Answer:
slope = -4
Step-by-step explanation:
Given the following points on the graph: (-1, 4) (1, -4)
Let (x1, y1) = (-1, 4)
(x2, y2) = (1, -4)
Use the following slope formula:


Therefore, the slope of the line is -4
Answer:
x = 3.7
Step-by-step explanation:
Apply trigonometric function to find x
Reference angle = 24°
Opposite = x
Hypotenuse = 9
This, apply SOH:
Sin 24 = Opp/Hyp
Sin 24 = x/9
9 × Sin 24 = x
3.66062979 = x
x = 3.7 (nearest tenth)
Yes, because if you have x=5 and x=10 they are parallel lines to each other.
Half of perimeter (or length+ width) is:
222 mm /2= 111 mm.
111 mm- 60 mm= 51 mm
The width of the rectangle is 51 mm~
