Answer:

The mother is 40 years old and the son is 16 years old.

Step-by-step explanation:

With a system of equations mentioned in the statement the answer can be reached, we have to:

Let X be the age of the mother, Y the age of the son.

X + Y = 56 (1)

X-10 = 5 * (Y-10) (2)

Solving

 X -10 = 5 * Y - 50

From where:

X = 5 * Y - 40

Substituting in the first equation:

5 * Y - 40 + Y = 56

6 * Y = 56 + 40

Y = 96/6 = 16

Now, replacing the value of Y:

X = 5 * 16 - 40

X = 80 -40

X = 40

Therefore the mother is 40 years old and the son is 16 years old.

What is the y-intercept of f(x)<br> -(1)?<br><br> A. (1,0)<br> B.(1 1/4)<br> C. (0,0)<br> D. (0,1)
Nataly [62]

Y intercept is where our x variable is equal to 0 and where the graph touches the y-axis.

Therefore, you can get the y intercept by just plugging in x = 0. For example, in the linear function: f(x) = 2x + 3, our y intercept would be (0,3) because we just set our x value equal to 0.
