Answer:

799/5

Step-by-step explanation:

143+34(3)/5+(13)(3)4/+(11)(3/)5

=143+9/45+(13)(3)/4+(11)(3)/5

=143+9/20+(13)(3)/4+(11)(3)/5

=2869/20+(13)(3)/4+(11)(3)/5

=2869/20+394+(11)(3)/5

=766/5+(11)(3)5

=766/5+33/5

=799/5

What is the y-intercept of the equation of the line that is perpendicular to the line y =
Luda [366]

Answer:

y intercept =10

line y=-x+10

Step-by-step explanation:

Let y=mx+b is the required line.

<u>Slope of perpendicular lines :</u> If m_{1} and m_{2} be slope of two perpendicular lines. Them m_{1}\times m_{2}=-1

y=mx+b is perpendicular to y=x+10

the slope of y=x+10  is =1

m\times 1=-1\\m=-1

Hence eqn is y=-x+b

This equation passes through (15,-5)

-5=-15+b\\b=-5+15\\b=10

so the line is y=-x+10

<u>y-intercept :</u>

Substitute x=10

y=0+10\\y=10

How can u solve y= -x -4 if I don't know my given intercepts
lukranit [14]
To solve you would use the equation y=mx=b .
y is how far line goes up, x is how for along , m is the slope and b is where the line crosses the yaxis.
slope: -1
x-intercept ; -4
y-intercept : -4
