Answer:
1/64
Step-by-step explanation:
There are 8 equal sections
P(1) = 1/8 since there is one section with a 1 out of the 8 sections
Then we spin again
P(2) = 1/8 since there is one section with a 2 out of the 8 sections
P(1, then 2) = P(1) * P(2) since they are independent events
= 1/8 * 1/8
= 1/64
I'm assuming a 1:10 scale. So then that means the 10 by 15 feet should be divided by 10. The blueprint area is 1 ft by 1.5 ft.
x = the age of his son now, then the age of the father is 4x.
In 20 years,
son's age = x + 20
father's age = 4x + 20
solve the equation for x:
4x + 20 = 2(x + 20)
4x + 20 = 2x + 40
2x = 20
x = 10
So the age of his son now is 10, and the age of the the father now is 40.
Answer:
The Answer is: y = -3x - 26
Step-by-step explanation:
Given point: (-6, -8)
Given equation:
y = -3x + 3, the slope m = -3
A parallel line has the same slope, m = 3. Use the point slope form and substitute in the point and the slope:
y - y1 = m(x - x1)
y - (-8) = -3(x - (-6))
y + 8 = -3x - 18
y = -3x - 18 - 8
y = -3x - 26
Proof - use the point (-6, -8):
f(x) = -3x -26
f(-6) = -3(-6) - 26
= 18 - 26 = -8, giving (-6, -8)
