To which set of numbers does the number –5 belong? Select all that apply. integers natural numbers rational numbers real numbers whole number.
Answer:
integers
rational numbers
real numbers
Step-by-step explanation:
i answered the question:)
Using number sets, it is found that the number -5 belongs to these following sets:
Integer numbers.Rational numbers.Real numbers.----------------------------------
Numbers are classified as:
Whole numbers: Set of numbers including all positive numbers and 0, so: {0,1,2,...}. This set is also called natural. Integer numbers: Number without decimals, that can be positive or negative, so: {...,-2,-1,0,1,2,....} Rational numbers: Integer plus decimals that can be represented by fractions, that is, they either have a pattern, or have a finite number of decimal digits, for example, 0, 2, 0,45(finite number of decimal digits), 0.3333(3 repeating is the pattern), 0.32344594459(4459 repeating is the pattern). Irrational numbers: Decimal numbers that are not represented by patterns, that is, for example, 0.1033430290339. Real numbers: Rational plus irrational.----------------------------------
-5 is a negative number, so it is integer.All integers are rational and real, and thus, -5 is integer, rational and real.A similar problem is given at https://brainly.com/question/10814303
is x^2 + y^2 = 5 a function
Answer:
No it is not a function.
Step-by-step explanation:
Answer:
No. This is NOT a function.
Step-by-step explanation:
Let D be the set of all students at GSU students, and let M(s) be 's is a math major," let C(s) be s is a computer science student," and let E(s) be "s is an engineering student." Express each statement using quantifiers, variables, and the predicates M(s), C(s), and E(s). a. No computer science students are engineering students. b. Some computer science students are also math majoers.
Answer:
Step-by-step explanation:
Recall the logic quantifiers [tex]\forall, \exists[/tex] which means for all/for every and exists.
a) This means that for every student in D that is a computer science this implies that the student is not an engineering student. So for a student s in D such that C(s) then E(s) is false. This is symboled by
[tex]\forall s \in D C(s) \implies \neg E(s)[/tex]
b) By saying "some computer science students" this means that there exists some studenst that study computer science and are also math majors. This is symboled by
[tex]\exists s \in D C(s)\land M(s) [/tex]
I NEED ANSWERS FAST. 1.Using the following image, find
FE given GF=6 and GE=13, 2.Using the following image, find
RS given ST=5and RT=11
.
Answer: FE is 7 and RS is 6.
Step-by-step explanation:
13 - 6 = 7
11-5= 6
Answer:
FE = 7
RS = 6
Step-by-step explanation:
for the first line, we know that line GE is 13 units long, and segment GF is 6 units. simply subtract 6 from 13 to get the length of segment FE.
13 - 6 = 7
You can do the same thing for the second problem.
11 - 5 = 6

A pump empties the pool at the rate of 1,000 gal every 4 hours. how long does it take to pump out 20,000 gallons?
Answer:
80 hours
Step-by-step explanation:
We can use ratios to solve
1000 gal 20000
-------------- = ------------------
4 hours x hours
Using cross products
1000x = 4*20000
1000x = 80000
Divide each side by 1000
x = 80000/1000
x = 80
80 hours

Step-by-step explanation:
50/x=10/20 and 10/50=20/x

Can anyone help me ?????
Answer:
Step-by-step explanation:
The graph of a function and its inverse will always reflect through the line
y = x.
This is because a function has a specific set of coordiates, (x, y). That function's inverse has a set of coordinates that flips the x and y coordinates. For example, if a function has a set of coordinates (0, 1), (2, 3), (4, 5) then its inverse will have the coordinates (1, 0), (3, 2), (5, 4). If you plot the function's points and then the inverse's points in the same plane (meaning on the same graph) and connect the dots, you will see that the function and its inverse are reflections of each other through y = x. Below is an example of this. The dotted purplish line is the line y = x.
f=
4m + 3
m – 1
make m the subject
Answer:
m = [tex]\frac{f+1}{7}[/tex]
Step-by-step explanation:
f = 4m + 3m -1
f = 7m - 1
Adding 1 to both sides
f+1 = 7m
Dividing both sides by 7
m = [tex]\frac{f+1}{7}[/tex]
Answer:
m= (f+3)/(f-4)
Step-by-step explanation:
It is not clear from the question, but I assume it is:
f= (4m+3)/(m-1)so the solution is:
f= (4m+3)/(m-1)f(m-1)=4m+3fm-f= 4m+3fm- 4m= f+3m(f-4)= f+3m= (f+3)/(f-4)What is the following product? StartRoot 10 EndRoot times StartRoot 10 EndRoot

