First solve for y with first equation:

3y = 13-6x      so    y = 13/3-2x

Plug that in with 2nd equation:

-9x-4(13/3-2x)=-17

-9x-52/3-8x=-17

-17x=-34 1/3

x = <u>34 1/3 </u>
       17

x = 103/51

Which equation represents the total interest, T, earned when the principal amount is $100, the annual simple
netineya [11]

Answer:

The answer is option (C), T = 100 • 0.1 • 10

Step-by-step explanation:

Total interest (T) earned after a 10 years can be expressed as;

Total interest (T)=Principal amount×interest rate×Number of years

where;

Total interest=T

Principal amount=$100

Interest rate=10%=10/100=0.1

Replacing;

T=100×0.1×10

The equation for calculating the total interest amount after 10 years can be written as;

T = 100 • 0.1 • 10

Algebra Question ( Matrices and Determinants ) 20 point
blagie [28]
The determinant of a 2 x 2 matrix can be calculated as:
Product of non-diagonal elements subtracted from product of diagonal elements.

The diagonal elements in given matrix are 12 and 2. The non-diagonal elements are -6 and 0.

So,

Determinant G = 12(2) - (-6)(0)

Determinant G = 24 - 0 = 24

So, option B gives the correct answer
