-9y=-3x+216
y=1/3x-24
m=-3
y=-3x+16 is perpendicular to the line
Answer:
ACB = 85
Step-by-step explanation:
First find x:
10+ x + 60 = 120 - x
x + 70 = 120 - x
Add x to both sides
2x + 70 = 120
subtract 70 from 120
2x = 50
Divide 2 from both sides
x = 25
10 + 25 + 60 = 95
Subtract 95 from 180
ACD = 85
To solve for y you have to simplify both sides of the equation, then isolating the variable which equals to...
y = -4x/3 + 4
Next, you have to move all terms that don't contain y to the right side and solve.
y = 10 + 2x/3
____
Now we solve the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-3,8)
Equation Form: x = -3, y = 8
____
Leaving it to be the only choice which is 'D.) 8', I hope this helps, as always. I wish you the best of luck and I hope you have a nice day..
Answer:
yes they are inverserve of each other
Step-by-step explanation:
f(x) = y just for say
y=3x+9
switch the x and y value and solve for y
x=3y+9
x-9=3y
(x-9)/3 = y
inverserve of f(x) is g(X)
and now g(x) = y
y= (x-9)/3
switch x and y and solve for y
x=(y-9)/3
3x= y-9
3x+ 9 = y
inverserve of g(x) is f(X)
