How does 2(3m+6) compare to 5(2m+3)-4m when m is a postive intenger .
Answer:
5(2m+3)-4m is 3 less than 5(2m+3)-4m
Step-by-step explanation:
How does 5(2m+3)-4mcompare to 5(2m+3)-4m when m is a postive intenger .
Expand 2(3m+6) and 5(2m+3)-4m
For 2(3m+6)
= 2(3m)+2(6)
= 6m+12
For 5(2m+3)-4m
= 5(2m)+5(3)-4m
= 10m+15-4m
= 10m-4m+15
= 6m+15
Take their difference
6m+15 -(6m+12)
=6m-6m+15-12
= 3
Hence 5(2m+3)-4m is 3 less than 5(2m+3)-4m

Domain of k: x > 0
Range of k: y > 0
Answer:
1. All real numbers
2. All real numbers
3.x>=0
4.y>=-6
Step-by-step explanation:
The domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a functions g(x) and k(x)
g(x) = x - 6
The domain of the function:
D: x ∈ (-∞, ∞) or
All real numbers.
k(x) = √x
The domain of the function k(x) is x ≥ 0
The range of the function k(x) is y ≥ 0
The sum of the functions:
= g(x) + k(x)
= x - 6 + √x
= x + √x - 6
The domain of the function is x ≥ 0
The range of the function is y ≥ -6
Thus, the domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

Step-by-step explanation:
One of the properties of a rectangle is that every angle in it is congruent. This means that when a diagonal is drawn (a segment connecting opposite corners), a right triangle is formed. One can apply the Pythagorean theorem, this theorem states the following;
[tex]a^2 + b^2 = c^2[/tex],
Where (a) and (b) are the legs, or segments adjacent (next to) the right angle, and (c) is the hypotenuse (the side opposite the right angle).
The legs of the right triangle formed by the diagonal in a rectangle will be the sides of the rectangle. Using this knowledge, one can state the following,
[tex]a^2 = b^2 = c^2\\\\21^2 + 33^2 = c^2[/tex]
Simplify,
[tex]441 + 1089 = c^2\\\\1530 = c^2[/tex]
Inverse operations,
[tex]1530 = c^2\\\\39.1152=c[/tex]

On Monday, mark ran 1 1/3 miles to school and then 2 1/5 miles to his grandmother’s house after school. On Tuesday, he ran twice as much as the previous day. How far did mark run on Tuesday?
On Monday Mark ran for a distance of [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of [tex]\frac{106}{15}[/tex] miles.
What is a fraction ?
A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.
It is given that on Monday , Mark ran [tex]1\frac{1}{3}[/tex] miles to school and then [tex]2\frac{1}{5}[/tex] miles to his grandmother's house.
This meant the total distance he ran on Monday can be calculated by adding both the distances he travelled on the particular day i.e.,
= [tex]1\frac{1}{3}[/tex] miles + [tex]2\frac{1}{5}[/tex] miles
= [tex]\frac{4}{3}[/tex] miles + [tex]\frac{11}{5}[/tex] miles
Now , to add two fractions we need to equal denominator.
= [tex]\frac{20+33}{15}[/tex]
= [tex]\frac{53}{15}[/tex] miles
Now , on Tuesday he ran twice as much as Monday. So , the distance he ran on Tuesday is equal to :
= 2 × [tex]\frac{53}{15}[/tex] miles
= [tex]\frac{106}{15}[/tex] miles
Therefore , on Monday Mark ran for a distance of [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of [tex]\frac{106}{15}[/tex] miles.

Finding missing angle. PLEASE HELP ME!
Answer:
x=147°
Step-by-step explanation:
1. Analyze: The angle opposite to the 33 degree angle is 33 degrees because they are vertical angles.
2. Make an equation: The sum of all four angles (x, the angle opposite of x, the 33 degree angle, and the angle opposite of the 33 degree angle) is 360°. Therefore the equation would be (33°x2)+2x= 360°.
3. Solve for x:
a. Multiply 33 by 2
66+2x=360
b. Subtract 66 from both sides
66+2x=360
-66 -66
2x=294
c. Divide both sides by 2
[tex]\frac{2x}{2} =\frac{294}{2}[/tex]
x=147
4. Remember to add your label- the degree sign (°)
x=147°

Jenae changed the original coffee labels with plain white ones that had the flavor printed in bold black letters, and she placed them on the coffee pots for the week-long experiment. Jenae used an aspect of experimental design known as ________ when she created the labels to have the same appearance.
Answer:
Control group.
Step-by-step explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
A control group generally makes an experiment to work because they are not exposed to the variables and a neutral treatment.
In this scenario, Jenae changed the original coffee labels with plain white ones that had the flavor printed in bold black letters, and she placed them on the coffee pots for the week-long experiment. Jenae used an aspect of experimental design known as control group when she created the labels to have the same appearance.

. Express the ratios in its simplest form (a) 15:12 (b) 42:1
Find the value of "x" in the following 2:x :: 4:6
Answer:
See answers below
Step-by-step explanation:
Given the following ratios. We are to express them in their simplest forms
15:12
= 15/12
= (3*5)/(3*4)
= 3/3 * 5/4
= 5/4
b) 42:1
= 42/1
= 42
Given that 2:x :: 4:6
2/x = 4/6
Cross multiply
4x = 2*6
4x = 12
x = 12/4
x = 3
Hence the value of x is 3
