1. The point (4, -2) is reflected across the y - axis.
What is the coordinates of the point after the reflection?
2. The point (7, -4) is reflected across the x - axis.
What is the coordinates of the point after the reflection?
Final answer:
The reflection of point (4, -2) across the y-axis is (-4, -2), and the reflection of point (7, -4) across the x-axis is (7, 4).
Explanation:
When a point is reflected across the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. Therefore, the reflection of the point (4, -2) across the y-axis is (-4, -2).
Similarly, when a point is reflected across the x-axis, the y-coordinate changes sign while the x-coordinate remains unchanged. This means the reflection of the point (7, -4) across the x-axis is (7, 4).

A report card has six marks. The average of the first and second marks is 72%. The average of
the second and third marks is 75%. The average of the third and fourth marks is 77%. The
average of the fourth and fifth marks is 78%. The average of the fifth and sixth marks is 79%.
a) Determine the overall average. b) Determine the average of the first and sixth marks.
Answer:
a) Overall average = 76%
b) Average of first and sixth marks = 75%
Step-by-step explanation:
Let's call the marks a, b, c, d, e and f, in this order.
Then, we can write the following equations:
(a+b)/2 = 0.72 -> a + b = 1.44 (eq1)
(b+c)/2 = 0.75 -> b + c = 1.5 (eq2)
(c+d)/2 = 0.77 -> c + d = 1.54 (eq3)
(d+e)/2 = 0.78 -> d + e = 1.56 (eq4)
(e+f)/2 = 0.79 -> e+ f = 1.58 (eq5)
If we sum all equations, we have:
a + 2b + 2c + 2d + 2e = f = 7.62 (eq6)
Then, we make (eq6) - (eq2) - (eq4):
a + b + c + d + e + f = 4.56 (eq7)
a) The find the overall average, we just need to divide (eq7) by 6:
Overall average = (a + b + c + d + e + f)/6 = 0.76 = 76%
b) First we need to make (eq7) - (eq2) - (eq4):
a + f = 1.5
Then, the average is:
Average = (a+f)/2 = 0.75 = 75%
Final answer:
The overall average of the six marks is 63.5%, and the average of the first and sixth marks is 75.5%. The calculation involves setting up algebraic equations from the given average pairs and solving for the totals and individual marks.
Explanation:
To calculate the overall average and the average of the first and sixth marks, we need to use some algebra. Since we know the average of the first two, second two, and so on, we can set up equations to find the individual scores.
Let the individual marks be represented as A, B, C, D, E, and F. From the given information, we can say:
(A + B) / 2 = 72
(B + C) / 2 = 75
(C + D) / 2 = 77
(D + E) / 2 = 78
(E + F) / 2 = 79
To find the overall average, sum all equations:
A + B = 144
B + C = 150
C + D = 154
D + E = 156
E + F = 158
Adding all these together, we get 2(A + B + C + D + E + F) = 762. Then, the total sum of the six marks A + B + C + D + E + F = 381. The overall average is 381 divided by 6, which equals 63.5%
To find the average of the first and sixth marks, we can use the first and last equations we have set up:
A + B = 144
E + F = 158
Now we add the two to get A + B + E + F = 302. However, we need only the sum of A and F. Since A + B + C + D + E + F = 381, we can subtract the sum of B, C, D, and E, which we find from the other equations:
Subtract (B + C + D + E) from 381 (Total sum), we get:
381 - (150 + 154 + 156)/2 = 381 - 230 = 151
This leaves A + F = 151. Dividing by 2, we get that the average of the first and sixth marks is 75.5%
Write 0.46 as a fraction simplest form
Answer:
23/50
Step-by-step explanation:
.46
There are 2 numbers after the decimal so we put it over 1 plus 2 zero's
46/100
Divide the top and bottom by 2
46/2 = 23
100/2 = 50
23/50
This is simplest form since 23 is prime and it does not go into 50 evenly

help me guys 64−(3y+8y+y)÷40=37
Answer: -118
Step-by-step explanation:
first multiply by 40. 37x 40 is 1480. No subtract 64 from both sides (1416). Multiply both sides by negative one to make the parentheses positive. -(1416)
on the inside that would be 12y so divide -1416 by 12 which is -118
I hope that's right!! :)

Answer:
32.59
That's what my calculator said
also I use acellus too Hi friend!
Answer:
32.59
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio )
4[tex](\frac{8}{9}) ^{n-1}[/tex] ← is the n th term expression
with a = 4 and r = [tex]\frac{8}{9}[/tex]
The sum of n terms of a geometric sequence is
[tex]S_{n}[/tex] = [tex]\frac{a(1-r^n)}{1-r}[/tex], thus
[tex]S_{20}[/tex] = [tex]\frac{4((1-\frac{8}{9}) ^{20}) }{1-\frac{8}{9} }[/tex]
= [tex]\frac{4(1-\frac{8^{20} }{9^{20} } )}{\frac{1}{9} }[/tex]
= 36( 1 - 0.0948)
= 36(0.905)
= 32.59 ( to the nearest hundredth )

in circle K, points A, B, and C lie on the circle. Which of the following would not be a chord of the circle?
(1) AC
(3) KC
(2) BC
(4) AB
(3) KC
Step-by-step explanation:
This is because KC would be a radius and a radius has one end point on the circle while the other is inside. Chords would have both endpoints on the circle.
Final answer:
The segment KC is not a chord of circle K because the center of a circle is not on the circumference, thus KC does not connect two points on the circle's edge like AC, BC, and AB.
Explanation:
A chord in a circle is defined as a line segment with both endpoints on the circle. Given a circle K with points A, B, and C on its circumference, the line segments AC, BC, and AB would all be considered chords of circle K, because they connect two points on the circle's circumference. However, KC cannot be a chord because point K is described as the center of the circle, not a point on its circumference.

