Answer:
13
Step-by-step explanation:
f(x) = 10/2 + 8 = 5 + 8 = 13
So,
Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6
Just use the slope to find the points you need.
The y-intercept is
(0,-4).The slope is
. Finding the next point:
(-6,0)You could have also used the <em>slope intercept method.</em>
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
The probability is 0.0668 that a product is assembled in less than 12 minutes.
Let the age of Jen 2 years later be x,
age of jack two years later = 2x
total age of jack and jen now = 2x + x - 2 - 2
= 3x - 4
3x - 4 = 66
3x = 70
x = 70/3
= 23.3 (to three significant figures)
age of jen now = x - 2
= 23.3 - 2
= 21.3
Jen is 21.3 years old now.