Who knows this, Find m∠UTS, if m∠UTV=x+15, m∠VTS=140∘, and m∠UTS=15x+15
Answer:
165
Step-by-step explanation:
First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.
15x+15=x+155
14x=140
x=10
You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165
pls help i cant find
Answer:
Let's see the first two points: (-7, 5) and (-5, 9)
The line passes these points has a form of: y = Mx + b
=> 5 = (-7)M + b
9 = (-5)M + b
Subtract the 1st equation from 2nd equation, we have:
4 = 2M
=> M = 2
Substitute M back into 1st equation:
=> 5 = (-7)*2 + b
=> b = 19
=> y = 2x + 19
or y - 5 = 2x + 14
or y - 5 = 2(x + 7)
=> Option A is correct
Hope this helps!
:)
Answer:
A
Step-by-step explanation:
The difference between the values of y are constant, that is
17 - 13 = 13 - 9 = 9 - 5 = 4
This indicates the relationship is linear.
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 7, 5) and (x₂, y₂ ) = (- 5, 9) ← 2 ordered pairs from the table
m = [tex]\frac{9-5}{-5+7}[/tex] = [tex]\frac{4}{2}[/tex] = 2
Use any ordered pair from the table for (a, b)
Using (a, b) = (- 7, 5), then
y - 5 = 2(x - (- (- 7)) , that is
y - 5 = 2(x + 7) → A

find the average of the first 4 prime numbers greater than 10
Answer:
The average is mean
Mean is the sum of all the numbers divided by the total so the first prime numbers which are grater than 10 are 11, 13, 17, 19.
So we will add these
11+13+17+19=60
60/4= 15

Step-by-step explanation:
We cant solve by substitution with just one equation

Using the zero product property
3x+2 =0 x-1 =0
3x= -2 x=1

For f(x)=3x+1 and g(x)=x^2-6, find (f•g)(x).
Answer & Step-by-step explanation:
When we see (f * g)(x), it means that we are going to be multiplying f(x) and g(x) together.
f(x) = 3x + 1
g(x) = x² - 6
(3x + 1)(x² - 6)
Multiply each term from the first parentheses to the second parentheses.
3x³ - 18x + x² - 6
Combine like terms and make sure the expression is in standard form.
3x³ + x² - 18x - 6
So, your answer will be letter choice B.

if x=-1\3 is a zero of a polynomial p(x)=27xcube -axsquare -x+3 then find the value of a
Answer:
a = 21
Step-by-step explanation:
If x = h is a zero of a polynomial then f(h) = 0, thus
p(- [tex]\frac{1}{3}[/tex] ) = 27( - [tex]\frac{1}{3}[/tex] )³ - a(- [tex]\frac{1}{3}[/tex] ) - (- [tex]\frac{1}{3}[/tex] ) + 3 = 0, that is
27 (- [tex]\frac{1}{27}[/tex] ) - [tex]\frac{1}{9}[/tex] a + [tex]\frac{1}{3}[/tex] + 3 = 0
- 1 - [tex]\frac{1}{9}[/tex] a + [tex]\frac{10}{3}[/tex] = 0 ( multiply through by 9 to clear the fractions )
- 9 - a + 30 = 0
- a + 21 = 0 ( subtract 21 from both sides )
- a = - 21 ( multiply both sides by - 1 )
a = 21

The human lung has about 80 million alveoli. Give two features of the alveoli that allow large amounts of oxygen to enter the blood.
Answer:
Alveoli forms the respiratory surface in human body.Each alveolus is sac like structure bounded by a single layer of epithelial cells.It is bound on the outside by a network of capillaries. The pulmonary artery from the heart containing deoxygenated blood enters the lungs and then becomes oxygenated after passing in the capillaries through the lungs.
Simplify the expression (3 - 4i)(1 + 5i) - (2 - i). Show your work
Answer: 12i + 21
Step-by-step explanation:
You want to apply foil to the first two terms.
3 x 1 = 35i x 3 = 15i-4i x 1 = -4i-4i x 5i = -20i^2You get 3 + 11i - 20i^2. i is equal to the square root of -1, so when you square it, you will get -1. Then do -1 x -20 to get +20
So far you have (11i + 23) - (-i + 2).
11i + i = 12i23 - 2 = 21Im 99% sure the answer is 12i + 21

Answer:
Divide both sides by 6
or
Multiply 2x-1 by 6
Step-by-step explanation:
18x+30=6(2x-1).
Divide both sides by 6
18x/6+30/6=6/6(2x-1).
3x +5 = 2x-1 or
We could multiply 2x-1 by 6
18x+30 = 6(2x-1)
18x+30 = 12x-6
Answer:
D
Step-by-step explanation:
18x+30=6(2x-1)
My first step would be to distribute the 6 so that the next step you can subtract 30 from both sides.
