Answer:
17 times
Step-by-step explanation:
Let "x" be the number of times today's investment is more than the investment 10 years ago
Investment 10 years ago = 1.25*10^3 = 1,250
Investment today = 2.125*10^4 = 21,250
So, we can form the equation as shown below:
1250*x = 21,250
x = 21,250/1,250
x = 17
Therefore, today's investment is 17 times greater than the investment 10 years ago
Answer:
Step-by-step explanation:
Let the equation of the line 'a' is,
y = mx + c
Here, m = slope of the line
c = y-intercept
For line 'a',
Slope of the line =
m =
m =
y-intercept = 20
Therefore, equation of the line 'a' is,
y =
Similarly, equation of the line 'b' is,
y = m'x + c'
Slope of the line =
m' =
m' =
y-intercept = 0
Therefore, equation of the line is 'b' is,
y =
1). Line 'b' represents a proportional relationship → FALSE
2). The constant of proportionality of y to x for line 'a' is → FALSE
3). The ratio of y-coordinate to x-coordinate of one of the points on line b is 25 : 8 → FALSE
4). let a passes through the point so the constant of proportionality is → TRUE
Answer:
the slope is whatever value is by itself. so thats 4
