Answer:
y = -0.4 + c
Step-by-step explanation:
y = mx + c (original form)
m ⊥ - 1/m
2.5 = 25/10
25/10 ⊥ -10/25
-10/25 = -0.4
y = -0.4x + c
Answer:
to convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) : x = r × cos( θ ) y = r × sin( θ )
Step-by-step explanation:
Answer: x=-3
Step-by-step explanation:
2x-4(x+3)=x-3
2x-4x-12=x-3
-2x-12=x-3. add 12 to both sides
-2x=x+9. subtract x from both sides
-3x=9. Divide both sides by -3
x=-3
