Answer:
6
Step-by-step explanation:
x/8 = 9/12
We can use cross products to solve
x*12 = 8*9
12x = 72
Divide each side by 12
12x/12 = 72/12
x=6
Answer:
y= 3x + 7 Step-by-step explanation:
y= -1/3x+3 (so, gradient of this line is -1/3).
formula: gradient of line one x gradient of line two= -1 (applies for 2 perpendicular lines only).
So, m1 x -1/3= -1
m1= (
)
m1= 3 (gradient of perp line)
y=mx+c
4= 3 x -1 + c
7=c
therefore, y=3x+7 (eqn of the line perp to y=-1/3x+3)
