation to find x
R = 9
lmk if you need the work
good luck ^^
Answer:
Step-by-step explanation:
hope it helps! im not completely sure but its the best answer!
So the first thing you have to do is look at the input and output values and find the pattern. This is probably the hardest part. So 32-12=20 and 14-12=2 so we found the pattern all you have to do is find whats missing. So we have a blank and then a 14, all you do is add 12 to the 14 to find the input so the input for that would be 26 and now to find the other missing term you subtract 12 and that gives you -22. I hoped that helped.
