Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y is less than negative 3 over 4 times x minus 1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically

Answer:
A) The graph is the quadrant of the coordinate plane that lies between the two lines and to the left of the point (-2 14/15, 1 1/5)
B) no; it does not satisfy either inequality
Step-by-step explanation:
A) The boundary line defined by the first inequality is a dashed line with a slope of 3 and a y-intercept of 10. Shading is above the line (and to its left).
The boundary line defined by the second inequality is a dashed line with a slope of -3/4 and a y-intercept of -1. Shading is below the line (and to its left).
The two lines cross at the 2nd-quadrant point (-2 14/15, 1 1/5). The solution area is the area between the crossing lines and to the left of that point. Neither that point nor any point on either line is part of the solution area.
The solution area is the doubly-shaded area in the attached graph.
__
B) The first-quadrant point (8, 10) is not in the solution area, since the solution area is comprised of parts of quadrants 2 and 3 only.
We can see that (8, 10) will not satisfy either inequality:
10 > 3(8) +10 . . . . not true
10 < -3/4(8) -1 . . . . not true
Complete the reasons for the proof.

Answer:
521 mm²
Step-by-step explanation:
Hi there !
A = Asemicircle + Atrapeze
Asemicercle formular = d/2 = 20mm/2 = 10mm
Asc = π·r²/2
= 3.14·(10mm)²/2
= 3.14×100mm²/2
= 157 mm²
Atrapeze formulaAt = (b + B)×h/2
= (20mm + 32mm)×14mm/2
= 52mm×7mm
= 364 mm²
A = Asc + At= 157mm² + 364mm²
= 521 mm²

Answer:
Greatest = 98,321
Least= 12,389
98,321>12,389
Step-by-step explanation:
there are only 5 digits. To get the greatest number, the digits with the most value should be put in front to ensure the great value.
To get the smallest number, the digits with the least value should be put in front.
The greater valued number is greater than the least valued number

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
Can you help me find the surface area of this prism?
Answer:
To find the surface area of this parallelepiped, we need to know how to find the area of a regular parallelogram.
Formula for area of a parallelogram;
A = BH
Where b represents the base, and h displays as the height.
Once, we know how to find the area of a parallelogram, we find the areas of the three different sides of this figure and multiply it by two since opposite sides have an equal area.
Now we find the area of the front parallelogram:
A = BH
Plug in our values;
A = 4(2)
A = 8, and since opposite sides are equal:-
8(2) = 16, is the area of both the front and back parallelograms.
Now the top and bottom bases of this parallelepiped.
But, to find the height and base of this, we transfer the base of the front parallelogram and the base of the right parallelogram. So our base and height is 4.
A = BH
Plug in our values;
A = 4(4)
A = 16, and since opposite sides are equal:-
16(2) = 256, is the area for both the upper and bottom bases.
Now for the right and left parallelograms;
A = BH
Plug in our values;
A = 4(2.5)
A = 10, since opposite sides are equal:-
10(2) = 20, is the area of both the right and left parallelograms.
Now we add all the areas together:
16 + 256 + 20
= 292 square meters.

Use vector operations to draw the resultant vector
Draw 2u – 1/3v.
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
[tex]y_1 = 2u[/tex]
[tex]y_2 = -\frac13v[/tex]
See attachment for the graphs of y1 and y2.
Next, we have:
[tex]y = 2u - \frac13v[/tex]
So, we have:
[tex]y = y_1 + y_2[/tex]
The above expression means that, we add the vectors y1 and y2 to get vector y

Step-by-step explanation:
Find the percent change. State whether it is an increase or decrease. Round to the nearest tenth of a percent. From 27 to 31
Given parameters:
Initial value = 27
Final value = 31
Unknown:
Percentage change = ?
Solution:
The percentage change is the difference between the final and initial value divide by the initial value multiplied by 100;
Percentage change = [tex]\frac{Final value - Initial value}{Initial value} x 100[/tex]
Input the parameters and solve;
Percentage change = [tex]\frac{31 - 27}{27} x 100[/tex]
= 14.8%
The percentage change is 14.8%. This is an increase because the value move from 27 to 31.
A penguin walks 10 feet in 6 seconds. how far does the penguin walk in 45 seconds EXPLAIN OR SHOW YOUR REASONING
Answer:
75 feet in 45 seconds
Step-by-step explanation:
*disclaimer*
dont know if this is how you were taught to do this but heres how i was:
[tex]6 sec /10 ft. = 45 sec / x[/tex]
Set this up as a proportion.
Then multiply 10 ft by 45 sec, and 6 sec by x
Your equation then simplifies to
6x = 450
x = 75
Based on the table, what is the number string that corresponds to the text “Hello Raya”?
The number string is an illustration of the addition operation
The number string that corresponds to the text “Hello Raya” is 97
How to determine the number string?The text is given as:
“Hello Raya”
From the table in the complete question, we have the following representations:
H = 8; E = 5; L = 12; O = 15; R = 18; A = 1; Y = 25; _ or space = 0
The sum of the numerical values of the characters are:
Sum = 8 + 5+ 12 + 12 + 15 +0 + 18 + 1+ 25 + 1
Evaluate the sum
Sum = 97
Hence, the number string that corresponds to the text “Hello Raya” is 97
