Answer:
2 : 5
Step-by-step explanation:
2 days of the week begin with the letter T (Tuesday, Thursday).
5 days of the week do not begin with the letter T (Sunday, Monday, Wednesday, Friday, Saturday).
The ratio of those that do to those that do not is ...
(begin with T) : (do not begin with T)
2 : 5
1 times 10^1=10
1 times 10^-1=1/10
1 times 10^-2=1/100
1 ten thousandth is 1/10,000, that is 1 times 10^-4
answer is
1*10⁻⁴
Answer:
x=1 and y= -4
Step-by-step explanation:
step one: plug -4x into y in thi]e first equation.
2x+5(-4)= -18
step two: solve for x
2x-20= -18
(add 20 to both sides to eliminate -20 on the right)
2x=2
(divide both sides by 2 to get x by its self)
x=1
step 3: now that we found the value for x plug it in to either equation and solve for y
y= -4x
y= -4(1)
y= -4
Answer:
Step-by-step explanation:
You have the following exponential expression:
You need to divide both sides of the equation by 2:
Now apply the function Natural logarithm to both sides of the function:
Note that now the exponential function is transformed into a logarithmic function.
By definition:
Because the base of the Natural logarithm is the Euler's number "e".
Then you can solve for "x":
