So the absolute value of -5 is 5
Hope this helps
Answer:
When you reflect across the x-axis, the x coordinate stays the same. When you reflect across the y-axis, the x coordinate becomes opposite. When you reflect over the origin, both coordinates become opposite.
Step-by-step explanation:
When you look at the coordinate plane, the x-axis is horizontal (side to side) and the y-axis is vertical (up and down). If you reflect across the x-axis, then you are mirroring (flipping) the object over the horiontal line, which means your x value stays the same. If you reflect across the y-axis, you are mirroring (flipping) the object over the vertical line, which means your y value stays the same and the x value must become opposite. When you cross the origin, you are going diagonal across the coordinate plane, which means both the x and y values will become opposite.
Answer:
No solution or x ∈ ∅
Step-by-step explanation:
We have given the equation ⇒ x+12 = (x+14) -3
if we solve this equation ⇒ x+12 = x+14-3
⇒x+12= x+11
⇒12 ≠ 11
which state that x ∈ ∅
i.e. there is no value of x which make the equation true
therefore, No solution
According to the model, the year will the population exceed 470 million is 2060
What is the first step to take?
The first step in this case is to use the model to compute the population figure in each year as shown below:
N = 3.21t + 277.3
Year 2020:
t=20
N = 3.21(20) + 277.3
N=341.50
Year 2025:
t=25
N = 3.21(25) + 277.3
N= 357.55
Year 2030:
t=30
N = 3.21(30) + 277.3
N=373.60
Year 2035:
t=35
N = 3.21(35) + 277.3
N= 389.65
Year 2060:
t=60
N = 3.21(60)+ 277.3
N= 469.90
Year 2065:
t=65
N = 3.21(65)+ 277.3
N= 485.95
Since all the years given do not give the correct year, let us equate the target population figure to the model and solve for t
470= 3.21t + 277.3
470-277.3=3.21t
192.70=3.21t
t=192.70/3.21
t=60.03(approximately 2060)

Our experience with students bringing cell phones and entertainment systems to school has been that too often they go missing (lost or stolen) either in school or on the bus. This creates many issues regarding questioning students and investigating incidents. We feel it is the safest policy for students not to have them in school. As our sites are small, everyone has the ability to make and receive calls to their parents in an emergency. We also feel it can lead to miscommunication if students are being communicated to directly and administration or staff is not also informed.
This should be good
