As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.
Therefore to find the population of Italy in the year 2000 (t = 10 years) substitute t = 10 in the equation and have:
million people
To find the population of Italy in 2008 (t = 18 years)
substitute t = 18 in the equation and have:
million people
To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30
t = 25
million people
t = 30
million people
Answer:
the first one is A
b/c when you calculate it comes 0 = 6
And the second one is D
b/c when you calculate it comes 0 = 2
if it's helpful ❤❤❤
THANK YOU.
a) x – 2y + 6 = 0 b) x + y = 1 c) y = 1 d) y = -3x + 8
<h3><u>Solution:</u></h3><em><u>a. The points (-4,1) and (2,4) both lie on the line</u></em>
The general line equation on which (a, b) and (c, d) lies is:
Here the given points are (a, b) = (-4, 1) and (c, d) = (2, 4)
Thus the required equation is:
On solving we get,
<em><u>b.) m= -1 and the point (2, -1) lies on the line</u></em>
The equation of line in point slope form is y – b = m(x – a)
where m is slope and (a, b) is a point on it
Here m = -1 and (a, b) = (2, -1)
Thus the required equation is:
y – (-1) = -1(x - 2)
y + 1 = -x + 2
y = -x + 2 -1
y = -x + 1
<em><u>c. )It has the same slope as y = 5 and passes through (1, 1)</u></em>
our line has same slope with y = 5, then our equation would be y = k and it passes through (x, y) = (1, 1) so, then by substitution
1 = k
k =1
Then our equation will be y = k
y = 1
<em><u> d. ) m= -3 and it has a y-intercept of (0, 8)</u></em>
line equation in slope intercept form is y = mx + b where m is slope and b is y – intercept.
Then, our equation will be y = -3x + 8
We took y- intercept = 8 as it is the value of y when x = 0
Answer:
B. m = , y-int = 3
Step-by-step explanation:
To find the slope of the line, we need to plot two points
(2, 6) (-2, 0)
m = slope
Then use the Slope-Formula to Solve for the slope
m =
m =
m =
m =
m =
The Slope is
The y-intercept is 3 because the line is going 3 units upwards on y axis!
Equation: y = 3/2x + 3
Slope: 3/2
y-intercept: 3
