Is the system of equations is consistent, consistent and coincident, or inconsistent?
y=−3x+12y=−6x+2
Select the correct answer from the drop-down menu.
Answers
Coincident is one line on the graph
Consistent is two parallel lines
Answer:
The given system of equations is inconsistent.
Step-by-step explanation:
We have been given a system of equations and we are asked to find whether our given system of equation is consistent, consistent and coincident, or inconsistent.
[tex]y=-3x+12...(1)[/tex]
[tex]y=-6x+2...(2)[/tex]
Since we know that a system of equations is inconsistent if it has no solution. Parallel lines are inconsistent because they do not intersect.
Consistent system of equations can have one or infinitely many solution. As if two lines are same then they will have infinitely many solution. If lines intersect at only one point, then they will have only one solution.
Now let us check slope of given lines.
Upon dividing equation (2) by 2 we will get,
[tex]y=-3x+1...(2)[/tex]
We can see that both lines have slope of negative 3. Since y-intercept of both equations are different, so they will not intersect at any point.
Since our given equations represent parallel lines, therefore, our given system of equations is inconsistent.

Ninas car exponentially depreciates at a rate of 7 percent per year. If nina bought the car when it was 6 years old for 12000, what was the original price of the car
Answers
hope this helps
Answer:
[tex] A(6) = 12000 = A_o e^{-0.07 *6}[/tex]
And solving for the initial amount [tex] A_o[/tex] we got:
[tex] A_o = \frac{12000}{e^{-0.07*6}}= 18263.539[/tex]
So then the original price for the car would be approximately 18263.539$
Step-by-step explanation:
For this case we can use the exponential model given by:
[tex] A(t) = A_o e^{bt}[/tex]
Where:
[tex]A_o[/tex] represent the initial amount for the car
[tex]b=-0.07[/tex] represent the exponential growth/decay rate
t represent the number of years. With t =0 at the begin
After 6 year we have that t =6, and we know this condition:
[tex] A(6) = 12000[/tex]
So then we can use the exponential model formula and the condition given and we have this:
[tex] A(6) = 12000 = A_o e^{-0.07 *6}[/tex]
And solving for the initial amount [tex] A_o[/tex] we got:
[tex] A_o = \frac{12000}{e^{-0.07*6}}= 18263.539[/tex]
So then the original price for the car would be approximately 18263.539$

b. Linear Pair
c. Definition of supplementary
d. Substitution; Combine like terms
e. Division Property of Equality
f. Definition of Right Angle
g. Definition of Perpendicular
=========================================
Further Explanations:
b. A linear pair is simply a result of cutting a straight angle into two pieces. They are adjacent and supplementary (add to 180 degrees)
c. If two angles are supplementary then they add to 180. This is simply a definition to memorize.
d. The "m < 2" is replaced with "m < 1" through the substitution property. This is possible because of statement (a) on the first line of the proof. The teacher has also combined like terms. Technically this step would require its own line.
e. Think of this as 2x = 180 solving to x = 90. The step done here is dividing both sides by 2, which uses the division property of equality. Alternatively you can use the multiplication property of equality to multiply both sides by 1/2 = 0.5
f. If an angle is 90 degrees, then by definition it is considered a right angle. This is another thing you memorize.
g. Also to be memorized is the fact that if two segments form a right angle, then they are considered perpendicular segments. The upside down T symbol means "perpendicular to"

For the figures below, assume they are made of semicircles, quarter circles and squares. For each shape, find the area and perimeter. Give your answer as a completely simplified exact value in terms of π (no approximations).
Answers
Area of the quarter circle = 1/4 πr²
= 1/4π 12²
= 36π cm²
Area of the triangle = 1/2×base×height
= 1/2 × 12×12
= 72 cm²
Thus the area of the region
= (36π-72) cm²
2. Perimeter of the first figure
The length of the arc AC is 2πr/4
= 2π×12/4
= 6π cm
the length of line AC
√(12² +12²) = 16.97
Thus the perimeter of the figure
= (6π+16.97) cm
3. The are of figure 2
Area of the semi circle πr²/2
= 12²π/2 = 72π cm²
The area of the square
= 24 × 24 =576 cm²
Area of the semi circle = 72 π cm²
Thus the area of the part of the square
= (576-72π) cm²
total area
72π +576-72π
= 576 cm²
4. Perimeter of figure 2
The length of arc AD = (2πr)/2
= 2π×12/2 = 12π cm
but length of arc AD is equal to that of arc BC
Thus arc BC = 12πcm

The original price of sn item is $25, but after the discount, you only have to pay $18.50. what is the discount (as a percent)?
Answers
The discount is 26%.
What is Discount?The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product.
Given:
Marked price = $25
Selling price = $18.50
So,
Discount = MP - SP
Discount = 25-18.50
Discount = 6.50
Now,
D% = D/MP *100
D% = 6.5 /25*100
D% = 26%
Hence, the discount percent is 26%.

Solve for x in the equation x2+20x+100=36
Answers
[tex] x = - 64 \div 22 = -2.909091[/tex]
But if x2 was supposed to be x^2 then the answer is:
[tex]x = - 4.-16[/tex]
Answer:
x = -4 and x = -16.
Step-by-step explanation:
We have the equation,
[tex]x^{2}+20x+100=36[/tex]
i.e. [tex]x^{2}+20x+64=0[/tex]
As the solution of a quadratic equation [tex]ax^{2}+bx+c=0[/tex] is given by [tex]x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}[/tex].
On comparing, a = 1, b = 20, c = 64.
So, the solution is,
[tex]x=\frac{-20\pm \sqrt{(20)^{2}-4\times 1\times 64}}{2a\times 1}[/tex].
i.e. [tex]x=\frac{-20\pm \sqrt{400-256}}{2}[/tex].
i.e. [tex]x=\frac{-20\pm \sqrt{144}}{2}[/tex].
i.e. [tex]x=\frac{-20\pm 12}{2}[/tex].
i.e. [tex]x=\frac{-20+12}{2}[/tex] and [tex]x=\frac{-20-12}{2}[/tex].
i.e. [tex]x=\frac{-8}{2}[/tex] and [tex]x=\frac{-32}{2}[/tex].
i.e. x = -4 and x = -16
Thus, the solution of the given equation is x = -4 and x = -16.

Answers
The chef has less than 25.8 pounds of rice.
She takes out 5 pounds to use during the day and stores the rest in containers.
Quantity of rice stored = 25.8 - 5 = 20.8 pounds
Each container can store 2.5 pounds of rice.
Let x represent the number of containers.
The number of containers that can be filled = 20.8/2.5 = 8.32
So, the maximum number of containers the chef will be able to fill with rice is 8

Answer: $124.50
Step-by-step explanation:
We are given that the equation y=4.75x+20 gives the cost y of towing a car if the car is towed x miles.
To find the best estimate of the cost for towing a car 22 miles., we substitute x= 22 in the above equation, we get
Cost of towing a car 22 miles=[tex]y=4.75(22)+20=[/tex]
[tex]\rightarrow\ y=104.50+20=124.50[/tex]

The interest earned from above cash under simple interest will be:
S.I=(PRT)/100
S.I=3500*4.5/100*10=$1575
the total amount after 10 years will therefore be:
1575+3500
=$5075
The same amount if it was compounded annually, the amount after 10 years will be:
FV=P(1+r/100)^n
FV=3500(1+3.5/100)^10
FV=4,937.10
we therefore conclude that the answer is:
Edward must have earned simple interest while Martin earned compound interest.
