1. How do you define quadratic equations?
Answer:
[tex]ax^{2} +bx+c^{2}=0[/tex]
Step-by-step explanation:
A quadratic equation is a equation that takes the form: [tex]ax^{2} +bx+c^{2} = 0[/tex]
Ex. Using our definition of quadratic equations, [tex]ax^{2} +bx+c^{2}=0[/tex],
We can set a = 2, b = 1, c = 6:
[tex]2x^{2} +x+6^{2}=0[/tex]
[tex]2x^{2} +x+36=0[/tex]
Which can then be solved (if you are trying to solve it) as:
[tex](2x+9)(x-8)=0[/tex]
[tex]x=\frac{9}{2}, 8[/tex]

You recently borrowed $500 from a friend. You signed a contract that requires you to pay back one third of the loan every month for three months. How much will you have to pay back each of the first two months? How much will you have to pay back the third month?
The amount of money I would repay in the first month is $166.67.
The amount of money I would repay in the second month is $166.67.
The amount of money I would repay in the third month is $166.66.
How much would I repay each month?In order to determine the money that would be repaid each of the first two months, multiply 1/3 by the amount of the loan.
1/3 x $500 = $166.67
Amount to be repaid in the third month = $500 - (166.67 x 2) = $166.66

Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h

Answer:
-13.7 is the answer!Graph a parabola whose vertex is at (3,5)(3,5)left parenthesis, 3, comma, 5, right parenthesis with yyy-intercept at y=1y=1y, equals, 1.
Using the given information we found that the equation of the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.
How to get the equation of the parabola?
For a parabola with vertex (h, k), the equation is:
y = a*(x - h)^2 + k
Here the vertex is (3, 5), so the equation is:
y = a*(x - 3)^2 + 5
And the y-intercept is y = 1, this means that:
1 = a*(0 - 3)^2 + 5
1 = a*9 + 5
1 - 5 = a*9
-4/9 = a
So the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.

Answer:
Slope = 1.000/2.000 = 0.500
x-intercept = 20/-1 = -20.00000
y-intercept = 20/2 = 10
Step-by-Step Explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-1/2*x+y-(10)=0 <----- given linear equation
STEP 1:
Simplify 1/2
Equation at the end of step 1:
((0 - (1/2 • x)) + y) - 10 = 0
STEP 2 : Rewriting the whole as an Equivalent Fraction
Adding a whole to a fraction
Rewrite the whole as a fraction using 2 as the denominator :
y = y/1 = y · 2/2
Equivalent fraction :
The fraction thus generated looks different but has the same value as the wholeCommon denominator :
The equivalent fraction and the other fraction involved in the calculation share the same denominatorAdding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-x+y• 2 /2 = 2y-x/2
Equation at the end of step 2:
(2y-x)/2-10=0
Step 3:
Rewriting the whole as an Equivalent Fraction :
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
10=10/1=10 * 2/2
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
(2y-x)-(10*2)/2=-x+2y-20/2
Step 4:
Pulling out like terms :
Pull out like factors :
-x + 2y - 20 = -1 • (x - 2y + 20)
Equation at the end of step 4:
-x+2y-20/2=0
Step 5: When a fraction equals zero :
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-x+2y=20/2 *2=0*2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-x+2y-20 = 0
Equation of a Straight Line
Solve -x+2y-20 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line -x+2y-20 = 0 and calculate its properties
Graph of a Straight Line : PICTURE
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000
y-intercept = 20/2 = 10
Calculate the X-Intercept :
When y = 0 the value of x is 20/-1 Our line therefore "cuts" the x axis at x=-20.00000
x-intercept = 20/-1 = -20.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is 11.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 11.000 - 10.000 = 1.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.000/2.000 = 0.500
Geometric figure: Straight Line
Slope = 1.000/2.000 = 0.500
x-intercept = 20/-1 = -20.00000
y-intercept = 20/2 = 10

Find the midpoint of the segment with the following endpoints.
(8,4) and (2,7)
Answer: The midpoint is (5,5.5)
Step-by-step explanation:
Adding X1 And X2 equals 10. Then the x variables have to be divided which is 10 divided 2 equals 5, the 5 represents the x value of the x part of midpoint. (5,?)
Adding Y1 and Y2 equals 11. Then the y variables have to be divided by 2 which is 11 divided by 2 equals 5.5, the 5.5 represents the y value of the midpoint. (?,5.5)
The final answer is Midpoint = (5,5.5)

The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part B: Justify why the relationship shown in the graph is a proportional relationship.
Answer:
Step-by-step explanation:
Let the equation of the line representing relation between the euros and dollars is,
E = mD + b
Where 'E' = Number of euros
D = Number of dollars
m = slope of the line
b = y-intercept
Slope of a line which passes through two points (120, 90) and (400, 300) will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{300-90}{400-120}[/tex]
m = 0.75
Equation of the line passing through (120, 90),
90 = 0.75(120) + b
b = 90 - 90 = 0
Therefore, equation of the line will be,
E = mD
E ∝ D
Here m = Proportionality constant
And the relation between the numbers of Euros and US dollars is a proportional relationship.
If b + 2a = c and 2a +b = 10, then what is c
