I think the first one is a simple as it gets
for the second one it could be simplified to 6x^6-4 because u combine the x terms and distribute the power

Let the present age of the father = x
Let the present age of the son = y
Solution
x + y = 60
How many years will pass? You could say it's z.
x + z = y When z years pass, the son will be his father's present age.
x + z + y + z = 120 when z is added to both their current ages, the result is 120 Collect like terms
x + y + 2z = 120
<u>x + y = 60 </u> Subtract The very first equation
2z = 60 Divide by 2
z = 60/2 30 years have passed.
z = 30
x + z = y
x + 30 = y Substitute x + 30 for the present y value (the father).
x + x + 30 = 60
2x = 30
x = 15
x + y = 60
15 + y = 60
y = 60 - 15
y = 45
So the son's age right now is 15
The father's age right now is 45
Answer:
<em>d) The equation of the line passing through the points </em>

Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given points are ( 0, -4) and (2 ,0)
slope of the line

<u><em>Step(ii):</em></u>-
The equation of the line passing through the point ( 0,-4) and having slope



2 ( y +4) = -x
2 y + 8 = -x
2 y = - x - 8


<u><em>Final answer:-</em></u>
<em>The equation of the line passing through the points </em>
