Answer: The oldest one is Vredfort Crater.

Step-by-step explanation:

The data is:

Chicxulub was formed 6.5x10^7 years ago.

Vredfort was formed 2x10^9 years ago.

Sudbury basin was formed 1.8x10^9 years ago.

Acraman crater was formed 5.8x10^8 years ago.

We want to find the oldest, so we need to find the larger number of the 4 we have.

For this, we need to see at the exponents, the larger the exponent the larger the number.

We have two with a 9 in the exponent:

Vredfort and Sudbury.

Now we look at the number, Vredfort has 2x10^9 and Sudbury has 1.8x10^9.

Both have the same exponent, but the scalar of Vredfort is larger (2 is greater than 1.8) so we have that Vredfort is older.

Use substitution to solve the system of linear equations. In your final answer, include all of your work.
JulijaS [17]
<span>y = -3x + 4
x + 1/3y = 4/3

Substitute the first expression into the second equation for y:

</span>x + 1/3(-3x + 4) = 4/3
x - x + 4/3 = 4/3
4/3 = 4/3

Answer;
All real numbers are solutions.

Hope this helps.
