In this question, we have to find the algebraic expression of Six less than the square of the sum of 5 and a number.
And here the number is x.
Sum of 5 and a number x is represented as
And the square of sum of 5 and the number x is
And finally it is six less than the expression we got above, that is
Therefore out of the four options, correct option is A .
Answer:
$3474.25
Step-by-step explanation:
Use the compound amount formula A = P(1 + r)^t. Here r is the rate as a decimal fraction and is -0.15. t represents the number of y ears. P is the initial value of the car.
Then: A = ($15,000)(1 - 0.15)^9, or
A = ($15,000)(0.85)^9 = $3474.25
the expression is 27a^3 or (3a)^3
Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
3x + y = 5 → (1)
5x - 4y = - 3 → (2)
Rearrange (1) expressing y in terms of x by subtracting 3x from both sides
y = 5 - 3x → (3)
Substitute y = 5 - 3x into (2)
5x - 4(5 - 3x) = - 3 ← distribute and simplify left side
5x - 20 + 12x = - 3
17x - 20 = - 3 ( add 20 to both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Substitute x = 1 into (3) for corresponding value of y
y = 5 - 3(1) = 5 - 3 = 2
Solution is (1, 2 )
Answer:
y=0.1(3)^x
