Answer:
given, y≥2x+1 and
y>21x−1
first, draw the graph for equations y=2x+1 and y=21x−1
for y=2x+1
substitute y=0 we get, 2x+1=0⟹x=−0.5
substitute x=0 we get, y=1
therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.
Hence, y≥2x+1 includes the region above the line.
for y=21x−1

Answer:
C. [tex]\sqrt{89}[/tex] cm
Step-by-step explanation:
First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :
a^2 + b^2 = c^2
a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.
8^2 + 5^2 = c^2
64 + 25 = c^2
89 = c^2
To get c alone, we do the square root of 89.
[tex]\sqrt{89}[/tex] = c
9.43398113 = c
So, the answer is C. [tex]\sqrt{89}[/tex] cm

Luke went shopping for a new pair of pants. The listed price of the pair of pants was $21, but the price with tax came to $22.05. Find the percent sales tax.
Answer:
5%
Step-by-step explanation:
22.05-21=1.05
1.05/21=.05
.05*100=5%
The sales tax is 5% of listed price.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, Luke went shopping for a new pair of pants.
The listed price of the pair of pants was $21.
But the price with tax came to $22.05.
The taxed amount
= $22.05 - $21
= $1.05
To find the percentage of taxed amount:
We use the percentage formula,
let m be the required percentage.
So,
1.05 = m x 21 /100
m = 1.05 x 100 / 21
m = 105 /21
m = 5%
Therefore, taxed amount is 5% of original price.

In the figure below, AB=AC=50, AD=52, and BC=28. Determine CD.
Check the picture below, on the left side.
since the triangle ABC is an isosceles with twin sides, if we drop a line bisecting the angle at the vertex A, we end up with a perpendicular line that cuts the "base" in two equal halves, so then
[tex]\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=\stackrel{hypotenuse}{50}\\ a=\stackrel{adjacent}{14}\\ b=opposite\\ \end{cases} \\\\\\ \sqrt{50^2 - 14^2}\implies \sqrt{2500 - 196}=b\implies \sqrt{2304}=b\implies 48=b[/tex]

What is a function?An expression which defines the relationship between two variables (one independent and one dependent variable).
What is dependent and independent variable?The independent variable is the variable being controlled in the problem, and the dependent variable is the variable that changes with the change of independent variable.
What is decreasing linear function?If the slope of the function is negative, that means the output value decreases as the input value increases is called a decreasing linear function.
How to find out which x-values would have the greatest corresponding y-value ?Since the function is decreasing,
The y-value will decarese with the increase in value of x.So, for the minimum value of x, there will be maximum value of y.
So, for the greatest value of y, the value of x will be -2 which is minimum of all the options.

How many students are less than 69 inches in height
19
22
25
17
The number of students whose height less than 69" = 19
Hence option first is correct,
According to the given tally chart,
We can see that,
Frequency for height 65" = 1
Frequency for height 66" = 1
Frequency for height 67" = 9
Frequency for height 68" = 8
Since we have to calculate the number of students having height less than 69"
Therefore, neglect the other frequencies.
Now sum up the above frequencies,
= 1 + 1 + 9 + 8
= 19
Hence,
There are 19 students having height less than 69".
