The sum of the ages of the father and his son is 42 years. The product of their ages is 185. Find the age of the father and the

Iteru [2.4K]

Let f and s be the ages of the father and the son. We have

$\begin{cases}f+s=42\\fs=185\end{cases}$

From the first equation we derive

$f=42-s$

Substitute this expression for f in the second equation and we have

$(42-s)s=185 \iff -s^2+42s-185=0 \iff s^2-42s+185=0$

The solutions to this equation are s=5 or s=37

Since the sum of the ages must be 42, the solutions would imply

$s=5 \implies f=37,\quad s=37\implies f=5$

We can only accept the first solution, since the second would imply a son older than his father!

What is the linear equation that has slope of 5 and pass through the point (-1, -3)?

Mademuasel [1]

What you would do is that you would use the y=mx+b linear equation
m=5
x=-1
y=-3
b=?
hence, you must solve b to have the equation

-3=(5)(-1)+b
-3=-5+b
-3+5=b
2=b
therefore the equation is
y=5x+2

for standard form you just move everything to equal 0 because there is no fraction next to the x
thus

-5x+y-2=0
