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
Hello!
I'm assuming we're simplifying here
to simplify, use the distributive property of multiplication
2 * 3x = 6x
2 * (-5) = -10
6x - 10 is your simplified answer
I hope this helps, and have a nice day!
Answer:
I can't make out the second half of the problem, but I think that the answer is 3.35g + 0.72f = t
g = granola
f = flour
t = total
Answer:
48 N
Step-by-step explanation:
The equation for force is
F = m * a
where F is force, m is mass, and a is acceleration
30N = m * 5m/s²
m = 6 kg
F = 6kg * 8m/s² = 48 N
