Short Answerx1 = 4.8284
x2 = - 0.828
RemarkSubstitute the value for y from the first equation into the second equation. Multiply by 4 and then see if it factors out. Solve for x first and then y.
Step one Solve for y in the first equation. Subtract x from both sides.
y = 2 - x
Step TwoEquate the two ys.
2 - x = - 1/4x^2 + 3
Step ThreeBring the left side over to the right side.
0 = -1/4 x^2 + x + 3 - 2 Combine the like terms.
0 = -1/4 x^2 + x + 1
Step Four0 = -1/4 x^2 + x + 1 Multiply through by 4
0 = - x^2 + 4x + 4
Step fiveThis won't factor. The only thing you can do is use the quadratic equation for roots.
a = - 1
b = 4
c = 4
x = 2 +/- sqrt(4^2 * 2) / (- 2)
x = 2 +/- 4 sqrt(2) / - 2
x = 2 -/+ 2 sqrt(2)
x = 2 -/+ 2 *(1.414)
x = 2 -/+ 2.828
x1 = 4.8284
x2 = - 0.828
Graphing it @ https://www.desmos.com/calculator , we get that f(x) clearly approaches inf at x=10 and a vertical asymptote is clearly 10
Answer:
negative square root 21 over 5
Step-by-step explanation:
The previous answer was only wrong because their answer was different from their explanation. They forgot the negative sign in front. simple slip up. Give them the rating instead. The attached images are proof.
Answer:
135000
Step-by-step explanation:
first i took 200% of 54000 (54000 . 2) which is 108000
then found out the 50% which is 27000
then i added them and got 135000 :)
