What is a Function ?A function is defined as the law that build relation between a dependent variable and an independent variable.
It is given that
functions g and h are defined for all real numbers x as follows.
g(x) = 5x
h(x) = 4x-3
the expressions for (h+g)(x)= ?
(h+g)(x)= 5x+4x-3
(h+g)(x)= 9x-3
and (h-g)(x) = ?
(h-g)(x) = 5x - 4x +3
(h-g)(x) = x+3
and evaluate (h-g) (4).
(h-g)(x) = x+3
at x = 4
(h-g)(4) = 4+3 = 7
Therefore the value for the functions have been determined.

What is a Straight Line Function ?A straight line function is what can be written in the form of
y =mx +c
where m is the slope and c is the intercept on y axis.
The intercept on the y axis , c = 1
at x = 4 , y=0
and at x = 0, y =1
The slope can be calculated as
y = mx+1

Here is the graph of a quadratic function f.
Answer:
B) x² - 8x + 12
E) (x -4)² - 4
F) (x - 2)(x - 6)
Explanation:
As the graph opens upwards. The value of x² will be positive.
The x intercepts are (2, 0), (6, 0) determining (x -2)(x-6)
The (x - 4)² - 4 determines the vertex of x = 4, y = -4
When simplified:
⇒ (x -2)(x-6)
⇒ x² - 2x -6x + 12
⇒ x² - 8x + 12
There are 1,486 souvenir paperweights that need to be packed in boxes. Each box will hold 16 paperweights. How many boxes will be needed?
Answer: 93 boxes will be needed
Step-by-step explanation:
If each box holds 16 paperweights, and 1,486 need to be packaged, we will divide 1,486 by 16.
1,486 / 16 = 92.875
We will assume you cannot have 0.875 of a box, so we will round up to:
93 boxes will be needed

An item costs $490 before tax, and the sales tax is $44.10.
Answer:
The item has a 9% sales tax.
Step-by-step explanation:
Given the following question:
We are given an item that costs 490 dollars before tax, the sales tax of the item is $44.10, which means the item will cost $534.10 in total. Assuming what you are asking is to find the percentage of the sales tax we will use the formula to calculate percentages, and then add that answer to our before cost to confirm our answer.
Formula to calculate percentages:
[tex]\frac{p\times n}{100}[/tex]
[tex]p=9[/tex]
[tex]\frac{9\times490}{100}[/tex]
[tex]9\times490=4410[/tex]
[tex]4410\div100=44.1=44.10[/tex]
[tex]490+44.10=534.10[/tex]
[tex]=534.10[/tex]
Our sales tax percentage is 9%.

[tex]A(t) = A(0)(1 \pm r)^t[/tex]
In which:
A(0) is the initial value.r is the rate of change, as a decimal.For the first restaurant, we have that the parameters are given as follows:
A(0) = 3000, r = -0.015.
Hence the profit after x weeks is given by:
[tex]y_1(x) = 3000(0.985)^x[/tex]
For the second restaurant, we have that:

The midpoint of a line segment has coordinates that are the average of the end point coordinates.
__
M = (A +B)/2 . . . . . . midpoint of segment between A(1, 4) and B(1, -5)
M = ((1, 4) +(1, -5))/2 = (1 +1, 4 -5)/2 = (2, -1)/2
M = (1, -1/2)
The midpoint of the vertical line segment is (1, -1/2).

Additional comment
The midpoint will always be on the line segment. Since this line segment is vertical with x = 1, the x-coordinate of the midpoint must be 1.

An elevator can hold a maximum of 1500 pounds. An average child weighs 75 pounds and the average adult weighs 150 pounds. The elevator also can’t fit more than 14 people. How many children and adults can fit in the elevator and stay under the weight limit. Write the inequalities that represent the word problem, and then graph it on DESMOS. What is a solution that represents the amount of children and adults and their combined weight?
Let's take this problem step-by-step:
Let's first set up some variables:
c: # of childrena: # of adultsLet's examine the information given:
Elevator can hold a maximum of 1500 pounds⇒ average child is 75 pounds
⇒ average adult is 150 pounds
⇒ therefore: [tex]75c + 150a\leq 1500[/tex]
Elevator can fit no more than 14 people⇒ therefore: [tex]c + a \leq 14[/tex]
Let's graph the equations:
[tex]75c+150a\leq 1500\\c+a\leq 14[/tex]
⇒ look at the image attached
The point at which the two graphs intersect:
⇒ is the solution that represents the amount of children and adults and
their combine weight
With the horizontal axis being the # of children and vertical axis being the # of adults:
⇒ the solution is 8 children and 6 adults
Answer: 8 children and 6 adults
