Answer:
no solution (parallel lines)
Step-by-step explanation:
You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...
The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
3x^2 -6x + 6 :) hope this is alright
Answer:
Step-by-step explanation:
A triangular pyramid has a base with an area of 21.8 square meters, and lateral faces with bases of 7.1 meters and heights of 9 meters. Enter an expression that can be used to find the surface area of the triangular pyramid.
The expression is written as:
Surface Area = Area of the base + 1/2( Perimeter × Slant height)
Answer:
1 1/6
Step-by-step explanation:
1 is nothing but 6/6
So then you would have 6/6+1/6
then you would do 6+1=7
And keep denominator same
So you have 7/6
Which is the same 1 1/6
Because 6 goes one time into 7/6
But you still have 1/6 left
