Answer:
=(3x+4)
Step-by-step explanation:
Answer:
75 seconds or 1 minute and 15 seconds
Step-by-step explanation:
300 meters/4 mps = 75 seconds
With functions, you take the number that is in the ( ), so we have f(-2), and take the fomula f(x) = 0.8(2 – x) and everywhere you see an 'x' replace it with the -2 f(–2)=0.8(2 – (-2))
We will have to work with the expression of 0.8(2-(-2) When you want to evaluate these types of expressions, you want to use the Order of Operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First we have to evaluate the parentheses. What is 2-(-2)
its 4.
ok now you got 0.8 (4)
Now we have the remains of 0.8(4). If a number is within the parenthesis, then it means that we have to multiply the number inside with the number that is outside. What is 0.8*4 its 3.2 soooo your answer is going to be
3.2
Answer:
r = - 
Step-by-step explanation:
The common ratio r is the ratio between consecutive terms in the sequence.
r = 
= 
= 
= 
= -
1\2-1\8= get the lcm of 2 8=8
(8\2+1=5)(8\8+1=1)
5\8-1\8=4\8=1\2
