Answer:
<em>m=-1/2</em>
Step-by-step explanation:
The equation is in y=mx+b form. M is the slope. In this equation, -1/2 is m.
Therefore the slope is -1/2.
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
area = 30x + 30(x+3) + 30(2x)
= 30x + 30x+90 + 60x
= (120x + 90) m²
length of planting area = x + (x+3) + 2x = 4x+3 m
area = 30(4x+3) = (120x + 90) m²
x = 5
maple area = 30(5+3) = 240 m²
locust area = 30(2·5) = = 300 m²
