Answer:
Area of a triangle is base x height / 2. First, 6 x 2 is 12. Then you divide by 2 with an outcome of 6.
Step-by-step explanation:
It has an area of 6 yards
Answer:
a. 8x + 4y = −4
17x + 2y = −28
Step-by-step explanation:
{6x + 2y = −6
{3x − 4y = −18
{6x + 2y = −6
{1½x - 2y = −9
___________
[Plug this back into both equations above to get the y-coordinate of 3];
Alternatively, you plug the solution of into the top answer choice to get this:
{−16 + 12 = −4 ☑
{−34 + 6 = −28 ☑
These are genuine statements, therefore this system of equations is the system we are looking for.

Answer:
True
Step-by-step explanation:
If exy=3, then dy/dx will be found as follows:
differentiating our expression implicitly we get:
(x(dy/dx)+y)e^(xy)=0
N/B
when differentiating e^(xy) we apply chain rule. When differentiating xy, we use product rule.
next, we substitute (1, ln(3)) and solve for dy/dx
(1(dy/dx)+ln(3))^(1ln(3))=0
((dy/dx)+ln(3))e^(ln(3))=0
but
e^(ln3)=3, this is because e and ln are inverse of each other.
3((dy/dx)+ln(3))=0
dy/dx+ln (3)=0
dy/dx=-ln(3)
The answer is :
dy/dx=-ln(3)
