Answer:
3y+5x=0
Step-by-step explanation:
The question is on equations of parallel lines
Finding the gradient m of line AB
m=change in y coordinates/change in x-co-ordinates
Given points A(-3,0) and B (-6,5)
m=Δy/Δx Δy=5-0=5 Δx=-6 - -3= -3 ⇒m= - 5/3
Equation
The line will have its gradient equal to - 5/3
m=-5/3
point is the origin (0,0)
m=Δy/Δx
y-0/x-0 = -5/3
3(y-0)=-5(x-0)
3y-0= -5x+0
3y=-5x
3y+5x=0
Step-by-step explanation:
1=78°
3= 78°
4= 360°- 78° - 78°
= 204° ÷ 2
= 102°
2= 102°
Note that 1+2+3+4=360°
180° - (4)
= 180° - 102°
= 78° ÷ 2
= 39°
ans; angle ACD is 39°
You can’t simplify that fraction.
Answer:
x=4
Step-by-step explanation:
subtract 8 from both sides
then you get 2x=8
then divide by 2
then you get x=4
Answer: 90 presents in 6 hours.
Step-by-step explanation:
First, you turn the 6 hours into minutes. You should get 360 minutes.
Next, divide 360 by 4 and you get the answer of 90.
--- Your answer is 90 presents.
