Answer:
Expressions A, C, D are equivalent
Step-by-step explanation:
Equivalent expressions:
Two expressions are equivalent if they give the same result. So
Option A:
3(2 + 4x) =3*2 + 3*4x = 6 + 12x
So equivalent
Option B:
3(2 + 6x) + 2x = 3*2 + 3*6x + 2x = 6 + 18x + 2x = 6x + 20. So not equivalent
Option C:
5(1+2x) + 1 + 2x = 5*1 + 5*2x + 1 + 2x = 5 + 10x + 1 + 2x = 6 + 12x.
Equal, so equivalent
Option D:
7*(1+2x) - 2x - 1 = 7*1 + 7*2x - 2x - 1 = 7 + 14x - 2x - 1 = 6 + 12x
Equal, so equivalent.
Option E:
7*(1+2x) + 2x - 1 = 7*1 + 7*2x - 2x - 1 = 7 + 14x + 2x - 1 = 6 + 16x
Different, so not equivalent.

Answer:
overestimate = 7
underestimate = 5
Step-by-step explanation:
Table
_________________________________
Time (months) 0 1 2 3 4 5 6
Rate 5 7 9 14 22 31 40

A. Make an overestimate and an underestimate of the total quantity of pollutants that escape during the first month.
Overestimate
For this case, we review the data in the table. The value for first month of total quantity of pollutants that escape is 7. Additionally, we can notice that the rate is increasing.
Just a month and that month has a value of 7
= 1* 7 (The largest value) = 7
Underestimate
This would be equivalent to the total until the previous meassure

Answers
Answer:
the number of possible selection is 12650
Option b) 12650 is the correct answer.
Step-by-step explanation:
Given the data in the question;
total number of students n = 25
number of student selected r = 4
[tex]^nC_r[/tex] = ²⁵C₄
= 25! / ( 4!( 25 - 4 )! )
= 25! / (4!(21)!)
= 12650
Therefore, the number of possible selection is 12650
Option b) 12650 is the correct answer.

The slope of the line represented by the equation y= -2/3 - 5x is -5.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have,
y= -2/3 - 5x
We know from slope intercept form
y= mx + b
Where m is the slope and b is the y intercept.
Now, Comparing with given equation we get
m = -5 and b= -2/3
Thus, the slope of line is -5.

Mr. Nelson sold a car for $1,380 that cost
him $1,500. What was his percent of loss
based on the cost?
Answers
Answer:
The loss is $120 and the loss percentage is 8%.
Step-by-step explanation:
Given that,
SP of a car = $1,380
CP of a car = $1,500
As CP > SP, it means there is a loss in selling of that car.
Loss = CP - SP
= $1,500 - $1,380
= $120
Loss percentage,
[tex]\%=\dfrac{loss}{CP}\times 100\\\\=\dfrac{120}{1500}\times 100\\\\=8\%[/tex]
Hence, the loss is $120 and the loss percentage is 8%.

Write an equation to represent the relationship between red paint, r, and yellow paint, y, in each batch.
Answers
The equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given:
At r = 2, y = 3,
r = 4, y = 6,
r = 6, y = 9
Here, r is red paint and y is yellow paint.
The above condition can be written as
2r = 3y
r = 3 / 2y
Therefore, the equation to represent the relationship between red paint, r, and yellow paint, y, in each batch can be written as r = 3 / 2y.
