Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.
1/6 x = 2/3 |multiply both sides by 6
x = 12/3
x = 4
Answer:
C
Step-by-step explanation:
Given
C = πd ( isolate d by dividing both sides by π )
= d → C
