Step-by-step explanation:
The first step is to move the like terms to same side of equation
3x + 9 = 17x - 11 ➡ 9 + 11 = 17x - 3x
then we add like terms
20 = 14x simplify if needed
10 = 7x and x = 10/7
A number, x, rounded to 2 significant figures is 1300
Write down the error interval for x.
Answer:
[tex][1250,1350)[/tex].
Step-by-step explanation:
It is given that a number, x, rounded to 2 significant figures is 1300.
It is possible if,
1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e., [tex]1250\leq x\leq 1300[/tex] ...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e., [tex]1300\leq x<1350[/tex] ...(2)
On combining (1) and (2), we get
[tex]1250\leq x < 1350[/tex]
1350 is not included in the error interval for x.
Interval notation is [tex][1250,1350)[/tex].
Therefore, the error interval for x is [tex][1250,1350)[/tex].
What is the next term of the following sequence?
20, 10, 5, 21/2, ...
Answer:
1 [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2 [tex]\frac{1}{2}[/tex] ÷ 5 = [tex]\frac{1}{2}[/tex]
Thus to obtain the next term in the sequence multiply the previous term by [tex]\frac{1}{2}[/tex]
2 [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = 1 [tex]\frac{1}{4}[/tex]

Your school is planning a field trip to a history museum. They are going to rent a large bus for $450. The cost of the ticket to the museum is $15.75. Write an equation to represent this situation. Then, find how many people need to go on the trip for it to cost $40 per person.
Answer:
19
Step-by-step explanation:
To write an equation for the first situation, you need to determine which factors can be changed. The bus will not change since you can have multiple people in one. The ticket to the museum is per person. This will change depending on how many people there are.
450 + 15.75x
For the second equation, you need to find how many people can go for it the cost to be equal to $40 per person. Set the equation equal to $40 per person and solve.
450 + 15.75x = 40x
450 = 24.25x
x = 18.56
Round up to 19 since you can't 0.56 of a person.

What are simultaneous linear equations?Simultaneous linear equations can be defined as the two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
3x-y=9 - - - -(1)
4x+y=5 - - - - (2)
Adding equations 1 and 2
7x = 14
x = 2
Now, we have
3(2) - y = 9
-y = 9 - 6
-y = 3
y = -3
Thus, the solution of the given simultaneous equations are x = 2 and y = -3.

The graph of y=54x+1 is shown below. The coordinate (0,y) is a solution of the equation. Given the x-value of 0, what is the value of the y-coordinate for the coordinate (0,y)?
Answer: y =1
Step-by-step explanation:
Evaluating the equation for x = 0:
y = 54 (0) + 1
y =1
The y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The missing figure is attached to the picture.
Calculataing the equation for x = 0:
y = 54 (0) + 1
y = 1
Thus, the y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

Which equation represents a line which is parallel to y = 0?
A. y = 6
B. x = -5
C. y = x
D. y = x - 1
Answer:
A. y = 6
Step-by-step explanation:
Y= 0 is equation of x - axis
equation of any straight line which is parallel to x-axis and at distance of a from it is given y = c.
Therefore, from the given option only option A y =6 is in form of y = a and hence is the correct answer.
_______________________________________
Also we know that for two lines to be parallel , their slope should be equal.
slope of line y = mx + c is m
slope of y = 0 here m = 0, hence slope is 0
out of the given option
only for y - 6 slope is 0 and hence it is the correct answer.

solve 5x^2-4x-2=0 by completing the square
Answer:
Hello
Here's the answer:
2x^2 + 5x + 2 = 0\\ 2x^2+4x+x+2=0\\ 2x(x+2)+1(x+2)=0\\ (2x+1)(x+2)=0\\ x=-\frac{1}{2} \vee x=-2
x^2-4x+1=0\\ x^2-4x+4-3=0\\ (x-2)^2=3\\ x-2 =\sqrt3 \vee x-2=-\sqrt3\\ x=2+\sqrt3 \vee x=2-\sqrt3

Are the events of drawing a rook from the bag of white
pieces and then drawing the king from the bag of
black pieces dependent or independent events? Find
the probability of this compound event.
Answer:
Independent events, 1/16
Step-by-step explanation:
What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.
Which means that they are independent events.
And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.
4) Grant had an account balance of $550 in her checking account. Over the next month, he deposits $25, pays his annual credit card fee of $100.00, and makes ATM withdrawals of $200.00 and $80.00 from an ATM that charges a $2.50 fee per transaction. What is his account balance at the end of the month?
Enter your answer as a number, for example: 260
Answer:
190
Step-by-step explanation:
550 + 25 = 575
575 - 100 = 475
475 - 202.5 = 272.5
272.5 - 82.5 = 190
The account balance at the end of the month would be; 190 dollar.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
We have given that Grant had an account balance of $550 in her checking account.
Then he deposits $25,
550 + 25 = 575
So he pays his annual credit card fee of $100.00,
575 - 100 = 475
Then he makes ATM withdrawals of $200.00
475 - 202.5 = 272.5
Then $80.00 from an ATM that charges a $2.50 fee per transaction.
272.5 - 82.5 = 190
Therefore, the account balance at the end of the month would be; 190 dollar.

Rationalize the denominator by multiplying both denominator & numerator by the conjugate of the denominator.

4(2x-3)+8(x-4)=2(2x+6) help plzzz
Answer:
x = 14/3
Step-by-step explanation:
4(2x-3)+8(x-4)=2(2x+6)
Distribute
8x -12 +8x - 32 = 4x +12
Combine like terms
16x -44 = 4x+12
Subtract 4x
16x-4x -44 = 4x+12-4x
12x -44 =12
Add 44 to each side
12x-44+44 = 12+44
12x = 56
Divide each side by 12
12x/12 = 56/12
x = 14/3
