Answer:
y=3x+28
Step-by-step explanation:
so a line perpendicular to one with a slope of 1/3 would have a slope of 3/1 which is just 3
so your line would be y=3x+b
to find b you just plug in the coordinates of the point that you want it to pass through into x and y. Remember that points are written as (x,y)
10=3x-6+b
10=-18+b
28= b
the equation is y=3x+28
Answer:
x intercept = 16
y intercept = 4
Step-by-step explanation:
For the x intercept...y = 0...where the equation would be...x + 4(0) = 16..hence giving us the x intercept as... x = 16
For the y intercept...x = 0...where if we substitute x = 0 into our equation...the equation would be....0 + 4y = 16..hence giving us..., 4y = 16...divide both sides by 4...y = 4
Answer:
x= -10
Step-by-step explanation:
So because the angle 55 is part of the same line as one of the unknown angles you can do 180-55 to find that first angle at the top, which is 125.
Next add all three angles (125 + x + 35 + x + 40)=180
Combine the x values to get 2x and subtract the three values from 180
Then 2x= -20, x should be equal to -10
You can plug x back into the values and check your work by adding all the values again, making it all equal to 180 degrees again
