Natasha's age is 81 years and Andrew's age is 31 years
Step-by-step explanation:
- Step 1: From the given details, let the age of Natasha be x, then age of Andrew is x - 50.
- Step 2: Form equations out of their details of ages 6 years ago.
⇒ x - 6 = 3(x - 50 - 6)
⇒ x - 6 = 3(x - 56)
⇒ x - 6 = 3x - 168
⇒ 2x = 162
⇒ x = 81
- Step 3: Calculate Andrew's age
x - 50 = 81 - 50 = 31
Answer:
the desired equation is y = 3^x
Step-by-step explanation:
if x = 2, then y = 9, and 9 is 3². If x = 4, y = 81 = 3^4.
Therefore we can conclude that the desired equation is y = 3^x
Answer: y=x^8-x^7+x^6-x^5+x^4+x^3+x^2+3
Step-by-step explanation:
here is an example function that satisfies the requirement:
y=x^8-x^7+x^6-x^5+x^4+x^3+x^2+3
if you plug in x=0,
you get y= 3, which satisfies (0,3)
if you plug in x=1,
you get y = 1 - 1 + 1 - 1 + 1 + 1 + 1 + 3,
you get y=6, which satisfies (1,6)
Answer:
Width = 16.875 inches
Step-by-step explanation:
We given that the ratio of the Length/Width = 8/3, and that the length is 45 inches long, so 45/Width = 8/3. Therefore solving for the Width by cross multiplying gives: Width = 3L/8 = 3*45/8 = 16.875
