Answer: Albert's grand father is 50 years older that Albert this year.
Step-by-step explanation:
Let x represent Albert's age this year.
Let x represent Albert's grandfather age this year.
This year Albert and his grandfather's ages total to 64 years. This means that
x + y = 64- - - -- - - - - -1
In 3 years, Albert's grandfather will be 6 times as old. This means that
y + 3 = 6(x + 3)
y + 3 = 6x + 18
y = 6x + 18 - 3
y = 6x + 15
Substituting y = 6x + 15 into equation 1, it becomes
x + 6x + 15 = 64
7x = 64 - 15 = 49
x = 49/7
x = 7
y = 6x + 15 = 6 × 7 + 15
y = 57
The difference between their ages is 57 - 7 = 50 years
Your answer would be option C because the red is 36 and the blue is 27 which added together equals 63

Step-by-step explanation:
Answer:
y = 12 
Step-by-step explanation:
The standard form of the exponential function is
y = a 
Find a and b by substituting ordered pairs from the table into the equation
Using (0, 12 ), then
12 = a
( = 1 ), so
a = 12, then
y = 12 
Using (1, 34.8 ) , then
34.8 = 12 
( divide both sides by 12 )
b = 2.9
Thus exponential function is
y = 12
