Write a rule in function notation to describe the transformation that is a reflection across the x-axis.
Answer:
R(x, y) = (x, -y)
Step-by-step explanation:
When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.
For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.
So if we have a point like (4, 7)
Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)
Here we already can see the rule.
If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)
Then we can write this reflection as a function in the next way:
R(x, y) = (x, -y)
This means that if the input is the point (x, y), the output is the point (x, -y)

Payday loans are typically $15 charge with an interest rate of 10% over a 2 wk period which variables in the interest formula are known
Answer:
Time = period of loan
Interest amount = $15
Interest rate = 10%
Step-by-step explanation:
Given:
Charge on loan = interest = $15
Interest rate on loan = 10%
Loan period = 2 weeks
The interest formula is given by the relation :
Interest = Principal * rate * time
Using the interest equation given :
The known variables Given in the question are :
Time = period of loan
Interest amount = $15
Interest rate = 10%

3. A circle with center (0,0) has a y-intercept at (3,0).
Find the equation of the circle.
Answer:
x^2 + y^2 = 9
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here h = 0, k = 0, x = 3 and y = 0:
(3 - 0)^2 + (0 - 0)^2 = r^2, or
9 = r^2. Thus, the radius is 3.
The equation of this circle is (x - 0)^2 + (y - 0)^2 = 9, or
x^2 + y^2 = 9

If beaver family one can cut down and 20" tree in 15 minutes and family two can cut down a tree 3 times the size in twice as long how long will it take the second beaver family to cut down a 20" tree
Answer:
10 minutes
Step-by-step explanation:
Beaver family 2 can cut down 60'' (20 x 3) tree in 30 (15 x 2) minutes
In one minute, beaver family 2 would cut down 60/30 = 2'' tree
time to cut down 20'' tree = 20/2 = 10 minutes

A box in the shape of a rectangular prism has the dimensions shown. What is the length of the interior diagonal of the box? Round to the nearest tent
Enter your answer in the box.
Answer:
141.4 cm
Step-by-step explanation:
Refer to the notations in the attached photo,
AG = d
Using Pythagoras Theorem:
In triangle ABC,
AC
=[tex] \sqrt{ {60}^{2} + {80}^{2} } [/tex]
=[tex] \sqrt{3600 + 6400} [/tex]
=[tex] \sqrt{10000} [/tex]
= 100 cm
∴ AC is 100 cm.
In triangle ACG,
d
=[tex] \sqrt{ {100}^{2} + {100}^{2} } [/tex]
=[tex] \sqrt{10000 + 10000} [/tex]
=[tex] \sqrt{20000} [/tex]
= 141.4 cm (cor. to the nearest tenth)
Sheila is twice as old as Rita. In two years, Sheila will be four times as old as Rita was nine years ago. How old is each now?
Answer: (Sorry for not wording it correctly I had to reword it)
Step-by-step explanation: Let R be the current age of Rita. Let S be the current age of her son.
Rita is twice as old as her son.
=> R = 2S
In 4 years, R will be 4 times as old as S was 9 years ago
=> R + 4 = 4 (S - 9)
Solve for R, and S:
=> R + 4 = 4 (S - 9)
=> (2S) + 4 = 4(S - 9)
=> 2S + 4 = 4S - 36
=> 2S - 4S = -36 - 4
=> -2S = -40
=> S = 20
Find R:
=> R = 2S
=> R = 2(20)
=> R = 40
Therefore, Rita is 40, her son is 20.

Can someone really help me!
Answer:
Step-by-step explanation:
3x - (3x) - 2 = 3x + 3x - 2 {Combine like terms}
= 6x - 2
I-100I + 3x - [-4x] = 100 + 3x + 4x
= 100 + 7x
I -100 I means absolute value of 100 = 100

Find the equation of the straight line having a slope root 3 and passing through the point(-1,5)
Given:
Slope of a straight line is [tex]\sqrt{3}[/tex].
The line passing through the point (-1,5).
To find:
The equation of the straight line.
Solution:
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.
The line passing through the point (-1,5) with slope [tex]\sqrt{3}[/tex]. So, the equation of the line is:
[tex]y-5=\sqrt{3}(x-(-1))[/tex]
[tex]y-5=\sqrt{3}(x+1)[/tex]
[tex]y=\sqrt{3}x+\sqrt{3}+5[/tex]
Therefore, the equation of the straight line is [tex]y=\sqrt{3}x+\sqrt{3}+5[/tex].

Please help out it’s math homework thank you for all your help !
Answer:
71°
Step-by-step explanation:
Remember, all the interior angles of a triangle add up to 180 degrees. Therefore, we can find the value of x by subtracting the values of the other angles from 180:
x=180-82-27
x=71
