Answer:
2
/5
x+
7
/5
Step-by-step explanation:
Add 1 on both sides, then multiply 2 on both sides as well
Left with 5x=20, divide 5
X=4
Answer:
3.07, 3.072, 3.7, 3.72 (the last option)
Step-by-step explanation:
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
