Answer:
-no answer-
Step-by-step explanation:
Use elimination (subtract one equation from the other to get rid of one of the variables)
x+2y=1
- -x+2y=0
--------------------
---=1
(nothing equals one)
so this is not a valid system of equations.

What is the distance between 4 and 17?
Answer:
14
Step-by-step explanation:
17 - 4 + 1 = 13 + 1 = 14
Answer:
Step-by-step explanation:
D = distance
[tex]x_{1}[/tex] = 4
[tex]x_{2}[/tex] = 17
No "y" values were given.
The distance formula:
[tex]D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}[/tex]
If we insert in the values:
[tex]D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}[/tex]
(0-0)^2 = 0 so we can just remove the last part since it's +0:
[tex]D = \sqrt{(4 - 17)^{2}}[/tex]
4 - 17 is equal to -13:
[tex]D = \sqrt{(-13)^{2}}[/tex]
Since [tex](-a)^{2} = (a)^{2}[/tex], that means that the negative 13 becomes positive
[tex]D = \sqrt{(13)^{2}}[/tex]
Now the square root and the square cancels each other out:
[tex]D = 13[/tex]

What is the value of x2+9x+20 when x could be -5, -3 or -6
Answer:
Step-by-step explanation:
You should use a ^ to indicate an exponent. x^2 is the same as x².
x² + 9x + 20
Replace the x with (-5).
(-5)² + 9(-5) + 20 = 25-45+20 = 0
Then do the same with x = (-3):
(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2
You can do x = (-6)

annually. How much would Madeline need to invest, to the nearest ten dollars, for
the value of the account to reach $16,600 in 12 years?
Answer:
$9540
Step-by-step explanation:
A = P(1 + r)^t
16600 = P(1.044)^12
P = 16600/(1.044)^12
P = $9,543.64

ABCD- parallelogram, If the perimeter of Triangle CPQ is 15cm, Find the perimeter of triangle BAQ. Find the perimeter of triangle PDA. PLEASE FIND THE ANSWER QUICKLY I NEED IT RIGHT NOW
Answer:
The answer is below
Step-by-step explanation:
A parallelogram is a quadrilateral (has 4 sides and 4 angle) with two pair of parallel and opposite sides. Opposite sides of a parallelogram are parallel and equal.
Given parallelogram ABCD:
AB = CD = 18 cm; BC = AD = 8 cm
∠P = ∠P, ∠PDA = ∠PCQ (corresponding angles are equal).
Hence ΔPCQ and ΔPDA are similar by angle-angle similarity theorem. For similar triangles, the ratio of their corresponding sides equal. Therefore:
[tex]\frac{CD}{PC}= \frac{AD}{CQ}\\\\\frac{18}{6}=\frac{8}{x} \\\\x=\frac{6*8}{18}=\frac{8}{3}\ cm[/tex]
Perimeter of CPQ = CP + CQ + PQ
15 = 6 + 8/3 + PQ
PQ = 15 - (6 + 8/3)
PQ = 6.33
∠CQP = ∠AQB (vertical angles), ∠QCP = ∠QBA (alternate angles are equal).
Hence ΔCPQ and ΔABQ are similar by angle-angle similarity theorem
[tex]\frac{AQ}{QP}=\frac{AB}{CP} \\\\\frac{AQ}{6.33} =\frac{18}{6} \\\\AQ=\frac{18}{6}*6.33\\\\AQ = 19[/tex]
[tex]\frac{BQ}{CQ}=\frac{AB}{CP} \\\\\frac{BQ}{8/3} =\frac{18}{6} \\\\BQ=\frac{18}{6}*\frac{8}{3} \\\\BQ =8[/tex]
Perimeter of BAQ = AB + BQ + AQ = 18 + 8 + 19 = 45cm
PA = AQ + PQ = 19 + 6.33 = 25.33
PD = CD + DP = 18 + 6 = 24
Perimeter of PDA = PA + PD + AD = 24 + 25.33 + 8 = 57.33 cm

Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
The question is incomplete. The complete question is :
Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
Where, if any, did Basil first make a mistake in his work?
Solution :
Not -- Basil did not make any mistakes in his work. He found out the perimeter of an enlarged shape.
Perimeter is the total measure of the outer lining or the total outer length of the body or the shape. For different shapes, the perimeters will be different. Basil measure the outer length of the body and found out the perimeter.

A new car is purchased for 24600 dollars. The value of the car depreciates at 5.5% per year. To the nearest year, how long will it be until the value of the car is 11300 dollars?
Answer:
The number of years until the value of the car is 11300 dollars is 9 years.
Step-by-step explanation:
This can be calculated using the following formula:
Value of the Car = Purchase cost - (Annual depreciation expenses * N) ........ (1)
Where;
N = Number of years until the value of the car is 11300 dollars
Purchase cost = $24,600
Annual depreciation rate = 5.5%
Annual depreciation expenses = $24,600 * 5.5% = $1,353
Value of the car = $11,300
Substituting the value into equation (1) and solve for N, we have:
$11,300 = $24,000 - ($1,353 * N)
$1,353 * N = $24,000 - $11,300
$1,353 * N = $12,700
N = $12,700 / $1,353
N = 9.38654841093865
Rounding to the nearest year as required by the question, we have:
N = 9
Therefore, the number of years until the value of the car is 11300 dollars is 9 years.

Which bag gives you more free rice.
Show your working.
Answer: rice a
Step-by-step explanation:
convert 1/5 to a decimal .20 <.25
Bag of rice B gives more rice than bag A as per the percentage.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
Given, A shop sells two different bags of rice. Rice A has 500g plus 25% extra free and Rice B has750g plus 1/5 extra free.
For calculating the free amount of rice,
For Bag A
Frre amount of rice = 500* 25% = 500 *25/ 100 = 125g
For Bag B
Frre amount of rice = 750 * 1/5 = 150g
Therefore, According to the percentage, bag B of rice contains more rice than bag A.
