how many solutions does 9x-18=3(3x-6)have?
Answer:
0
Step-by-step explanation:
9x-18=3(3x-6)
3(3x-6)=9x-18
9x-18=9x-18
9x-9x=0
-18+18=0
Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
9x - 18 = 3 (3x - 6)
The equation 9x - 18 = 3 (3x - 6) has infinitely many solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
Example:
2x + 3 = 5
2 x 1 + 3 = 5
2 + 3 = 5
5 = 5
Where x = 1 is a solution.
We have,
9x - 18 = 3 (3x - 6)
9x - 18 = 9x - 18
Whatever value we put for x we will always get the same in both sides of the equation which means the equation is satisfied.
We see that the equation is equivalent.
This means the equation will have infinitely many solutions.
Thus,
The equation 9x - 18 = 3 (3x - 6) has infinitely many solutions.

Identify the axis of symmetry of the function graphed below.
x=-4
x=-1
x=-3
x=1
Answer: -1
Step-by-step explanation: The axis of symmetry of a parabola is a line where the parabola is symmetrical. So it basically 'cuts' the parabola in half. In this case, the axis of symmetry would be -1.

5d - 7 - d + 4 please help!
Answer:
4d−3
Step-by-step explanation:
5d−7−d+4
Combine 5d and −d to get 4d.
4d−7+4
Add −7 and 4 to get −3.
4d−3
The simplified expression is 4d - 3.
Given is an expression 5d - 7 - d + 4 we need to simplify it,
We know that,
An expression is a combination of numbers, variables, and operations that can be evaluated to produce a value.
It can represent a mathematical relationship or a computation.
To simplify the expression 5d - 7 - d + 4, we can combine like terms.
First, let's group the terms with the variable "d" together:
(5d - d) - 7 + 4
Simplifying within the parentheses:
4d - 7 + 4
Combining the constants:
4d - 3
Therefore, the simplified expression is 4d - 3.

Answer: 25.52771
Step-by-step explanation:
i got this answer and it was right :D
The required answer would be 25.48271 if 25.48271 increased by 45 thousandths.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
We have been given that 25.48271 increased by 45 thousandths.
Therefore, 25.48271 + 45/1000
⇒ 25.48271 + 0.045
⇒ 25.52771
Hence, the required answer would be 25.48271.

A student answered 49 problems on a test correctly and received a grade of 98%. How many problems were on the test, if all the problems were worth the same number of points?
Answer:
50 questions.
Step-by-step explanation:
if you divide 100 by 49 you get 2.04 round down, each question is 2 points per question and the student got a 98% then just multiply 49 by 2 just to make sure, then go up. 50 times 2 is 100%, so the answer is 50 questions

Alex's times for running a mile are Normally distributed with a mean time of
5.28 minutes and a standard deviation of 0.38 seconds. Chris's times for
running a mile are Normally distributed with a mean time of 5.45 seconds
and a standard deviation of 0.2 seconds. Ten of Alex's times and 15 of Chris's
times are Tandomly selected. Let x Overbar Subscript Upper A Baseline
minus x Overbar Subscript Upper C represent the difference in the mean
times for Alex and Chris. Which of the following represents the shape of the
sampling distribution for x Overbar Subscript Upper A Baseline minus x
Overbar Subscript Upper C?
Answer: Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds. Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds. Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris. Which of the following represents the shape of the sampling distribution for x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C?
Normal, because both population distributions are Normal.
Uniform, because the both sample sizes are less than 30.
Skewed right, because the difference in times cannot be negative.
Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.
Step-by-step explanation: Can someone tell me the answer?
Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.
Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds.
Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds.
Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris.
What is the standard deviation?The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
Normal, because both population distributions are Normal.
Uniform, because both sample sizes are less than 30.
Skewed right, because the difference in times cannot be negative.

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults
Answer:
The number of adults tickets sold equals 52.
Step-by-step explanation:
First, we need to establish the system of equations:
x= number of adults tickets sold
y= number of kids tickets sold
10x + 6y= 928
x + y=120
Now, we isolate x in one equation and change it in the other to obtain its value:
x= 120 - y
10(120 - y) + 6y = 928
1,200 - 10y + 6y = 928
272 = 4y
68 = y
x= 120 - 68= 52

The distance between the points(-3, -5) and (2,7) on the coordinate plane is given as 5^2+ t^2. what us the value of t
Answer:
Step-by-step explanation:
so we can use [tex]t^{2}[/tex] + 25 as one expression and the find the distance between the points and set the expression equal to that number. That's our strategy.
dist = the square root of [tex]x^{2}[/tex] + [tex]y^{2}[/tex]
where x and y are the change in x2 to x1 and y2 to y1
P1 = ( -3, -5)
P2 = (2, 7 )
dist = square root of ( [2 -(-3) ]^2 + [7-(-5)]2)
dist = sq rt ( 5^2 + 12^2 )
dist = sq rt ( 25 + 144)
dist = sq rt (169)
dist = 13
now set our eq. equal to that number
[tex]t^{2}[/tex] + 25 = 13
[tex]t^{2}[/tex] = -12
this is looking kinda bad, do you know complex numbers?
t = 0 + j 3.46410
