Suppose that the functions p and q are defined as follows.

Find the following.

What is function?
A function from A to B is a rule that maps to each element of A a unique element of B.
A is called the domain of the function and B is called the co domain of the function.
We can do addition, subtraction, multiplication, division and composition on functions.
Let f and g be two functions
f[tex]o[/tex]g(x) = f(g(x)) and g[tex]o[/tex]f(x) = g(f(x))
This is known as composition of function.
Here,
[tex]p(x) = x^2 + 6\\q(x) = \sqrt{x} +1[/tex]
q[tex]o[/tex]p(x) = q(p(x))
=[tex]q(x^2+6)[/tex]
= [tex]\sqrt{x^2+6}+1[/tex]
q[tex]o[/tex]p(3) = [tex]\sqrt{3^2+6}+1[/tex]
= [tex]\sqrt{15}+1[/tex]
p[tex]o[/tex]q(x) = p(q(x))
= p([tex]\sqrt{x}+1[/tex])
= [tex](\sqrt{x}+1)^2+6[/tex]
= [tex]x + 1 + 2\sqrt{x} + 6[/tex]
= [tex]x + 2\sqrt{x} +7[/tex]

Using the given parameters in the question, we have the following system of equations
2a + 8b + 8c = 1400 --- (1)
4a + 7b + 10c = 1660--- (2)
3a + 9b + 9c = 1650 --- (3)
Subtract equation (2) from twice equation (1)
So, we have
(4a + 16b + 16c = 2,800) - (4a + 7b + 10c = 1,660)
This gives
9b + 6c = 1140 --- (4)
Subtract four times equation (3) from three times equation (2)
So, we have
12a+ 21b +30c = 4,980 -(12a + 36B + 36c = 6,600)
This gives
-15b - 6c = -1,620 --- (5)
Add equations (4) and (5)
(9b + 6c = 1140) + (-15b - 6c = -1620)
So, we have
-6B = -480
Divide by -6
b = 80
Substitute b = 80 in -15b - 6c = -1,620
-15 x 80 - 6c = -1,620
Evaluate
-1200 - 6c = -1,620
So, we have
-6c = -420
Divide
c = 70
In (2), we have
4a + 7b + 10c = 1660
This gives
4a + 7 * 80 + 10 * 70 = 1660
Evaluate
4a = 400
Divide
a = 100
On Thursday, we have
a = 4, b = 6 and c = 3
So, we have
Total = 4 * 100 + 6*80 + 3*70
Evaluate
Total = 1090
Hence, the total earnings is 1090

Answer:
D. In the ordered pair (9,7), 7 is the x-coordinate
Explanation:
The ordered pairs have the form (x, y) where the first number is the x-coordinate and the second number is the y-coordinate. So, in the ordered pair (9, 7), 7 is the y-coordinate. This makes the last statement false and the answer is
D. In the ordered pair (9,7), 7 is the x-coordinate.

(a) slope:

,
point:
(1, 5)
The linear equation can be written as:
y = (3/4)*x + 17/4
And the graph can be seen at the end.
How to graph the linear equation?
A general linear equation is of the form:
y = m*x + b
Where m is the slope and b is the y-intercept.
Here we have the slope m = 3/4, so we get:
y = (3/4)*x + b
And the line passes through (1, 5), replacing these values in the equation we get:
5 = (3/4)*1 + b
5 - 3/4 = b
20/4 - 3/4 = b
17/4 = b
So the linear equation is:
y = (3/4)*x + 17/4
To graph the line we need other point, if we use x = 0 we get:
y = (3/4)*0 + 17/4 = 17/4
Then we have the points (1, 5) and (0, 17/4).
To graph the line, we just need to find these two points and connect them with a line, the graph can be seen below.

What is the actual distance between these two cities in kilometers?
1) Whenever we have problems that deal with the real distance and distance on the map, we can write out the following formula:

Sarah got a $60 gift card to Walmart. She uses the gift card to buy orange juice for $4.50. She also wants to use the gift card to buy shirts. Each shirt costs $2.29. Write an inequality to describe this situation, where n is the number of shirts Sarah wants to buy?Please answer quick, will give 18 points
ANSWER
[tex]4.50+2.29n\le60[/tex]EXPLANATION
We have that Sarah got a $60 gift card to use in Walmart.
This means that everything she can buy cannot be worth more than $60 (i.e. less than or equal to $60).
She buys orange juice for $4.50 and she wants to buy shirts (which cost $2.29 each)
Let n be the number of shirts Sarah wants to buy.
This means that the cost of n shirts is $2.29n.
Recall that she can only spend less than or equal to $60. This means that the sum of the cost of the orange juice and n shirts is less than or equal to $60.
That is:
[tex]4.50+2.29n\le60[/tex]That is the inequality that represents the situation.
What do we call the total area of all exposed surfaces of a geometric solid?
The total area of all exposed surfaces of a geometric solid is called surface area .
What does it mean by surface area of geometric solid ?The area is the entire amount of space filled by flat or two-dimensional objects. In other words, the number of square units that cover the surface of a closed figure is used to represent its area.
It is quantified in square inches, or square units. The area only has length and width since 2-dimensional shapes can be measured using them.
The area is a two-dimensional measurement of the size of a flat surface, whereas surface area is a measurement of a solid shape's exposed surface (three-dimensional).
The main distinction between area and surface area is this. However, both amounts are expressed in square units, which is the same for both. Learn the distinction between area and volume as well.
