C. Again, you plug 2 in for “x”. Here the answer is in fact -1, so we know that (2,-1) is a solution.
D. You just graph the two lines. As we can see, (2,-1) only falls on one of the equations. This means that (2,-1) is only a solution of “y=-2x+3”.
A total of 937 people attended the play.
Admission was $2.00 for adults and $0.75
for students. The total ticket sales
amounted to $1,109. How many students
and adults attended the school play?
First complete the equations below, where A
stands for Adults and S stands for Students.
2A + 0.75S = 1,109; A + S = 937
Now use the equations to find the number of
students and adults.
Students = [?]; Adults = []
Answers
Answer:
612 students and 325 adults
Step-by-step explanation:
I'll use substitution for this set of equations. I'll start with 2a + 0.75s = 1,109.
2a + 0.75s = 1,109
Subtract 0.75s from both sides.
2a = -0.75s + 1109
Divide both sides by 2.
a = 1/2(-3/4s + 1109)
Make 1/2(-3/4s + 1109) into a single fraction
a = -3/8s + 1109/2
Substitute -3/8s + 1109/2 for a in the other equation (a + s = 937).
-3/8s + 1109/2 + s = 937
Add -3/8s to s.
5/8s + 1109/2 = 937
Subtract 1109/2 from both sides.
5/8s = 765/2
Multiply both sides by 8/5, the reciprocal of 5/8.
s = 612
Now head back to the original equation, and substitute s for 612.
a = -3/8 * 612 + 1109/2
Multiply -3/8 by 612.
a = (-459 + 1109)/2
Add 1109 to -459 and divide by 2.
a = 650/2
a = 325
The system is solved. There are 612 students and 325 adults.

Option A is the correct answer.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To complete the square for the function.
A(x) = -2x² + 36x,
We need to first factor out the coefficient of x², which is -2:
So,
A(x) = -2(x² - 18x)
Next,
We need to add and subtract a term that will allow us to factor the expression inside the parentheses into a perfect square.
To do this,
We need to take half of the coefficient of x, which is -18/2 = -9, square it, and then add and subtract the result.
So,
A(x) = -2(x² - 18x + 81 - 81)
Now,
We can rewrite the expression inside the parentheses as a perfect square.
A(x) = -2((x - 9)² - 81)
Finally, we can distribute the -2 and simplify.
A(x) = -2(x - 9)² + 162
So,
The missing value is 162,
Thus,
The missing value is 162,

Which of the following shows the solution and graph to the inequality
2x + 1 ≤ 15?
Answers
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
Option D shows the solid dot along with [tex]x\leq 7[/tex] so our answer is
Option D.
The given inequality is 2x + 1 [tex]\leq[/tex] 15.
We have to see which of the given option shows the solution and graph to this inequality.
What are a solid dot and an open dot?A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.
We see that in the given inequality, 2x + 1 must be less than or equal to 15.
And the maximum value we can take is 7 because,
2(7) + 1
14 + 1
15
So we can take 7 and any values less than 7 i.e [tex]x\leq 7[/tex] to satisfy the inequality 2x + 1 [tex]\leq[/tex] 15.
We see that Option D gives us [tex]x\leq 7[/tex] along with the solid dot.
Hence Option D is our answer.
