Answer:
Reflection about the y-axis is according to the rule
(x,y)->(-x,y)
Therefore F(x,y) -> F'(-x,y)
The distance between F' and F is (-x,y)-(x,y)=-2x, or the positive distance is 2x.

Given that (1, 0, 1) is a solution to a system of three linear equations, which of the following is true about the system?
The system can be either inconsistent or consistent.
The system can be either independent or dependent.
The system can only be independent and consistent.
The system can only be dependent and inconsistent.
===========================================================
Explanation:
Let's go through the answer choices
A) This isn't possible. Either a system is consistent or inconsistent. It cannot be both at the same time. The term "inconsistent" literally means "not consistent". It's like saying a cup is empty and full at the same time. We can rule out choice A.B) This is similar to choice A and we cannot have a system be both independent and dependent. Either a system is independent or dependent, but not both. Independence means that the two equations are not tied together, while dependent equations are some multiple of each other. We can rule out choice B.C) We'll get back to this laterD) The independence/dependence status is unknown without the actual equations present. However, we know 100% that this system is not inconsistent. This is because the system has at least one solution. Inconsistent systems do not have any solutions at all (eg: parallel lines that never cross). We can rule out choice D because of this.Going back to choice C, again we don't have enough info to determine if the system is independent or dependent, but we at least know it's consistent. Consistent systems have one or more solutions. So part of choice C can be confirmed. It being the only thing left means that it has to be the final answer.
If it were me as the teacher, I'd cross out the "independent" part of choice C and simply say the system is consistent.
Answer:
Above that (1, 0, 1) is a solution to a system of three linear equations, The system can only be independent and consistent. is true about the system.

Answer:
$1251.59
Step-by-step explanation:
tax percent = 6.7%
cost price of watch = $113
tax amount = tax percent of total price
=6.7 % * 1173
=6.7/100 *1173
=78.591
Now find total cost of a watch with tax
total cost = tax amount + original cost price
=$78.591 + $1173
=$1251.59
Please help im confused i was not here today.. Please reflect (-4,-3)??.
Can you solve this graph problem?
a) what is the difference in temperatures between 7 am to 5 pm
b) which part of the day was the temperature rising the fastest a, b, c, d, or e?
Answers:
a) The difference in temperature is 25 degrees Fahrenheit. b) The temperature was rising fastest during interval 'a'=========================================================
Explanations:
a) We subtract the y coordinates of the left and right endpoints. We get 65-40 = 25b) The fastest rising temperature will visually correspond to the steepest part of the curve. That would be region 'a'. After this interval, region b is still increasing, but not as much as the previous interval (since it's not as steep here). Then it gets less steep for region c, and d sort of flattens out as well. So during the morning hours it appears the temperature is going up the fastest.help me with this please
Answer:
Perimeter= 20 cm
Area = 25 cm^2
Difference between 28cm^2 and 8cm^2= 20cm^2
Step-by-step explanation:
The formula to calculate the perimeter of a square is P= 4 * (the length of any side or "s").
Therefore:
P = 4 * 5cm
P = 20 cm
The formula for calculating the area of a square is A= (length of any side or "s")^2
So:
A= 5cm^2
A= 25cm^2
Remember the units in your answer!
The difference between indicates subtraction, and 28cm^2 and 8 cm^2 are like terms so:
28cm^2 - 8 cm^2 = 20 cm^2

need help on trigonometry again
Answer:
[tex]\fbox{3\sqrt{2}}[/tex][tex]3\sqrt2[/tex]
Step-by-step explanation:
Step 1:
Let us figure out the measurements of all the angles first. We are given one angle of 45º, and another of 90º. The angles of a triangle must add up to 180º, hence we can use basic addition and subtraction to find the last angle.
[tex]\angle=180-90-45\\\angle=45[/tex]
Great our angle is 45º! Notice something...?
Step 2:
We now have two 45º angles in our triangle. This means we have an isosceles triangle.
According to BATh (base angle theorem), in an isosceles triangle, the angles opposite the congruent sides are congruent. Thus, y is congruent to the given side of [tex]3\sqrt2[/tex].
y=[tex]\fbox{3\sqrt{2}}[/tex][tex]3\sqrt2[/tex]

