Answer:
Step-by-step explanation:
The point-slope form of a line is given as:
Where
m is the slope
is the x-coordinate of the point given (passing through the line)
is the y-coordinate of the point given (passing through the line)
Now,
Given,
Slope = m = 3
= 1
= 2
Now, we simply plug these into the formula for point-slope form of a line:
This is the point-slope form.
f(x) = 24 - 2x
f(2) This means that x is 2, so you can plug in 2 for x
f(x) = 24 - 2x
f(2) = 24 - 2(2)
f(2) = 24 - 4
f(2) = 20
To find x when f(x) = 10, you can do:
f(x) = 24 - 2x [substitute/plug in 10 for f(x)]
10 = 24 - 2x Subtract 24 on both sides
-14 = -2x Divide -2 on both sides
7 = x
Jersey has a tail. is this the right answer?
Call Martha's age 5 years ago is x So Martha father's age five years ago is 7x
We have : 7x + 5 = 4(x + 5)
3x = 25+5=30 so x = 5 so Martha's present age is 10 and her's father's present age is 40
