Point M(-6,8) is dilated from the origin with a scale factor of 1/2. What is the coordinate of M'? *
Answers
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:

Answer:
the slope is -2
Step-by-step explanation:
Answer:
1/1 = 1
Step-by-step explanation:
Use rise/run.
The x value increases by 1 in the same amount of time that the y value increases by 1. This gives you the slope 1/1 (y increase/x increase).
1/1 can then be converted to 1.

I know the answer is 11, but how? When I did it, I got -29 and I don’t know how to get 11. Could someone explain step by step on how to get the correct answer?
Answers
5(-2)² - 9
First, solve the one in the bracket which is -2 × -2 which gives us =4
5(4) - 9
Then, multiply 5 with 4 so

½x - 5 = -6
Which solution makes this equation true?
1. -12
2. -2
Answers
Let’s try x = -12
1/2(-12) - 5 = -6
PEMDAS says to multiply first
1/2 x -12 = -6
So
-6 - 5 = -6
-6 - 5 = -11 not -6 so it’s not that
Now let’s do x = -2
1/2(-2) - 5 = -6
Again, you multiply first
1/2 x -2 = -1
-1 - 5 = -6 so it works

Third question.
A circle's circumference is 43.96 cm. what is the length of the circles diameter?
Answers
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

oranges for a cost of $2.15. Find the cost of one apple.
Answers
Apples = x
Oranges = y
3x + 2y = 1.55
4x + 3y = 2.15
I like the substitution method
2y = -3x + 1.55
y = -1.5x + 0.775
4x + 3(-1.5x + 0.775) = 2.15
4x - 4.5x + 2.325 = 2.15
-0.5x + 2.325 = 2.15
-0.5x = -0.175
x = 0.35

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?
Answers
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
