That looks like a translation; let's check. We have
A(-5,1), B(-3,7), A'(3,-1), B'(5,5)
If it's a translation by T(x,y) we'd have
A' = A + T
B' = B + T
so
T = A' - A = (3,-1) - (-5,1) = (8,-2)
and also
T = B' - B = (5, 5) - (-3, 7) = (8,-2)
They're the same so we've verified this transformation is a translation by (8,-2), eight right, two down.
The older brother was born three years before the young one, which means that their age will always differ by 3. Don't be fooled by the fact that, in this particular year, the age of the older brother is exactly twice the age of the younger! This is not a property that will be carried on with the years: for example, next years bother A will be 4 and brother B will be 7, and 4 is not half of 7!
So, since the property that remains constant is the three year gap, when brother B (the older one) will be 60 years old, brother A will be 3 years younger, as always, which means that he will be 57.
Answer:
1/4
Step-by-step explanation:
The product of 9 and the sum of a number and 1 is calculated as; 9 *(x + 1)
<h3>How to express algebra word problems?</h3>
We want to find out the product of 9 and the sum of a number and 1.
Now, it is vital to know that when dealing with algebraic word problems we have to take proper note of the algebraic variables and the given mathematical operations.
Now, we are told that the product of 9 and the sum of a number and 1. Let the unknown number be x and as such we can say that the expression of the given algebraic statement is given as;
9 *(x + 1)
Thus we conclude that the product of 9 and the sum of a number and 1 is calculated as; 9 *(x + 1)
