Answer:
Define F as fathers age and S as sons age right now.
Then now they are
(1) 3S = F
and six years ago they were
(2) 5*(S-6) = F-6
calculate 5*(S-6)
5S - 30 = F-6
Subtract left and right side by -F
Add 30 to left and right side
5S - F = 24
Put (2) 3S = F into the equation above
5S - 3S = 24
2S = 24
S = 12
insert result in (2) 3S = F
3*12 = F
36 = F
Step-by-step explanation:
So the son is 12 years, and the father is 36 years.
As the slope is -1, so any line that has the same slope is parallel.
<u>Solution:</u>
Given points (2, -7) and (4, -9) find the slope, m:
Any line that has the same slope is parallel.
Let's input the x value (5) and see if the output is correct (-1).
y = 2(5) - 11
y = 10 - 11
y = -1
(5, -1) is a solution to y = 2x - 11.
The only ordered pairs that are a solution to y = 8x are (2, 16), (1, 8), and (-3, -24).
y = 8(2)
y = 16
y = 8(1)
y = 8
y = 8(-3)
y = -24
The formula to working out the exterior angle of a polygon is this:
360 divided / (number of sides)
So, let’s use this formula to work out the answer.
360 / 7 = 51.4 to the nearest decimal place
