Answer:
[tex](a)\ u \le -4[/tex]
[tex](b)\ u =\{-\infty,.....,-6,-5,-4\}[/tex]
Step-by-step explanation:
Given
[tex]-u \ge 4[/tex]
Solving (a): An equivalent inequality
We have:
[tex]-u \ge 4[/tex]
Multiply both sides by -1 (this changes the inequality)
[tex]-u*-1 \le 4 * -1[/tex]
[tex]u \le -4[/tex]
Solving (b): Values of u from least to greatest
[tex]u \le -4[/tex] implies that u ends at -4, starting from negative infinity
So, the list is:
[tex]u =\{-\infty,.....,-6,-5,-4\}[/tex]

The area of a rectangle is 20 square units and its length is 5 centimeters. Find its perimeter
Answer:
18 centimeters.
Step-by-step explanation:
Since you already know the length (height) divide 20 by 5 = 4.
This gives you the width (4), add up all the sides ( 4 + 4 + 5 + 5).
The sum comes out to be 18.
The areaot a square is 36 cm? What
is the side length, s?
Answer: 6
Step-by-step explanation: To find the side length of a square, you need to find the square root of the area because the side length squared is the area.
What does x=_________
Answer:
x = 130˚
Step-by-step explanation:
x + 100˚ = 360˚
2 x = 360˚ - 100˚
2 x = 260˚
260˚ ÷ 2 = 130˚
If you roll the die 60 times, how many twos can you expect to roll?
Answer:
10
Step-by-step explanation:
Rolling a single six-sided die, you would get two 1/6th of the time because there is one two out of the six sides.
So 60 rolls would be 60*(1/6)=60/6=10

5. The owner of a bookstore developed a model for determining the price of rare comic books.
The price, P, of each book should vary directly with the number of people, N, that have
requested the book and inversely to the number of such books in existence, M. If N = 10 people,
M = 10,000 copies, and P = $5, then find P for N = 200 people and M = 100 copies.
Answer:
$\$ 10, 000 is the answer I think so
What is the relationship between circle A and circle B? part j
What is the missing angle measure?
Answer:
x = 33
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x
x = 180 - (90 + 57) = 180 - 147 = 33

(l) = 124
Find m
A. 20
B. 16
C. 17
D. 18
Answer: Choice C) 17 degrees
=============================================================
Work Shown:
Apply the law of cosines
c^2 = a^2 + b^2 - 2*a*b*cos(C)
12^2 = 28^2 + 18^2 - 2*28*18*cos(C)
144 = 1108 - 1008cos(C)
144+1008cos(C) = 1108
1008cos(C) = 1108-144
1008cos(C) = 964
cos(C) = 964/1008
C = arccos(964/1008)
C = 16.991286936969 which is approximate
C = 17 degrees
Note: arccos is the same as inverse cosine.

Help me if you can, "Margo practies her flute 1/4 hour a day.
Write and solve an equation to find how many hours Margo practices her flute in 1 week."
Answer:
Margo practices her flute playing 7/4 hrs/wk, or 105 minutes/week
Step-by-step explanation:
Multiply '1/4 hour per day" by '7 days.' We include this '7' because there are 7 days in one week.
1 hr 7 days
--------- * ------------- = 7/4 hours per week
4 day 1

A researcher started tracking the number of mice in the lab.
Which of the following equations models how many mice
there will be in the lab after 10 months?
Answer:
1536 rats will be total after 10 months
Step-by-step explanation:
The number is multiplied by 2 each time, so we have to continue multiplying by 2
Month 5: 48 x 2 = 96
Month 6: 96 x 2 = 192
Month 7: 192 x 2 = 384
Month 8: 384 x 2 = 768
Month 9: 768 x 2 = 1536
Month 10: 1536

X=
Help
Answer:
x = 13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = x^2
25+144 = x^2
169 = x^2
Taking the square root of each side
sqrt(169) = sqrt(x^2)
13 =x
Answer:
13
Step-by-step explanation:
[tex] \sqrt{5^{2} + 12^{2}} = \sqrt{169} \\ \\ \sqrt{169} = 13[/tex]

1. In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions
The measure of RS = 5 and ST = 4. What is the length of segment TU? Show each step.
(a)
rs x st = tu 2
(b)
yes it is possible the formula is in part a, but we're given just the side rt and st, not rs, but not to worry we can get rs with subtraction. we can do 9-4=5 for rs. now we can plug in our values to find tu
5x4 = tu 2
simplify with algebra
20 = tu
FINAL ANSWER
2 5 tu3x+9y=12
-3x-6y=18
Solve the system by using elimination
Answer: (x, y) = (-26, 10)
This means x = -26 and y = 10 pair up together
===============================================================
How to get that answer:
Add the equations straight down. Think of having 3 separate columns for the three different like terms.
3x + (-3x) becomes 0x and that's just 0. So the x terms go away9y + (-6y) is the same as 9y-6y which turns into 3y12 + 18 becomes 30After all that, we're left with the simpler equation 3y = 30. That solves to y = 10 after dividing both sides by 3.
Plug this back into any equation involving x and y. Solve for x
3x+9y = 12
3x+9(10) = 12
3x+90 = 12
3x = 12-90
3x = -78
x = -78/3
x = -26
We have found that x = -26 and y = 10 pair up together to form the solution.
-------------------
Checking the answer:
Plug (x,y) = (-26, 10) into the first equation
3x+9y = 12
3(-26)+9(10) = 12
-78+90 = 12
12 = 12
We get a true equation since the same thing is on both sides.
Repeat the same idea for the second equation
-3x-6y = 18
-3(-26) - 6(10) = 18
78 - 60 = 18
18 = 18
The second equation is true as well.
Both equations are true, so the solution (x, y) = (-26, 10) is confirmed.
Answer:
-26, 10
