Answer:
Step-by-step explanation:
The point slope form of a straight line is expressed as
y - y1 = m(x - x1)
Where
m represents slope of the line
y1 represents the initial value of y
x1 represents the initial value of x
If two lines are parallel, it means that they have the same slope. From the equation of the given line, slope = 1/2
Therefore,
m = 1/2
x1 = - 3
y1 = - 2
Substituting into the point slope equation, it becomes
y - - 2 = 1/2(x - - 3)
y + 2 = 1/2(x + 3)
The equation is
y + 2 = 1/2(x + 3)
We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
Number 1 is B and number 2 I belive is C. I hope I'm rightt, and I hope this helps.
Answer: It would be C and D
Step-by-step explanation:
By the phythagorean theorem, the 2 legs would equal to the hypothesize.
Choice A would not form a triangle.
Choice B does not follow the pythagorean theorem. 84 plus 16 does not equal 100.
Choice C does. 8 + 121 = 129.
Choice D does. 1 + 3 = 4.
