According to the 2010 census, the population of Nebraska was 1.8 × 106 people. Which state had a smaller population?
(1 point)
California: 3.7 × 107
Rhode Island: 1.1 × 106
Texas: 2.5 × 107
Missouri: 6 × 106
Rhode Island has a smaller population.
Here,
According to the 2010 census, the population of Nebraska was 1.8 × 106 people.
We have to find the smaller population.
What is Product?
The multiply of two or more number is called Product.
Now,
The population of Nebraska was 1.8 × 106 people.
1.8 x 106 = 190.8
And,
The population of California = 3.7 x 107 = 395.9
The population of Rhode Island = 1.1 x 106 = 116.6
The population of Texas = 2.5 x 107 = 267.5
The population of Missouri = 6 x 106 = 636
Hence, Rhode Island has a smaller population.

Answer: a. (0, -300), (1, -180), (2, -60), (7, 540)
b. T=120D-300
c. $28080
Step-by-step explanation:
a. T=120D-300 ==> per week
D=0: T=120(0)-300
D=0: T=-300 ==> (0, -300)
D=1: T=120(1)-300

How to find the counterexample?Here we have the statement:
"The sum of two numbers is always greater than their difference"
So we just need to find two numbers such that the statement is false.
This is really trivial, for example, we can propose the numbers 0 and 0.
The sum gives 0 + 0 = 0
The difference is 0 - 0 = 0
The sum is not greater than the difference.
Now, I will propose a less trivial counterexample, let's use the numbers 1 and -1.
The sum gives 1 + (-1) = 1 - 1 = 0
The difference gives: 1 - (-1) = 1 + 1 = 2

The distributive property also combines subtraction and multiplication for example, 3 x (5 — 2) = (3 x 5) —(3 x 2). Explain how you could use the Distributive Property and mental math to find 5 x 198.
After using distributive property we find the solution of 5 × 198 is 990.
What is Distributive property?
By the rule of distributive property, multiplying the sum of two or more addends by a number gives the same result as when each addend is multiplied individually by the number and the products are added together.
The expression is given as;
5 × 198
Now, By using distributive property we calculate as;
5 × 198 = 5 × ( 200 - 2 )
= (5 × 200) - (5 × 2)
= 1000 - 10
= 990
Hence, After using distributive property we find the solution of 5 × 198 is 990.

the system of inequalities that represents the possible length in meters, l, and the possible width in meters, w, of the pool is given as w ≤ l - 10 and 2 l + 2 w > 62.
Let the length of the pool be x.

x - 10 ≥ width
w ≤ x - 10
w ≤ l - 10
Also, it is given that, the perimeter of the pool is more than 62 m

For the given systems of equations, we have that:

2) There is one solution: (1.58, -3.45, 3.89).
3) There is one solution: (3, 2, 4).
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For item 1, the system is:
3x + y - z = -5.-4x + 2y + z = 17.-2x - 4y + z = -7.From the first equation, we have that:
z = 3x + y + 5.
Replacing on the second equation, we have that:
-4x + 2y + 3x + y + 5 = 17
-x + 3y = 12
x = 3y - 12.
Replacing on the third equation, we have that:
-2x - 4y + 3x + y + 5 = -7
x - 3y = -12
Since x = 3y - 12:
3y - 12 - 3y = -12
0 = 0.
Free variable, hence:
x = 3y - 12.y = y.z = 3x + y + 5 = 9y - 36 + y + 5 = 10y - 31.The infinite solutions have the following format: (3y - 12, y, 10y - 31).
For item 2, the system is:
x + 5y + 3z = -4.x + 2y - 3z = 8.-3x + 2y + 3z = -12.From the first equation:
x = -4 - 5y - 3z.
Replacing on the second equation:
-4 - 5y - 3z + 2y - 3z = 9.
-3y -6z = 13.
3y + 6z = 13.
Replacing on the third equation:
-3(-4 - 5y - 3z) + 2y + 3z = -12
12 + 15y + 9z + 2y + 3z = -12
17y + 12z = -14.
From the second equation, we have that:
z = (13 - 3y)/6.
Hence, replacing on the third again:
17y + 2(12 - 3y) = -14
11y + 24 = -14.
y = -3.45.
z = (13 - 3 x (-3.45))/6 = 3.89.
x = -4 - 5(-3.45) - 3(3.89) = 1.58.
Hence:
There is one solution: (1.58, -3.45, 3.89).
For item 3, the system is:
-4x - 2y + 5z = 4.5x + 2y - z = 15.5x - 2y - 3z = -1.From the second equation:
z = 5x + 2y - 15.
Replacing on the first:
-4x - 2y + 5(5x + 2y - 15) = 4
-4x - 2y + 25x + 10y - 75 = 4
21x + 8y = 79.
Replacing on the third:
5x - 2y - 3(5x + 2y - 15) = -1
5x - 2y - 15x - 6y + 45 = -1.
-10x - 8y = -46.
Adding both resulting equations, we have that:
11x = 33.
x = 3.
Then
21x + 8y = 79.
63 + 8y = 79
8y = 16
y = 2.
z = 5x + 2y - 15 = 5(3) + 2(2) - 15 = 4.

