So, let's start off with explaining what these different questions mean;
y = |x + c| Shifts the graph c units left.
y = |x - c| Shifts the graph c units right.
y = |x| + c Shifts the graph c units up.
y = |x| - c Shifts the graph c units down.
(0,0) Is the starting point on any graph like this. So, determine the answer by going through the list of answers.
I believe the answer is y = 2x.
I would like to know if I am wrong so contact me!!
Answer:
The x- and y-coordinates are switched
Step-by-step explanation:
Here, we want to identify the error in the plot
1.5 units to the left, that is negative x-axis (-1.5)
4 units up is 4
So the coordinate point is (-1.5,4)
So the error on what he gave was that both coordinates were switched
Answer:
Randall=68 pounds, Seth's=40, Joanna's=52
Step-by-step explanation:
Randall's = 3x-7
Seth's = 2x-10
Joanna's = 2x+2
Randall's + Joanna's = 3 (Seth's)
Find X:
- Form into an equation (add parentheses)
- (3x-7) + (2x+2) = 3 (2x-10)
- REmove parentheses on left side
- 3x-7+2x+2 = 3 (2x-10)
- Distribute right side
- = 6x-30
- 3x-7+2x+2 = 6x-30
- Combine like terms
- 5x-5=6x-30
- subtract 5x from BOTH sides (always subtract, add, multiply, and divide both sides at the same time)
- -5=x-30
- Add 30 to BOTH sides
- 25=x
Find how many pounds of trash each friend picked up:
Randall's:
- 3x-7
- plug in x
- 3(25)-7
- Distribute
- 75-7
- = 68
Seth's:
- 2x-10
- 2(25)-10
- 50-10
- = 40
Joanna's:
- 2x+2
- 2(25)+2
- 50+2
- =52
Double check your answers:
Randall's+Joanna's= Seth's(3)
68+52=40(3)
120=120
You're good to go!
Answer:
where is diagram..........???
Answer:
Step-by-step explanation:
- A null hypothesis is a hypothesis where a researcher generally try to disprove, it says that there is no statistically significant relationship between the two variables .
- An alternative hypothesis says that there is a statistical significance between two variables.
Claim 1. : Mean age of online dating service users is 40 years.
i.e. , since it has equals sign so we take this as null hypothesis.
Claim 2. : Mean age of online dating service users is not 40 years.
⇒ Null Hypothesis :
Alternative hypothesis :
