Answer: the 4th boy is 11
Step-by-step explanation:
Let's denote the age of the boys as: x₁, x₂, x₃, x₄.
Then,
Multiply both parts of the equation by denoting by 3:
x₁+x₂+x₃=15(3)
x₁+x₂+x₃=45
Hence,
Multiply both parts of the equation by denoting by 4:
45+x₄=14(4)
45+x₄=56
45+x₄-45=56-45
x₄=11
I can't exactly graph it for you but I can tell you how it looks like :-)
So, your graph would have a positive slope that is 4/3. The y-intercept is below the x-axis at -1/3. From that point, the next point to the right would be (3, 11/3). Basically it would go up 4 and right 3 from your y-intercept. I hope this helps :-)
Answer:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
Step-by-step explanation:
Unit price - price of one
0.95/5= 0.19p

The two functions are
y= f(x), ------------(1)
g(x)= f(x+2)---------(2)
⇒Consider a point (a,b) on the curve.It will satisfy (1).
b = f(a)
Now the point a is translated by 2 units right in horizontal direction and there is no vertical shift.
Coordinate of new point = (a+2,b)
Putting the value of new coordinate in equation (1), we get
b = f(a+2)
which gives equation (2), which is
g(x)= f(x+2)
Option (3) is correct,which is, the graph of g(x) is graph of f(x) translated 2 units right.
