Answer: 3 to the 4 power
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
The answer is B
Because if you use your calculation right you would end up with 16,463
Answer:
Equation will be y = 5x + c
Step-by-step explanation:
For point (5, 1)
1 = 5(5) + c
Or, c = - 24
So, y = 5x - 24
D is the answer because -32 is being divided into 2 groups, each group would have 16 negatives.
