Answer:
A. The sum of 2 and the quotient of 3 and y.
Step-by-step explanation:
We have been given an expression: . We are asked to choose the correct statement about our given expression.
We will use order of operations (PEMDAS) to answer our given problem.
P = Parenthesis.
E = Exponent.
M = Multiplication
D = Division
A = Addition
S = Subtraction
According to order of operations division comes before addition, so our expression will be: , which is the sum of 2 and the quotient of 3 and y.
Therefore, option A is the correct choice.
Answer:
Option A is correct (17,11).
Step-by-step explanation:
6x - 9y = 3
3x - 4y =7
it can be represented in matrix form as
A=
X=
B=
i.e, AX=B
or X= A⁻¹ B
A⁻¹ = 1/|A| * Adj A
determinant of A = |A|= (6*-4) - (-9*3)
= (-24)-(-27)
= (-24) + 27 = 3
so, |A| = 3
Adj A=
A⁻¹ = /3
A⁻¹ =
X= A⁻¹ B
X=
X=
X=
X=
x= 17, y= 11
solution set= (17,11).
