Answer:
13.8h
Step-by-step explanation:
Answer:
Bb
Step-by-step explanation:
Vertex is at (4,−6)and the axis of symmetry is x=4
9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Answer:
7x = y + 37
Step-by-step explanation:
y = 7x - 9
Differentiating y with respect to x, we have as follows:
dy/dx = m = 7 ( where m is the slope)
Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)
y + 9 = 7(x - 4)
y + 9 = 7x - 28
∴ 7x = y + 37
