Answer:
Its C because if she found the y value she needs to find the x and she plugged in the y value for x.
About 48¢ for one pair of socks
Answer:
8 % of 4350 is a rate of $348 / yr or $29 per month.
So 124.62 - 29 = 95.62 towards the principal for the 1st month.
That would leave a balance due of 4350 - 95.62 = 4254.38.
4254.38 * .08 = 340.35.
340.35 / 12 = 28.36 interest to be paid in the second month with
124.62 - 28.36 = 96.26 going towards payment of the principal.
Step-by-step explanation:
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
