Answer:
(-31,15)
Step-by-step explanation:
Rotating 90 degrees clockwise is very simple:
(a,b) 90 degrees= (-b,a)
Very simple.
Just switch sides and add negative to the first term.
The median is the one in the middle. Sorting the data gives
$1.61, $1.75, $1.79, $1.84, $1.96, $2.09, $2.11
Seven data points and the fourth one is 1.84.
Answer: $1.84
Answer:
each one contribute 300
Step-by-step explanation:
The computation of the each one contribution is given below:
Given that
There are six ALS learner who shares the apartment
The total bill is 1,800
So based on the above information, the each one contribution is
= Total bill ÷ number of learners
= 1,800 ÷ 6
= 300
Hence, each one contribute 300
Answer:
x⁷ = 60
Step-by-step explanation:

- The expotential equation .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
Given logarithmic equation is ,
⇒ log x⁵ + log x ¹² = 7
⇒ log x ⁵ * ¹² = 7 [ log aⁿ + log aⁿ' = log aⁿ * ⁿ' ]
⇒log x ⁶⁰ = 7
In expotential form we can write it as ,
⇒ x⁷ = 60
x = 3 + y Eqn(1)
y = -2x + 9 Eqn(2)
Let us solve the system of equations with the substitution method
x - 3 = y (Subtracting 3 from both sides of the Eqn(1))
Replacing y = x - 3 in Eqn (2), we have:
x - 3 = -2x + 9
x = -2x + 9 + 3 (Adding 3 to both sides of the equation)
x + 2x = 9 + 3 (Adding 2x to both sides of the equation)
3x = 12 ( Adding like terms)
x = 12/3 (Dividing by 3 on both sides of the equation)
x = 4
Replacing x=4 in Eqn(1), we have:
4 = 3 + y
4 - 3 = y (Subtracting 3 from both sides of the equation)
y=1
The answers are:
x= 4 and y=1
