It depends on what the value of x is!! do you have any more info?
Answer:
Haley needs to print 65% of the tickets.
Step-by-step explanation:
Given that:
Tickets printed by Haley = 112
Tickets needed to print = 320
Tickets left to print = 320-112 = 208
Percent of tickets left to print =
Percent of tickets left to print =
Percent of tickets left to print = 0.65*100
Percent of tickets left to print = 65%
Hence,
Haley needs to print 65% of the tickets.
Answer: 50,40
Step-by-step explanation:
because a right angle is 90 degress
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
