Area= l * b
12= 5 * b
b = 12/ 5
b= 2.4 ft
The supplement of 30° is the angle that when added to 30° forms a straight angle (180° ).
Answer:
A.
Step-by-step explanation:
The given equation is

We solve for y by subtracting 3x from both sides to obtain;

We now divide through by -7 to get;

This simplifies to;

This equation is now in the form y=mx +c, where
is the slope.
