Which of the following equations is quadratic?
A) (x+3)(x+4)= 5
B) 5(4x+2) = 3
C) x(x^2+ 1) = 0
X+8=-2
O A. x= 10
OB. x=-6
O C. x=6
OD. x= -10
D is the correct answer
X+8 = -2
x = -8 -2 = -10
Answer: option D
Step-by-step explanation:
X+8=-2
x= -2-8 (you should make x the subject so you switch the +8 to the other
x= -10 side which becomes -8)
so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D
At a school dance, tickets are sold at the door and each ticket is the same price. the amount of money the school makes from the dance is equal to the total amount of money collected from ticket sales minus the total cost of the dj and decorations. for this dance, the total cost is fixed and is not dependent on the number of tickets sold. if 75 tickets are sold, the school loses $150. if 100 tickets are sold, the school makes $100. what is the total cost of the dj and decorations?
Answer:
$900
Step-by-step explanation:
x = the cost of the tickets
y = the cost of dj & decorations
In the first situation, the profit of -$150 = 75x - y
In the second situation, the profit of $100 = 100x - y
Using the first situation, we isolate y as follows:
-150 = 75x - y
Add y to each side: y-150 = 75x
Add 150 to each side to isolate y
y = 75x + 150
Use this formula in the second situation in place of the y
Original formula: 100 = 100x - y
With substitution: 100 = 100x - (75x + 150)
Simplify to: 100 = 25x - 150
Add 150 to both sides: 250 = 25x
Divide both sides by 25: 10 = x
Input the 10 in for x in either formula above
-150 = 75(10) - y
-150 = 750 - y
Add y to both sides
y - 150 = 750
Add 150 to both sides
y = 900

Fiona recorded the mean math exam grade for six random samples of students from the entire seventh-grade class. Sample Sample Mean Grade 1 65 2 92 3 78 4 45 5 95 6 70 Why is a valid prediction for the mean of the population not possible using these samples?
The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.
Why can't Fiona use the means she recorded?Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.
In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.

Does the table represent a function? Why or why not?
X Y

6 6
A. Yes, because every x-value corresponds to exactly one y-value.
B. Yes, because there are different y values.
C. No, because one x-value corresponds to two different y-values.
D. No, because the y values are positive.
The table does not represent a function because (c) No, because one x-value corresponds to two different y-values.
How to determine the true statement?The table of values is given as:
X Y
3 1

6 6
From the table of values, we have:
Y = 5 and 6 when X = 6
A table of values that is a function would have a y value of each x value
Hence, the table does not represent a function because one x-value corresponds to two different y-values.

find the value of a 3a+2b=8 and b=-2
Answer:
The value of a in the given equation is '4'
Step-by-step explanation:
The given equation is: 3a + 2b = 8 and b = -2
Plug the value of b into the formula:
3a + 2(-2) = 8
3a - 4 = 8
We want 3a by itself so we will add +4 to both sides:
3a - 4 + (4) = 8 + (4)
3a = 12
Divide both sides by 3 so a is by itself:
3a/3 = 12/3
1a = 4
a = 4

1. There are 46 students in the orchestra and twice that number in the band. There are 34
boys and 23 girls in the choir. If each student only participates in one group, how many
students total are there in the orchestra, the band, and the choir?
The total number of students in the orchestra, the band, and the choir is 195
Determining the number of students
From the questions, we are to determine how many students in total are in the orchestra, the band, and the choir
From the given information,
There are 46 students in the orchestra and twice that number in the band.
Thus,
Number of students in the orchestra = 46
Number of students in the band = 2 × 46 = 92
And
There are 34 boys and 23 girls in the choir
∴ Number of students in the choir = 34 + 23 = 57
Then,
The total number of students in the orchestra, the band, and the choir = 46 + 92 + 57
Total number of students in the orchestra, the band, and the choir = 195
Hence, the total number of students in the orchestra, the band, and the choir is 195

Toby has $70 saved.He is saving $15 more each week.In how many weeks will he have $280 saved to buy the new skateboard he wants?
Answer:
14 weeks
Step-by-step explanation:
Let's create and equation to display this situation. Toby already has $70 saved, so that is not the variable and no x should go next to it. He is saving $15 more each week. Lastly, we want to end up with $280 saved. The equation will look like this, given the information:
15x + 70 = 280
To find how many weeks it will take, solve the equation!
15x = 210 Subtract 70 from 280
x = 14 Divide 210 by 15
Therefore, it will take Toby 14 weeks to save up for a new skateboard.