Rewrite the following standard form linear equation into slope-intercept form. Write the answer starting with y=
12x-4y=-12
The equation of the line in the slope-intercept form is given y= 3x + 3 .
The graph of the equation y = mx + c is a line with m as the slope and m and c as the y-intercept. In the slope-intercept representation of the linear equation, the values of m and c are real numbers. A line's slope, expressed in m, indicates how steep it is. A line's gradient is also referred to as its slope occasionally. The y-coordinate of the point where the line's graph meets the y-axis is known as the y-intercept, or c, of a line.
The equation of the line is given by 12x - 4y = -12 .
This is the standard form of the line.
Now to represent the line in the slope-intercept form we need to write the equation for y in terms of x.
or, 12x-4y=-12
or, -4y = -12x - 12
or, y = (-12x - 12 ) ÷ (-4)
or, y = 3x + 3
Here the slope is 3 and the y-intercept is also 3.
Therefore the slope-intercept form of the line is given by y = 3x + 3

What is an equation of the line that passes through the points (−1,−7) and (−8,0)?
The equation of the line that passes through the points is y = -x - 8
What is an equation of the line that passes through the points?The points are given as:
(−1,−7) and (−8,0)
Calculate the slope (m) using
m = (y2 - y1)/(x2 - x1)
So, we have
m = (0 + 7)/(-8 + 1)
This gives
m = -1
The equation of the line that passes through the points is then calculated as
y = m(x - x1) + y1
So, we have
y = -1(x + 8) + 0
This gives
y = -x - 8
Hence, the equation of the line that passes through the points is y = -x - 8

23p – 101 = 65p – 40 – p
2.3p – 14.1 = 6.4p – 4
The equivalent equation for the given equation is 2.3p - 10.1 =6.49p - 4. Therefore, option B is the correct answer.
Given that, 2.3p – 10.1 = 6.5p – 4 – 0.01p.
We need to find which equations have the same solution as the given equation.
What is an equivalent equation?Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
Now, 2.3p - 10.1 = 6.5p - 4 - 0.01p can be simplified as follows:
To add or subtract terms of algebraic equations group like terms add numerals and keep the variables the same.
That is, 2.3p - 10.1 = (6.5p - 0.01p) - 4

The regions is represented as :
A = p - p ∩ q , B = p ∩ q and C = q - p ∩ q
According to the question we have been given the Venn diagram with two regions p and q.
We need to find the representation of regions A, B and C.
As we can from the diagram,
region A is the area where the only p statement is there which exclude the B region . That is A is area of difference.
So it can be represented as
A = p - p ∩ q
region B is the intersection of p and q.
So it can be represented by
B = p ∩ q
region C is the area where only q statement is there and excludes the intersection region. That is C is area of difference
So it can be represented as
C = q - p ∩ q
Hence the regions is represented as
A = p - p ∩ q
