Using the distributive property, it is found that the equivalent expression is:
18c - 30d + 36
What is the distributive property?It is a property that the outside term multiplies each of the inside terms.
In this problem, the expression is:
6(3c - 5d + 6).
Hence, we apply the property, with the outside term 6 multiplying each of the inside terms, hence the equivalent expression is given by:
6(3c - 5d + 6) = 18c - 30d + 36.

Answer:
a. y = 10
b. x = 5 - (5y/2)
c. y = 6x - 11
Step-by-step explanation:
a.
2(y - 3) = 4
2y - 6 = 4
2y = 10
y = 5
b.
2x + 5y = 10
2x = 10 - 5y
x = 5 - (5y/2)
c.
6x + 3y = 4y + 11
6x = y + 11
y = 6x - 11

Under a dilation, are the pre-image and the image always,
sometimes, or never congruent?
Answer:
Never congruent
Step-by-step explanation:
A dilation is a transformation that makes an image that is thr same shape as the original, but a DIFFERENT SIZE.
Congruent shapes means they both have the same shape AND size.
So a dilation of the new image/shape can NEVER have the same shape AND size with the original.

If I were to be walking 8MPH How fast would I be walking per minute? PLEASE HELP. (Hint: Half of 8MPH is 4, so that would be 4 Miles every 30 minutes.)
Answer:
0.13 miles per minute
Step-by-step explanation:
If you walk 8 miles in an hour, that is 8 miles per 60 minutes. We can divide 8 by 60 to get the miles per minute because there are 60 minutes in an hour. 8/60 = 0.13 (3 is repeating)
There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?
Answer:
16/81
Step-by-step explanation:
Given
In the bag, there are : 4 blue and 5 red marblesProbability of blue (1st time)
P(1) = Total blue / Total marblesP(1) = 4 / (4 + 5)P(1) = 4/9Probability of blue (2nd time)
P(2) = Total blue / Total MarblesIt states it is replaced hence it is of the same constitution as the beginningP(2) = 4/9Probability of blue (both times)
P = P(1) x P(2)P = 4/9 x 4/9P = 16/81All digits in a dropdown number are different and one of its digits is the average of all its digits. It has at least two digits. For example, 5021 is a dropdown number, but neither 4389 nor 6033 is a dropdown number. a Find the smallest dropdown number.

Answer: (x - 2)^2 + (y + 3)^2 = 18 3(2^(1/2)) (2,-3)
Step-by-step explanation:
7x^2 - 28x + 7y^2 + 42y - 35 = 0
divide 7 out
x^2 - 4x + y^2 + 6y - 5 = 0
add 5 to other side
x^2 - 4x + y^2 + 6y = 5
solve by completing the square
take b values divide them by 2 square and add to both sides
-4/2 = -2
-2^2 = 4
6/2 = 3
3^2 = 9
X^2 - 4x + 4 + y^2 + 6y +9 = 4 + 9 +5
(x - 2)^2 + (y + 3)^2 = 18

To determine the range of the data, we need to subtract the biggest value of the data (8) from the smallest value of the data (1).
⇒ Range of a data: Biggest number - Smallest number⇒ Range of a data: 8 - 1⇒ Range of a data: 7Thus, 7 is the range.
2. Determining the mode of the line plot:
The mode of the data is the digit that has repeated the most. In this case, the digit "2" has repeated five times and has repeated the most.

The width of a rectangle with area 55in^2 depends on its length. write the formula that describes the width of the rectangle as a function of its length.
(screenshot attached if you need to see the problem better)
The formula that describes the width of the rectangle as a function of length is w = 55 / m.
How to find area of a rectangle?area of a rectangle = lw
where
l = lengthw = widthTherefore,
area = 55 inches²
length = m
width = w
Hence,
area = mw
55 = mw
divide both sides by m
55 / m = wm / m
w = 55 / m

Solution:Let's solve the given problem step by step :
[tex]:\implies \quad \sf - 3(x + 5) = - 9[/tex]
First, distribute the given problem :
[tex]:\implies \quad \sf - 3(x + 5) = - 9[/tex]
[tex] \sf:\implies \quad - (3 \times x) - (3 \times 5) = - 9[/tex]
Add 15 to both sides :

[tex] \sf:\implies \quad - 3x - 15 + 15 = - 9 + 15[/tex]
On simplifying :
[tex] \sf:\implies \quad -3x-15+15 = -9+15[/tex]
[tex] \sf:\implies \quad - 3x = 6[/tex]
Dividing both sides with same factor :

What is the recursive rule?
Question 2 options:
an = an+1 + 500; a1 = 30,000
an = an−1 + 30,000; a1 = 500
an = an−1 + 500; a1 = 29,500
an = an−1 + 500; a1 = 30,000
Mr. Red's salary is an illustration of an arithmetic sequence
The recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000
How to determine the recursive formula?From the complete question, we have the explicit rule of Mr. Red's salary to be
an = 500n + 29500
Where:
First term, a1 = 30000Common difference, d = 500The above means that:
The difference between a term and the next term is 500.
So, the recursive rule is:
an = an−1 + 500
Recall that:
a1 = 30000
Hence, the recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000
