Step-by-step explanation:
Just do as the problem says:
xy-y = (2)(5)-(5) = 10-5 = 5
Answer: 5
Step-by-step explanation: All you have to do is substitute x & y for their respective numbers. In this case, change x for 2 & y for 5, So xy-y becomes 2(5)-5, which equals 10-5, which is 5.

What is the property of 4x+6=18
Answer: 4x-6= 18
4x=24
x= 24 & 4
x=6
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
I'm not exactly sure of what you mean by property but I think it might be associative property of multiplication?
But to solve for x you would subtract 6 from 18 which gives your 12. Then you divide by 4 to get the x alone and 12/4 is 3.

Which of the following is being constructed in the image?
A. a line parallel to a given line through a point, not on the line
B. a line perpendicular to a given line through a point not on the line
C. a line segment that is congruent to a given segment
D. a perpendicular bisector of a line segment
Alright, sorry for possibly wasting the answer, but its either D or B. i think its D, because its a bisector of the line segment, but B reads that it IS perpendicular, but on points not the line. You can rule out which one of the two it is, i would suggest asking a teacher for help or waiting for a better and more reliable answer.
Sorry if this doesn't help, if it does could I have Brainliest? Bless you, have a nice day.

There are six checkout tills at a small supermarket. Two of the tills have comfy seats. What is the probability an employee will get a till with a comfy seat?
Give your answer as a fraction
Please can someone help thank you very much :)
Answer:
1/3
Step-by-step explanation:
2/6 means that 2 out of the 6 tills have comfy seats. 2/6 simplified is 1/3
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The total amount of tilts is 6
The amount of tilts with comfortable seats is 2
So there are two tilts with comfortable seats out of six tilts that are in the supermarket
Now write it as fraction:
[tex]\frac{2}{6}[/tex] = [tex]\frac{2*1}{2*3}[/tex] (alternatively 2/6)
Here we get the probability
// divide numerator and denominator by 2
[tex]\frac{2*1}{2*3}[/tex] = [tex]\frac{1}{3}[/tex] (alternatively 1/3)
Which boxes have a volume of 120 cubic feet? Box A: length of 5 ft, width of 4 ft, height of 6 ft Box B: length of 7 ft, width of 7 ft, height of 6 ft Box C: length of 3 ft, width of 6 ft, height of 4 ft Box D: length of 10 ft, width of 3 ft, height of 4 ft
Answer:
Boxes A and D have a volume of 120 cubit feet.
Step-by-step explanation:
First, we just have to find the volume for each box so we do...
The volume of box A is:
(Length) x (Width) x (Height) = 5 ft x 4ft x 6ft = 120 [tex]ft^{3}[/tex]
The volume of box B is:
(Length) x (Width) x (Height) = 7ft x 7ft x 6ft = 294 [tex]ft^{3}[/tex]
The volume of box C is:
(Length) x (Width) x (Height) = 3ft x 6ft x 4ft = 72 [tex]ft^{3}[/tex]
The volume of box D is:
(Length) x (Width) x (Height) = 10ft x 3ft x 4ft = 120 [tex]ft^{3}[/tex]
Now we can see that boxes A and D have a volume of 120 cubit feet.

f(x)=−x 2 −4x−19 find f(-9)
Answer:
64
Step-by-step explanation:
The value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function is f(x) = x² −4x−19. The value of the function at f(-9) will be calculated as:-
f(x) = x² −4x−19
f(-9) = ( -9 )² - ( 4 x --9 ) - 19
f(-9) = 81 + 36 - 19
f(-9) = 98
Therefore, the value of the function f(x) = x² −4x−19 at the value x = -9 will be 98.

Select the most appropriate response. An event A will occur with probability 0.4. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.20. We may conclude Question options: that events A and B are independent. that events A and B are dependent. that either A or B always occurs. that events A and B are mutually exclusive.
Answer:
Events A and B are dependent
Step-by-step explanation:
If A and B are two events such as A and B are dependent then
P(A∩B) [tex]\neq[/tex] P(A) P(B)
An event A will occur with probability 0.4 that is [tex]P(A)=0.4[/tex]
An event B will occur with probability 0.6 that is [tex]P(B)=0.6[/tex]
[tex]P(A)P(B)=0.4(0.6)=0.24[/tex]
The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20
Therefore,
P(A∩B) [tex]\neq[/tex] P(A) P(B)
So,
events A and B are dependent
According to the given probabilities, it is found that events A and B are dependent.
What are independent events?Two events, A and B are independent, if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
In this problem, the probabilities given are:
[tex]P(A) = 0.4, P(B) = 0.6, P(A \cap B) = 0.2[/tex]
The multiplication is:
[tex]P(A)P(B) = 0.4(0.6) = 0.24[/tex]
Since [tex]P(A)P(B) \neq P(A \cap B)[/tex], the events A and B are dependent.
