Point M(-6,8) is dilated from the origin with a scale factor of 1/2. What is the coordinate of M'? *
Point M(-6,8) is dilated from the origin with a scale factor of 1/2, hence the new point is M'(-3, 4)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).
Given Point M(-6,8) is dilated from the origin with a scale factor of 1/2, hence the new point is at:

The cost of 2 tables and 3 chairs is $705. If the table costs $40 more than the chair, how much does a table cost?
Answer:
Step-by-step explanation:
2 tables and 3 chairs is $705
Let t stand for table and c stand for chair
3c + 2t = 705
We are told that the table costs $40 more than the chair, so t = c + 40
Now we can insert this into the equation
3c + 2(c + 40) = 705
The next step is to distribute the 2
3c + 2c + 80 = 705
Then combine like terms
5c + 80 = 705
To get the variable by itself, you have to subtract the 80 from both sides.
5c = 705 - 80
5c = 625
This means that 5 chairs costs $625.
Divided both sides by 5 to isolate the variable
c = 625/5
c = 125
Great, now you know the cost of one chair, $125!
The question is asking how much a table costs, and we know that a table costs $40 more than a chair.
A table costs $125 + $40
A table costs $165
Hope this helps! =)
Determine the inverse of the function f (x) = 3(x − 4)^2 + 5.
Step-by-step explanation:
since g(f(x)) = x g (f (x) )= x, f - 1 (x) = 5x3 + 43 f - 1 (x) = 5 x 3 + 4 3
The inverse of the given function [tex]f(x) = 3(x-4)^{2} +5[/tex] is [tex]f^{-1} (x) = \sqrt{\frac{x-5}{3} } +4[/tex].
What is the inverse of a function?An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by [tex]f^{-1}[/tex] or [tex]F^{-1}[/tex].
According to the given equation.
We have a function.
[tex]f(x) = 3(x-4)^{2} +5[/tex]
The above function can be written as
[tex]y = 3(x-4)^{2} +5[/tex]
Write the above function for x.
[tex]\implies y -5 = 3(x-4)^{2}[/tex]
[tex]\implies \frac{y-5}{3} = (x-4)^{2}[/tex]
[tex]\implies \sqrt{\frac{y-5}{3} } =x-4[/tex]
[tex]\implies \sqrt{\frac{y-5}{3} } +4=x[/tex]
[tex]0r\ x = \sqrt{\frac{y-5}{3}}+4[/tex]
Replace [tex]x[/tex] by [tex]f^{-1}(x)[/tex] and [tex]y[/tex] by [tex]x[/tex].
We get
[tex]f^{-1} (x) = \sqrt{\frac{x-5}{3} } +4[/tex]
Hence, the inverse of the given function [tex]f(x) = 3(x-4)^{2} +5[/tex] is [tex]f^{-1} (x) = \sqrt{\frac{x-5}{3} } +4[/tex].

Third question.
A circle's circumference is 43.96 cm. what is the length of the circles diameter?
Answer:
1. x=105
2. 12 cans for $4
3. 14
Step-by-step explanation:
1. 15/18 = x/126
126/18=7
x=15*7=105
2. 12 cans for $4. 36 for $11.50.
36/3=12. 11.50/3=3.8333.
12 cans for $4 is the better deal because it would be an equal deal if it was 36 for 12:00.
3. Circumference = pi*d. Circumference = 43.96. pi=3.14. 3.14*x=43.96. x=diameter. x=14. diameter = 14
--Explanation to 3.14*x=43.96:
3.14*x=43.96, = 3.14x=43.96
3.14x*100 =43.96*100
314x=4396
314x/314 = 4396/314
