Answer:
f(4) = 3
x = -1
Step-by-step explanation:
Line graphed shows a linear function.
Since this line passes through two points (4, 3) and (-1, 4)
Let the function is,
f(x) = mx + b
where 'm' = slope of the line
b = y-intercept of the line
Slope 'm' =
=
=
f(x) =
Since a point (4, 3) lies on the line,
f(4) =
3 =
b = 3 + 0.8
b = 3.8
Therefore, f(x) = -0.2x + 3.8
For x = 4
f(4) = -0.2(4) + 3.8
= -0.8 + 3.8
= 3.0
For f(x) = 4
4 = -0.2x + 3.8
0.2x = 3.8 - 4
x =
x = -1
There are 100 centimeter in 1 meter
10 x 100 = 1000
10 meters is more, by 1 centimeter
hope this helps
31 out of 50 is
62%Divide 31 over 50:
Multiply 0.62 and 100. This will convert the decimal to a percentage:
8090kg-4854kg=decrease in kg ----- find the difference
3236=decrease in kg
3236kg/8090kg=percent decrease ----- decrease/original amount
0.4= percent decrease ------ percent decrease in decimal form
0.4*100=percent decrease ------ multiply by 100 to get percent form
40% decrease
