Answer:
x = -2
Step-by-step explanation:
Since we know they will have the same output, we can set them equal to each other in an equation. We'll use x to represent the input.
3x + 6 = 8(x + 2) (Given)
3x + 6 = 8x + 16 (Distributed the 8)
6 = 5x + 16 (Subtracted 3x on both sides)
-10 = 5x (Subtracted 16 on both sides)
-2 = x (Divided 5 on both sides)
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x
Answer:y.5
Step-by-step explanation:5 times 3 = 15/2 = 7.5
Answer:
Step-by-step explanation:
1) √2 + 2√2 = ( 1 + 2 ) √2 = 3*√2 = 3√2
4) √8 + √2 = √2*2*2 + √2 = 2√2 + √2 = ( 2 +1 ) √2 = 3√2
7) 2√5 - √5 = (2 - 1)√5 = 1 √5
10 3√5 - 2√5 = (3 - 2) √5 = 1√5