Step-by-step explanation:
graphing rational functions
1
The horizontal asymptote is at y=4, shown by the green dashed line. This indicates the behavior of the function as x becomes very large in magnitude.
The blue dot marks the y-intercept at (0,6).
To find the graph that represents the function [tex]\( f(x) = \frac{2}{x-1} + 4 \)[/tex], let's analyze its characteristics step by step:
1. Identify the Type of Function
The function [tex]\( f(x) = \frac{2}{x-1} + 4 \)[/tex] is a rational function, specifically a transformed version of the reciprocal function.
2. Vertical Asymptote
The denominator [tex]\( x - 1 = 0 \)[/tex] gives the vertical asymptote, which is [tex]\( x = 1 \)[/tex]. This means the graph will approach but never touch the line [tex]\( x = 1 \)[/tex].
3. Horizontal Asymptote
For large values of x, the term [tex]\( \frac{2}{x-1} \)[/tex] approaches zero. Thus, the horizontal asymptote is determined by the constant term, which is [tex]\( y = 4 \)[/tex].
4. Y-Intercept
To find the y-intercept, set [tex]\( x = 0 \)[/tex]:
[tex]\[ f(0) = \frac{2}{0-1} + 4 = 2 + 4 = 6 \][/tex]
So, the y-intercept is at (0, 6).
5. Behavior around Asymptotes
As x approaches 1 from the left, [tex]\( f(x) \)[/tex] goes to negative infinity.As x approaches 1 from the right, [tex]\( f(x) \)[/tex] goes to positive infinity.6. Additional Points
It might be helpful to calculate the function's value at a couple of additional points for a more accurate graph. For instance, calculate [tex]\( f(2) \)[/tex] and [tex]\( f(-1) \)[/tex].
7. Sketching the Graph
Considering these characteristics, the graph:
Has a vertical asymptote at [tex]\( x = 1 \)[/tex].Has a horizontal asymptote at [tex]\( y = 4 \)[/tex].Passes through the y-intercept at (0, 6).Shows the function going to negative infinity as x approaches 1 from the left and to positive infinity as x approaches 1 from the right.Here is the graph of the function [tex]\( f(x) = \frac{2}{x-1} + 4 \)[/tex]. As analyzed:
(Graph is give below)
It has a vertical asymptote at x=1, represented by the red dashed line. The function goes to negative infinity as x approaches 1 from the left and to positive infinity as x approaches 1 from the right.
The complete question is here:
Which graph represents the function [tex]$f(x)=\frac{2}{x-1}+4$[/tex] ?

Answer B is correct.
Which of the following is the linear parent function?
A. F(x) = x
B. F(x) = x + 1
C. F(x) = 1/x
D. F(x) = x^2
Option A, F(x) = x, is the correct linear parent function because it represents a straight line with a slope of 1 that passes through the origin.
The linear parent function is the simplest form of a linear equation, which is described by a straight line with a slope of 1 and goes through the origin (0,0) on a coordinate plane. Among the options given, the correct answer is A. F(x) = x. This function represents a straight line that has a slope (gradient) of 1 and passes through the origin, making it the parent function for all linear equations. Options B, C, and D are not linear parent functions; B represents a linear function with a y-intercept of 1, C is a reciprocal function, and D is a quadratic function.

5/12 = x/15
Answer: 6.25.
Step-by-step explanation:
Let's put your question into a proper proportional form, because it is a ratio that is equal.
[tex]\frac{5}{12} = \frac{x}{15}[/tex]
To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.
[tex]5 * 15 / 12 = 6.25[/tex]
The answer you should get by doing this is 6.25.
Answer:
x=6.25
Step-by-step explanation:
Cross multiply
5/12=x/15
12*x=15*5
12x=75
Divide both sides by 12 to isolate the variable x
x=6.25
Or, multiply both sides by 15 to "reverse" the division being done to x
5/12=x/15
15*5/12=x/15*15
6.25=x

There will be 8 grams left after 36 minutes.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. in this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
36mins/16mins = 2 half lives.
now we can raise 1/2 to the power of how many half lives we have (2). then we multiply that by the amount in the sample.
(1/2)^2 * 36
1/4 * 36
8 grams

The number 50 is 5 times as many as 10?
Answer:
yes you are correct 50 is 5 times as many as 10 because 10 times 5 is 50 thank me later
Step-by-step explanation:
The statement is indeed correct: 50 is 5 times as many as 10. This understanding comes from the powers-of-ten notation system. We can also relate this to the concept of order of magnitude; the order of magnitude of 50 is 10², providing an approximation of its size in powers of ten.
Explanation:The question is asking if the number 50 is 5 times as many as 10. In mathematics, if you multiply 10 by 5, you do get 50, so the statement is indeed correct. This concept is part of multiplication and understood by using the powers-of-ten notation system, which is based on increases of ten.
The powers-of-ten notation system is the basis of our counting system, where each digit's place is ten times greater than the digit to its right. This notation system is used because humans have ten fingers and started counting with them.
An interesting approach is to relate this to order of magnitude. The order of magnitude of 50 is 10² because it's closer to 10² (100) than 10³ (1000). The order of magnitude only changes when you pass the square root of 10 (~3.16). Since 5 is greater than 3.16, when you multiply it by 10, it surpasses 10² (100), giving the order of magnitude as 10³. This is slightly off from the actual value of 50, illustrating how order of magnitude provides an approximation, not an exact value.