Answer:
option B
Step-by-step explanation:
Given :
[tex]y = \frac{2}{3}x + 3\\\\y = \frac{5}{2}x + \frac{7}{2}\\\\[/tex]
Step 1 : simplify the equation :
[tex]3y = 2x + 9\\\\2y = 5x + 7\\[/tex]
Step 2: Arrange the terms :
[tex]2x - 3y = - 9\\\\5x -2 y = -7[/tex]
Step 3 : Solve for x and y :
2x - 3y = - 9 ------ ( 1 )
5x - 2y = - 7 --------- ( 2 )
_____________________
( 1 ) x 5 => 10x - 15y = - 45 ---------- (3 )
( 2) x 2 => 10x - 4y = - 14 ----------- (4 )
_______________________
( 3 ) - ( 4 ) => 0x - 11y = - 31
- 11 y = - 31
[tex]y = \frac{31}{11}[/tex]
Substitute y in ( 1 ) :
2x - 3y = - 9
[tex]2x - 3 (\frac{31}{11}) = - 9\\\\2x = -9 + 3(\frac{31}{11})\\\\2x = - 9 + \frac{93}{11}\\\\2x = \frac{-99 + 93}{11} \\\\2x = \frac{-6}{11} \\\\x = \frac{-6}{2 \times 11} = -\frac{3}{11}[/tex]
Therefore the solution to the sytem is [tex]( - \frac{3}{11} , \frac{31}{11})[/tex]
The solution of the system of equation is a point which lies
on the both the lines.
Option A : False , It says the solution lies above one of the given line.
But the solution of the system of equation always lies on
both the line.
Option B : True , says the solution is a point on the coordinate plane.
Option C : False, because if the solution is on the x-axis , then
the y coordinate in the solution would be zero.
But it is not zero.
Option D : False , the solution is the point where both the lines intersect.

What are Trigonometric Ratios?Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.
A right angled triangle is a triangle with measure of one of the angle as 90 degree.
The triangle XYW is a right triangle, with right angle at W.
The measure of angle X is f degrees and the measure of angle Y is d degrees.
The value of the trigonometric ratio sin f = 8/9
The measure of segment YW is 24 units,
The sin of an angle is the ratio of Perpendicular to the angle and the hypotenuse of the triangle.
sin f = YW / XY
8/9 = 24 / XY
XY = 24 * 9/8
XY = 27 °
The value of YX has been determined.

Alternate Exterior Angles?
Please helpppp
Answer:
1 and 8, 4 and 5
Step-by-step explanation:
There are two pairs, 1 and 8, 4 and 5
The angles in each pair must be on opposite sides of the transversal k, and on the outsides of the parallel lines l and m.
What is the answer for K ?
10/3 = k/9
10 x 9 = 3 x k
90 = 3 k
k = 90/3
k = 30
The quadrilateral ABCD is a parallelogram.
The value of a is?
Step-by-step explanation:
in a parallelogram, opposite angles are equal..
so C is 4a + 22. and B is 6a - 12.
sum of interior angles in a quadrilateral = 360
4a + 22. + 6a - 12. + 4a + 22. + 6a - 12 = 360
20a + 20 = 360
20a = 340
a = 17
sum of angles on a straight line = 180
B + x = 180
6 ( 17) - 12 + x = 180
102 + × = 180
× = 180 - 102
× = 78
Annie buys some greeting tickets cards. Each card costs $1.75. She pays with with a twenty dollor bill. Let N represent the number of greeting cards annie buys. Write an expression that represents the amount of change annie shall receive.
Answer:
$20 - $1.75N
Step-by-step explanation:
the amount of change she receives is equal to the amount she paid less the total value of cards
total value of cards = price per card x total quantity of cards bought
$1.75 x N = $1.75N
Amount of change = $20 - $1.75N
If she buys 10 cards, the amount of change she receives would be
$20 - $1.75(10) =
20 - 17.5 = 2.5
Help me please !!!!! ASAP !
Answer:
x = 6 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2+ x^2 = 12^2
36 + x^2 = 144
Subtract 36 from each side
x^2 = 144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(36*3)
x = 6 sqrt(3)

Answer:
The cylindrical one
Step-by-step explanation:
We know that the container does not have anything inside it, and we only want the surface, so we will figure out the surface area. The less surface area the package has, the less plastic is used.
The surface area for a cylinder is 2πrh +2πr². Plugging 5 in for r (the radius) and 19 in for the height, we get
2π(5)(19) + 2π(5)² = 753.98
The surface area for a rectangular prism is 2(wl + hl +hw), with 10 being the width, 12 being the length, and 19 being the height in this example, resulting in
2(10*12 + 19 * 12 + 10 * 19) = 1076
The surface area for the cylinder will clearly have less surface area/plastic

How do you multiply 14.60 * 870
Answer:
12702
Step-by-step explanation:
Since there are 2 digits after the decimal in 14.60, add a decimal to the 870 and put two 0s after it (So it looks like this 870.00)
Then put the two numbers on top of each other, make sure to line up the decimals and multiply normally. When you're done, you should come out with the number 127020000. Since there is 2 digits behind the first number and 2 digits behind the second number, resulting in 4 digits, you're gonna count 4 numbers from the back of your answer and put a decimal there (so it is now 12702.0000) but you don't really need those 0s there so you can just remove them. (Answer 12702)
Hope this helped. If not, search up "Multiply a Whole Number by a Decimal | Math with Mr. J" it might explain better
Question 4 of 12
Write a point-slope equation for the line that passes through the point (1, 22)
and is parallel to the line given by y = 14x-3. Do not use parenthesis on the y
side.
Answer:
y - 22 = 14(x - 1)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 14x - 3 ← is in slope- intercept form
with slope m = 14
Parallel lines have equal slopes
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 14 and (a, b) = (1, 22) , then
y - 22 = 14(x - 1)
