Graph this point on the coordinate plane: (5, -21/2)
Answers
To answer this question, we have that the point is:
[tex](5,-2\frac{1}{2})[/tex]We can see that the value for x = 5, and the value for y is a mixed fraction, and this fraction is equivalent to:
[tex]-2\frac{1}{2}=-(2+\frac{1}{2})=-(\frac{4}{2}+\frac{1}{2})=-(\frac{5}{2})=-\frac{5}{2}=-2.5[/tex]Therefore, we can rewrite the coordinates as (5, -2.5).
Now, to graph this point, we need to find in the coordinate plane, x = 5, and y = -2.5 as follows:

The values of the variable are given as
a = -2.5
Also, we have the values of the another variable to be given as
b = 2/5
Substitute a = -2.5 and b = 2/5 in the expression a - b
So, we have
a - b = -2.5 - 2/5
Express the fraction as decimal

Identify the zeros and state their multiplicities describe the effect on the graph #7
Answers
Answer:
Explanation:
Here, we want to get the zeros, multiplicity, and effect of the zeros of the polynomial
To get this, we can set the function to zero and factorize it
Mathematically, we have that as:
[tex]x^2(x^2-2x-8)\text{ = 0}[/tex]We can further have the equation broken down as follows:
[tex]\begin{gathered} x^2((x+2)(x-4))=\text{ 0} \\ x^2=0 \\ x+2\text{ = 0} \\ x-4=0 \\ x\text{ = 0 twice, -2 , 4} \end{gathered}[/tex]Now, let us get the effect of these zeros on the graph
As we can see, only x = 0 has an even multiplicity (2), x = -2, and 4 have an odd multiplicity
When there is an even multiplicity, the zero will touch the the graph, but when there is an odd multiplicity, the graph will cut through the x-axis at that point
Thus, we can conclude that:
At x = 0, the curve or graph will touch the x-axis and bounce off
At x = -2, the graph will cut through the point x = -2
At x = 4 , the graph will cut through the point x = 4

How to factor Algebraic expressions?We are given the expression as; 36a - 16
Now, we want to write an equivalent expression of 36a - 16.
However, according to question, 36 and 16 are both divisible by 4. Thus, we will divide both sides by 4 to get;
36/4 = 9 and 16/4 = 4
Now, factorize the given expression 36a - 16.

Their value is $3.05 how many of each kind of coin are there?
Answers
Problem #1:
x = adults
y = children
x + y = 166
2.10x + 0.75y = 293.25
x = 166 - y
Now we substitute the x value on the second equation:
2.10(166 - y) + 0.75y = 293.25
And we solve for y:
y = 41.
Now we substitute the y value on the first equation:
x = 166 - 41
x = 125
There are 125 adults and 41 children
As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 50 milligrams of Medication A with 40 milligrams of Medication B. However this week, the doctor said to only use 16 milligrams of Medication B. How many milligrams of Medication A should be mixed this week? Answer: milligrams Question Help: D Video Read Submit Question
Answers
If by last week, your patient's doctor indicated that you should mix 50 milligrams of Medication A with 40 milligrams of Medication B, then;
A:B = 50:40
Using equality postulate, we can say;
50mg of A = 40mg of B
however if this week, the doctor said to only use 16 milligrams of Medication B, in order for us to get the amount of equivalent milligram for medication A, we will also usse the equality postulate say:
x mg of A = 16mg of B (I had to use x since we do not know the dosage of medication A)
Solving both expression to get x:
50mg of A = 40mg of B
x mg of A = 16mg of B
Simply cross multiply since both medications are always mixed in the same proportion:
40 * x = 50 * 16
40x = 800
Divide both sides by 40
40x/40 = 800/40
x = 20
Therefore 20miligram of medication A should be mixed this week

How do you know a relationship in Linear? Describe how you know based on thegraph, based on the table and based on if you have an equation.
Answers
The linear relationship must follow the general rule:
[tex]y=m\cdot x+b[/tex]where m is the slope of the linear relationship and b is called the y-intercept
if b = 0, so, it will be a proportional relationship
So, if we have a graph, the graph will be a line
The slope of the line will be = rise/run
Where rise = the difference between y-coordinates
And the run will be = the difference between x-coordinates
If we have a table, we will find the slope using two points from the table with the ordered pair (x1, y1) and ( x2, y2 ) as follows:
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]The ratio must be constant between any two points from the table
Finally, if we have an equation, it must be like the general form or can be converted to the general form
In general, the linear equation has a degree of 1
