Answer:
a) 20
Step-by-step explanation:
Use similar triangles.
2/3 = x/30
3x = 2 * 30
3x = 60
x = 20
Answer: a) 20
Answer:
12.30 x 6 = 73.8
Step-by-step explanation:
(0,5)(3,-1)
slope = (-1 - 5) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(use either of ur points...(0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = -2(0) + b
5 = b
so ur line is : y = -2x + 5
