Which equation describes a line of symmetry for rectangle ABCD
Answer:
C. [tex] x = -2 [/tex]
Step-by-step explanation:
A rectangle has two lines of symmetry. That is, the line that divides the rectangle into two equal halves.
Taking a look at the rectangle that is placed on the coordinate grid. At what points do you think the two lines of symmetry can be located at that will give us two possible equal halves?
One will be horizontal, the other will be vertical.
For the horizontal line, the line of symmetry can be located at y = 5. If an horizontal line cuts through the rectangle at y = 5, we would have two equal halves.
Thus, an equation for a horizontal line is often represented as [tex] y = k [/tex]. Where k is a constant, because every coordinate point on the horizontal line would have the same value of k, which is where the line cuts across the y-axis. The slope of am horizontal line remains zero also.
Therefore, the equation of the line of symmetry of the rectangle shown in the coordinate grid would be:
✅[tex] y = 5 [/tex]
The second line of symmetry which is vertical, would cut across the rectangle at x = -2.
Thus, the slope of a vertical line is undefined.
The equation of a vertical line is represented as x = h.
Where h is a constant, since all coordinates along the vertical line would surely have a x-coordinate value of -2, regardless of what y-coordinate value they have.
Therefore, h, in this case is -2.
Thus, the equation that represents the second line of symmetry of the rectangle above would be:
✅[tex] x = -2 [/tex].
The two equations that represent the two lines of symmetry of the rectangle, respectively, are:
[tex] y = 5 [/tex]
[tex] x = -2 [/tex]
From the options given, the only correct option provided is:
[tex] x = -2 [/tex].

3y=18x+6
3y-18x=12
Regroup:
18x-3y=-6
-18x+3y=12
Add:
0=6???
Impossible
So no solution.
Hope this helps plz mark brainliest :D
Answer:
No solution
Step-by-step explanation:
First we need to solve the equations.
I'll use the combining method
To do the combining method you need to get one of the variables in the first equation to be the negative correspondent to the same variable in the second equation.
(Ex:
If there was 2x in the first equation we would want there to be -2x in the second so they cancel out.)
y=6x+2
subtract 6x from each side to get the variables to line up
y-6x=2
3y-18x=12
To get -6x to equal 18x, we will multiply everything in the first equation by -3
-3y+18x=-6
3y-18x=12
Now combine the two terms
-3y and 3y cancel out
18x and -18x cancel out
-6+12=6
We are left with 0=6.
0 does not equal 6 so there is no solution.
Elena went to a sporting goods store that was having a sale. She bought a tennis ball and 3 cans of tenis balls The tennis racket normally cost $43. All tenis rackets are marked down 15%. One can of tens balls normally cost $4. The tenis balls are not marked down. The sales tax rate is 8.5% How much will she pay for everything including tax?
Answer: She will pay $52.68, including taxes
Step-by-step explanation: One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:
can = 3 x 4 = 12
One tennis racket is $43 but it has a discount of 15%:
discount = 0.15 x 43 = 6.45
total racket = 43 - 6.45 = 36.55
Elena will have to pay:
pay = 12 + 36.55 = 48.55
She will also have to pay taxes, which are 8.5% over the price she paid:
pay + tax = 48.55 x 0.085 = 4.13
total to pay = 48.55 + 4.13 = 52.68
Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
There are 30 popsicles in the
freezer
1⁄2 of them are cherry flavored The
rest are lime flavored.
How many are lime flavored?
Answer:
15 are lime flavored
Step-by-step explanation:
To find the answer you have to divide 30 by 2 to get 15.Because to find half of something you have to divide the number by two.

Eight times the difference of a number and three is sixty-four
Answer:
8 (n - 3) = 65
Step-by-step explanation:
the difference of a number and three means n - 3
8 times the difference of means that it will be 8 and then parenthesis the next terms that are said, so 8 (?)
is sixty-four means = 64
so put it together and you have 8 (n - 3) = 65
theres a photo with the question <3
Answer:
p≤1 or p∠-2
Step-by-step explanation:
REMEMBER OUR GOAL IS TO LEAVE P ALONE!!
p≤1:
1. [tex]\frac{3p+5}{2}\geq 4[/tex] Multiply by 2 to cancel out 1/2 which would give you [tex]{3p+5}\geq 8[/tex]
2. Then subtract 5 which would give you 3p≥3
3. Then divide by 3 which will FLIP the ≥ into ≤.
4. Therefore, it's p≤1.
p∠-2:
1. [tex]\frac{p-6}{4}\leq -2[/tex] Multiply by 4 to cancel out the denominator which would give you [tex]p-6[/tex]∠-8
2. Add 6 to both sides which results in p<-2

What is the y-intercept of the equation: 3x+6y=42
what is the slope of the line that passes through the points (48,10) and (-36,17)
Answer:
slope is -1/12
Step-by-step explanation:
slope =y2 - y1 / x2-x1
Find the slope of each line
answer: 4
explanation: it would be 4 because slope is rise/run and it rises 4 and runs one so u would get 4/1 which is 4 simplified. :)
Answer:
Slope: 4
Step-by-step explanation:
The slope is 4, because each time x is increased by 1 y is increased by 4.
The rise would be 4 and the run would be 1.
Since the slope of a graph can be found by dividing rise by run, the slope would be 4/1, which is equal to 4.
The ratio of boys to total players in league soccer is 3:5. How many are there if there are 45 boys?
Answer:
Step-by-step explanation:
since 3 * 15 = 45, we know that we have to multiply 5 by 15. so the ratio would be 45:75. I hope this helps!
Answer
45:75
Step-by-step explanation:
The original ratio tells you there are 3 boys to 5 players total. If you divide the given amount of boys (45) by the original (3) then you get 15 (this is what you would use to find the players) 15 x 5= 75, so your answer is 45 boys to 75 players.

Expand.
Your answer should
be a polynomial in standard form.
(-a+1) (5a+6)
Answer:
-5a^2 - a + 6
Step-by-step explanation:
Now, I don't know if you have memorized this very niche trick in Algebra. Don't tell anybody I told you this, as the CIA will chase me down for allegedly sharing higher intelligence, but you can easily expand equations by the method of FOIL (FIRSTS, OUTSIDES, INSIDES, LASTS). Using this method, we multiply -a and 5a, -a and 6, 5a and 1, and 1 and 6. Adding them all together, our expanded form is -5a^2 - 6a + 5a + 6. Adding like terms, our final polynomial is -5a^2 - a + 6.
