Answer:
x=e^2/5
Step-by-step explanation:
log(20 x) - log(4) = 2
Add log(4) to both sides:
log(20 x) = 2 + log(4)
Cancel logarithms by taking exp of both sides:
20 x = 4 e^2
Divide both sides by 20:
And we get Answer:
x = e^2/5
The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
Let's check all functions.
1. The function f(x)=x²<span>+2x when evaluated with 3 gives you the value of 3:
Evaluated with x means that</span> x = 3.
f(3) = 3² + 2 * 3 = 9 + 6 = 15
15 ≠ 3, so, this is not correct.
2. f(x)=x²<span>-3x when evaulated with -3 give you the value of 3
Evaluated with -3 means that x = -3.
(f-3) = (-3)</span>² - 3 * (-3) = 9 + 9 = 18
18 ≠ 3, so, this is not correct.
3. f(x)=x²<span>+2x when evaluated with -3 gives you the value of 3
</span> Evaluated with -3 means that x = -3.
f(-3) = (-3)² + 2 * (-3) = 9 - 6 = 3
3 = 3, so this is correct.
4. f(x)=x²-3x when evaluated with -3 gives you the value of 3
Evaluated with 3 means that x = 3.
f(3) = (3)² - 3 * 3 = 9 - 9 = 0
0 ≠ 3, so this is not correct.
Wouldn't be four because theres only four aces
or it could be 16 due to the fact that theres four of each 4 kings and queens and jacks and '10's'
but I'm gonna say that its would be four not sure if thats the answer but thats what i think
Answer:
A. The expression of "40 times the sum of 24 and 36" would be 40 x (24+36), and the value would be 2400.
B. for the words portion it would be "20 times the sum of 650 and 350", and the value of that expression is 20,000.
C. The expression of "divide the difference between 1,600 and 400 by 4" should be 1200 / 4, and if that is the correct way to format the expression then the value would be 300.
D. for the words portion it would be "100 times the sum of 78 and 12", and the value of that expression is 10,000.
