The equation is already in standard form since standard form is
ax^2+bx+c = 0
Here we have
a = -3
b = 4
c = -2
solve -x/3 > 5
a) x -15
c) x 15
Answer:
x must be a negative to cancel out the negative sign and must be greater than 15 unless it is supposed to equal 5 then a is correct
Step-by-step explanation:
Because 15/3 is equal to 5

The county fair charges $3.25 per ticket for the rides. Henry bought 8 tickets for the rides and spent a total of $39.50 at the fair. Henry spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use x to represent the number of ride tickets and y to represent the total cost.
(a) Find the cost of admission to the fair. Explain how you found the cost of admission.
(b) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.
(c) Explain what the coefficient on x and the constant of your linear equation represent.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Cost per ticket = $3.25
Number of ride tickets purchased (x) = 8
Total amount spent at the fair (y) = $39.50
Henry's spending was only on ticket rides and fair admission
a) Find the cost of admission to the fair. Explain how you found the cost of admission.
Total spending = amount spent on ticket rides + cost of admission to fair
$39.50 = 8(3.25) + cost of admission
39.50 = 26 + cost of admission
Cost of admission = (39.50 - 26) = $13.50
(b) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.
Since cost of admission is the same for everyone :
Total cost = 3.25x + 13.50
y = 3.25x + 13.50
(c) Explain what the coefficient on x and the constant of your linear equation represent.
3.25 = cost per ride ticket
13.50 = cost of admission to fair

In isosceles triangle DAC, AD is congruent to AC. Kiran knows that the base angles of an isosceles triangle are congruent. What additional
information does Kiran need to know in order to show that AB is a perpendicular bisector of segment CD?
A perpendicular bisector is a line that crosses (bisects) another line segment at 90 degrees, dividing the line segment it crosses into two equal length lines
The additional information Kiran need to know to show that AB is a perpendicular bisector is the fourth option;
DB and BC are congruent
The reason for the above selection is as follows:
The information about the isosceles triangle DAC Kiran knows are;
Triangle DAC = An isosceles triangle
Segment AD is congruent to segment AC
Segment AB is a is a line from the vertex point A to the side CD of triangle DAC
The required parameter:
The information Kiran has know so as to show that AB is a perpendicular bisector of CD
Method:
Determine an attribute present in triangle DAC with line AB drawn that is due to line AB being a perpendicular bisector
Solution:
For AB to be a perpendicular bisector, then DB and BC are congruent
Given that DB and BC are congruent, we get;
AB is congruent to AB by reflexive property
Therefore, given that AD is congruent to AC, we have;
Sides AD, AB, and DB in triangle ΔADB are congruent to the corresponding sides AC, BC, and AB in triangle ΔACB, which gives
ΔADB is congruent to ΔACB by Side-Side-Side, SSS, congruency rule
Therefore, ∠ABD ≅ ∠ABC, by Congruent Parts of Congruent Triangles are Congruent, CPCTC
∠ABD = ∠ABC by definition of congruency
∠ABD and ∠ABC are linear pair angles, therefore;
∠ABD + ∠ABC = 180°
∠ABD + ∠ABD = 2 × ∠ABD = 180° by substitution property
∠ABD = 180°/2 = 90°
∠ABD = 90° = ∠ABC, therefore, AB is perpendicular to CD and AB is a perpendicular bisector of CD
Therefore, the correct option Kiran need to know in order to show that AB is a perpendicular bisector of segment CD is the option; DB and BC are congruent

The perimeter of a rectangle is 42 centimeters. The length of the rectangle can be represented by (x+4) and its width can be represented by (2x - 7). What equation would you use to solve for x? *
Answer:
2(x+4) + 2(2x-7) = 42 ( If this is wrong simplify this)
Step-by-step explanation:
The formula for perimeter is (2 x length) + (2 x width), so our equation would be 2(x+4) + 2(2x-7) = 42

The Leaning Tower of Pisa in Italy was built between 1173 and 1350. A. Write an equation in slope-intercept form for the yellow line. Equation: y= b. The tower is 56 meters tall. How far off center is the top of the tower? The top of the tower is meters off center
Answer:
The answer is below
Step-by-step explanation:
From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).
a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through
[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Hence since it passes through (7.75, 0) and (10.75, 42), the equation is:
[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]
b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:
y = 14x - 108.5
56 = 14x - 108.5
56 + 108.5 = 14x
164.5=14x
x = 164.5/14
x = 11.75
When the tower is 56 meters tall, the top of the tower is 11.75 m off center

This is equivalent to 2*sqrt(34)
=======================================================
Explanation:
First let's find BD
The three triangles are similar, allowing for the proportion to be set up
AD/BD = BD/DC
9/x = x/8
9*8 = x*x
x^2 = 72
x = sqrt(72)
BD = sqrt(72)
Now we can use the pythagorean theorem. Focus on triangle BDC.
The legs are BD = sqrt(72) and DC = 8. Let's find the hypotenuse
(BD)^2 + (DC)^2 = (BC)^2
(sqrt(72))^2 + (8)^2 = m^2
72 + 64 = m^2
136 = m^2
m^2 = 136
m = sqrt(136)
We can simplify this but your teacher has chosen not to. If you want to simplify, then,
m = sqrt(136)
m = sqrt(4*34)
m = sqrt(4)*sqrt(34)
m = 2*sqrt(34)

I know the answer, I need to know how to solve
Answer:
k = 9
Step-by-step explanation:
For this, we can factor the top expression to look like the bottom expression.
So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.
18[tex]x^{2}[/tex] 11x
1 and 18 19 - No
2 and 9 11 - Yes
3 and 6 9 - No
So, the numbers are 2 and 9. The expression should now look like this:
[tex]x^{2}[/tex] + 2x + 9x + 18
Now, undistribute the terms.
x(x + 2) + 9(x + 2)
(x+2)(x+9)
This matches up with the bottom expression.
The value of k is 9.

I believe A isn't parallel because it's supposed to have the same number but they're one off from each other
