What is the coordinates after (x+2, y + 3)
Answer:
L is (2,4) M (3,1,) N(0,4)
Step-by-step explanation:
L 0+2=2 so x is 2
L 1+3=4 so y is 4
M 1+2=3 so x is 3
M -2+3=1 so y is 1
N -2+2=0 so x is 0
N 1+3=4 so y is 4
Given that f(x) = x2 – 13x + 40 and g(x) = x - 5, find f(x) = g(x) and
express the result in standard form.
Answer:
Step-by-step explanation:
f(x)=g(x)
x²-13x+40=x-5
x²-14x+45=0

Answer:
150
Step-by-step explanation:
Collected bills: 18 * 10= 180
1/6 of 180 = 30
180-30=150
Answer:
15 ten dollar bills, 150 dollars
Step-by-step explanation:

k(x) = x
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.

Match the factors affecting cost to their definitions. Write the name of the factor next to its definition
Answer:

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.

a^2 + b^2 = c^2
2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
3.605 = c
therefore, the answer is 3.605.

Urgent solve this please
Answer:
39.12
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]

. 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

Answer:
so is it 28? i need help too
The surface area of the label is 28 squared inches. Therefore, option A is the correct answer.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
The dimensions of juice box are length=2 inches, breadth=1.5 inches and height= 4 inches.
The lateral surface area of a cuboid is given by 2(length+breadth)×height.
Now, lateral surface area of juice box = 2(2+1.5)×4
= 2×3.5×4
= 28 squared inches
Therefore, option A is the correct answer.

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

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.

Answer:
3( -8 + 1) = 3( -8) + 3(1)
Step-by-step explanation:
That is distributive property
Answer:
3(-8+1)=(3(-8)+(3(1)
Step-by-step explanation:
In this case, distributive property is when a number or you could call it integer, multiplies with another set of number inside parentheses ().
Your answer was wrong, because 6 x 7=42, and that's not equal to the other side of numbers.
The top one is addition, so that's a no.
The second one's not exactly in the form you want it to be for it to be the same as the left side.
The third one shows distributive property in two ways, which give you the same result, so that would be the correct answer.
