Solve the Linear Quadratic system of equations
y=x^(2)+2x-9
y=-2x+3
9514 1404 393
Answer:
(x, y) = (-6, 15) and (2, -1)
Step-by-step explanation:
You can start by subtracting the second equation from the first.
(y) -(y) = (x^2 +2x -9) -(-2x +3)
0 = x^2 +4x -12 . . . . . . collect terms
0 = (x +6)(x -2) . . . . . . . factor
Solutions for x are -6 and +2. These values make the factors zero.
The corresponding solutions for y are ...
y = -2(-6) +3 = 15
y = -2(2) +3 = -1
Solutions to the system of equations are ...
(x, y) = (-6, 15) and (2, -1)

Sally Jones had a policy with a $250 deductible which paid 80% of her covered charges less deductible. She had medical expenses of $18,240.00. What is S
Answer
Find out the insurance company's payment .
To proof
Deductible
The deductible is the amount of money you will pay in an insurance claim before the company starts paying you insurance coverage .
As given
Sally Jones had a policy with a $250 deductible which paid 80% of her .covered charges less deductible
She had medical expenses of $18,240.00.
Amount becomes after deducting deductible = $18,240 - $250
= $17990
80 % is written in the decimal form
now 80% of the Amount after deducting deductible
= $ 14392
Therefore $ 14392 is the insurance company's payment .

49. [tex]x = \dfrac{1}{a}[/tex] and [tex]y = 3[/tex]
50. [tex]x = \dfrac{1}{2a}[/tex] and [tex]y = \dfrac{1}{b}[/tex]
Step-by-step explanation:
We are going to solve these systems of equations using the elimination method.
49. Given:
[tex]5ax + 4y = 17[/tex] (1)
[tex]\:\:ax + 7y = 22[/tex] (2)
Multiply Eqn(1) by 7 and multiply Eqn(2) by -4 to get
[tex]\:\:35ax + 28y = 119[/tex]
[tex]-4ax - 28y = -88[/tex]
Adding the two equations above, we get
[tex]31ax = 31 \Rightarrow x = \dfrac{1}{a}[/tex]
Substituting this value for a into Eqn(2), we get
[tex]y = 3[/tex]
50. Given:
[tex]4ax + \:\:by = 3[/tex] (3)
[tex]6ax + 5by = 8[/tex] (4)
Multiplying Eqn(3) by -5, we get
[tex]-20ax - 5by = -15[/tex]
[tex]\:\:\:\:\:\:6ax + 5by = \:\:8[/tex]
Adding the two equations above, we get
[tex]-14ax = -7 \Rightarrow x = \dfrac{1}{2a}[/tex]
Plugging in the value of x into Eqn(3), we get the value for y as
[tex]4a(\frac{1}{2a}) + by = 3[/tex]
or
[tex]2 + by = 3 \Rightarrow y = \dfrac{1}{b}[/tex]

Select the answer that describes the properties of a parallelogram.
Answer:
A is the correct answer because all sides are congurent
A parallelogram has two pairs of parallel sides.
opposite sides and opposite angles are congruent.
Option D is the correct answer.
We have,
Parallelograms have several notable properties:
Opposite sides are parallel:
In a parallelogram, opposite sides are parallel, meaning they never intersect and have the same slope.
Opposite sides are congruent:
The opposite sides of a parallelogram have equal lengths. This property applies to both pairs of opposite sides.
Opposite angles are congruent:
The opposite angles of a parallelogram have equal measures. This property applies to both pairs of opposite angles.
- Consecutive angles are supplementary.
- Diagonals bisect each other.
- Diagonals create congruent opposite triangles.
- Diagonals create equal opposite angles.
Thus,
A parallelogram has two pairs of parallel sides.
opposite sides and opposite angles are congruent.

QUICKLY!!!! A paper airplane was thrown from the top of a tall building.The height of the paper airplane above the ground can be found using the function `y=-1.5x+60` , where `x` is the time in seconds the airplane has been in the air.
Jayden made this table to figure out how high the plane was at different times.
0 | 60
10 | 45
20 | 30
30 | 15
40 | 0
How would the equation `y=-1.5x+60` change if the height at 0 seconds was 75?
Answer:
y = -1.5x + 75
Step-by-step explanation:
Well, the rate at which the plane falls doesn't change, so anything attached to the time variable remains constant.
In this case, the first part of the function (-1.5x) remains the same.
Since the height of the tall building was 60 and the value in the equation, we can see that the last value corresponds to the number of meters above ground.
Since the height has changed to 75, the last part of the equation (60) changes to 75, and the rest remains constant.
That gives us the following equation: y = -1.5x + 75

4. Find a value of x that is a solution to 5(x - 3) = x + 13. Describe how you found the solution
Answer:
x=7
Step-by-step explanation:
5(x - 3) = x + 13
Distribute the 5
5x-15 = x+13
Subtract x from each side
5x-15-x = x+13-x
4x-15 =13
Add 15 to each side
4x-15+15 = 13+15
4x= 28
Divide each side by 4
4x/4 = 28/4
x = 7
Answer:
x = 7
Step-by-step explanation:
First
5(x - 3) = 5x - 15 by distributing the 5 on each variable and number in the parenthesis.
Then
5x - 15 = x + 13 which you add 15 (or 5x - 15 + 15 = x + 13 +15) on both sides to have the numbers on one side because it must be the opposite to cancel out the 15 on the original/previous side.
Afterwards
5x = x + 28 now we must get the x to the other side and using the same logic as before you move the x to the other side by subtracting it (or 5x - x = x + 28 - x) to the other side equaling 4x = 28.
Finally
4x = 28 you need to divide each side by 4 to cancel out the 4 on the x since we must find out what x is (or 4x/4 = 28/4), and you should get x = 7.
