A point has the coordinates (0, k).
Which reflection of the point will produce an image at the same coordinates, (0, k)?
Answer:
B
Step-by-step explanation:
I took the assignmen.
The reflection of point that will produce the image at same coordinate (0, k) is across the y - axis
We have a Point with coordinates (0, k).
We have to find the reflection that will produce the image at the same coordinate (0, k).
Consider a Point P (x, y). Find the image of the point across x - axis and y - axis.For a Point P [tex](x,y)[/tex] the image across -
x - axis is (x, -y).y - axis is (-x, y)We can use the above laws to find the reflection of point
For Point P(0,k) , the -
image across x - axis will be (0, -k).image across y - axis will be (-0, k), which is same as (0, k).Hence, the reflection of point that will produce the image at same coordinate [tex](0,k)[/tex] is across the y - axis.

Mr.V's trail mix uses 1/2cup of peanuts, 2 1/4 cups raisins, and he uses 2 times more sunflower seeds than raisins.How many total cups of trail mix can mix can Mr.V make
Answer:
The total number of cups is 9 1/2 cups
Step-by-step explanation:
Here, we are interested in calculating the total cups of trail mix that Mr V can make.
From the question, we are told that he used 1/2 cups of peanuts, 2 1/4 cups of raisins and 2 times more sunflower seeds than raisins.
So basically, we need to find the number of cups of sunflower seeds used.
The information we have here is that he used 2 times more of raisins;
Thus, the number of cups of sunflower would be 2 * 2 1/4 = 2 * 9/4 = 9/2. But practically is 9/2 , two times more than 2 1/4? NO!
What we should do here is to add 9/2 to 2 1/4. In that case, the difference between the two will be 2 times the cups of raisins;
So 9/2 + 9/4 = (18 + 9)/4 = 27/4
So the total number of cups of trail mix that can be made will be;
1/2 + 27/4 + 9/4 = (2 + 27 + 9)/4 = 38/4 = 19/2 = 9 1/2 cups

Answer:
x = [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Given
- 3 - 39x = 11x - 23 ( subtract 11x from both sides )
- 3 - 50x = - 23 ( add 3 to both sides )
- 50x = - 20 ( divide both sides by - 50 )
x = [tex]\frac{-20}{-50}[/tex] = [tex]\frac{2}{5}[/tex]
Markus decides to return 4 shirts costing $19 each to a clothing store. While there, he decides to purchase 2 pairs of shoes at $45 each and a raincoat for $62.75. The clerk charges him 5% tax on the amount due after returns. What amount does he owe the clerk?
Answer:
$80.59
Step-by-step explanation:
You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.
1. Numa escola de 670 alunos, 352 estudam Inglês, 125 fazem apenas o curso de Espanhol e 85 estudam as duas línguas. Com base nessas informações, determine: a) Quantos estudam Inglês ou Espanhol? b) Quantos fazem espanhol? c) Quantos não estudam nenhuma dessas línguas?
Answer:
a) Quantos estudam Inglês ou Espanhol?
477
b) Quantos fazem espanhol?
210
c) Quantos não estudam nenhuma dessas línguas?
193
Step-by-step explanation:
a) Quantos estudam Inglês ou Espanhol?
Inglês ou Espanhol = Quantidade de alunos que cursam inglês + Quantidade de alunos que cursam espanhol - Quantidade de alunos que cursam inglês e espanhol
= 352 + 210 - 85
= 477
b) Quantos fazem espanhol?
Isso é dado na pergunta como alunos que só aprendem espanhol = Somos informados de que o número de alunos que estudam apenas espanhol = 125
Número de alunos que cursam espanhol = Número de alunos que cursam apenas espanhol + Número de alunos que cursam espanhol e inglês
Número de alunos que fazem espanhol = 125 + 85
= 210 alunos
c) Quantos não estudam nenhuma dessas línguas?
Número total de alunos - (número de alunos que não cursam nenhum dos idiomas) = Número de alunos que cursam inglês + Número de alunos que cursam espanhol - Número de alunos que cursam os dois
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 352 + 210 - 85
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 477
Número de alunos que não cursam nenhum dos idiomas = 670 - 477
= 193 alunos
True or False, the chance of flipping heads on a coin 3 times in a row is 1/2
true flip a coin it's fifty fifty
Answer:
False
Step-by-step explanation:
Each toss is an independent event, so the probability of three tosses of heads in a row is the product of the three probabilities..
Each probability of heads is
p(heads) = 1/2
p(heads, heads, heads) = p(heads) * p(heads) * p(heads) = 1/2 * 1/2 * 1/2 = 1/8

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x
[tex]-22x+13=-31[/tex] subtract 13 on both sides
[tex]-22x+13(-13)=-31(-13)[/tex] cross out +13(-13) and -31-13= -44
[tex]-22x=-44[/tex] divide -22 on both sides

TOPIC: similtaneous linear equations
p1 + 2q = 3,
p - 2q = 3
Answer:
q-0
p-3
Step-by-step explanation:
there are two ways to solve elimination or substitution method I'll use the latter
so take the second equation and find an expression equal to p
p-2q=3
p=2q+3
substitute the above expression in the first equation
(2q+3)1+2q=3
open brackets
2q+3+2q=3
collect like terms
4q+3=3
solve
4q=0
q=0
substitute q in any equation you want I'll choose the second
p-(2×0)=3
p-0=3
p=3
Answer:
p = 3 ; q = 0
Step-by-step explanation:
In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that
[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-
[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )
Solving the eqn. gives,
[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]
Putting the value of q in any one of the linear eqn gives ,
[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]
What is the slope of the line that passes through the points (10,5) and (9,5)? Write
your answer in simplest form.
Answer:
slope of line is 0.
Step-by-step explanation:
Slope of a line passing through (x1,y1) and (x2,y2) is given by
m = (y2-y1)/(x2-x1)
Given points are (10,5) and (9,5)
thus
slope = (5-5)/(9-10) = 0/-1 = 0
Thus, slope of line is 0.
When slope of line is zero it means that the line the which passes through given point is parallel to x-axis.
The slope of the line that passes through the points (10,5) and (9,5) is 0.
Using slope formula,
m = y₂ - y₁ / x₂ - x₁
Therefore,
(10,5) (9,5)
m = 5 - 5 / 9 - 10
m = 0 / -1
m = 0
Therefore, the slope of the line that passes through the points (10,5) and (9,5) is 0.

Answer: [tex]\frac{8}{9}[/tex]
Step-by-step explanation:
When you multiply fractions, it is the same as adding or subtracting, but you don't have to worry about having a common denominator. All you have to do is multiply straight across and simplify.
[tex]\frac{4}{3}*\frac{2}{3} =\frac{8}{9}[/tex]
Now we know the answer is [tex]\frac{8}{9}[/tex].
Answer:
8/9
Step-by-step explanation:
The answer is 8/9 because:
1) Whenever we multiply fraction, we have to multiply the numerator and the denominator together: numerator x numerator/denominator x denominator
2) Therefore, 4 x 2/ 3 x 3 = 8/9
