Answer:

The required equation is y=-\frac{1}{3}x+2.

Step-by-step explanation:

The equation of line cd is

y=3x-3

Slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

Slope of line cd is 3.

The product of slopes of two perpendicular lines is -1.

m_1\times m_2=-1

3\times m_2=-1

m_2=-\frac{1}{3}

Therefore slope of perpendicular line is -\frac{1}{3}.

Point slope form of a line is

y-y_1=m(x-x_1)

Slope of perpendicular line is -\frac{1}{3} and line passing through the point (3,1).

y-1=-\frac{1}{3}(x-3)

y=-\frac{1}{3}x+1+1

y=-\frac{1}{3}x+2

Therefore the required equation is y=-\frac{1}{3}x+2.

Y=3x-3 => slope=m=3
The new line perpendicular has slop = -1/m=-1/3
y=-1/3x+b, b is intercept point (3,1)
=>b=y+1/3x=1+(1/3)3=2
=> y=-1/3x+2

Answer:

There are 104.5 centiliters of paint in the mixture.

Step-by-step explanation:

Since you have a total of .50 liters of paint you would just look at the measurement and split it in half which would give you 100 centiliters and then you would add the 4.5 centiliters to the 100 and you would get 104.5 centiliters of paint.

Answer:

3/4 - 5/12

Step-by-step explanation:

first you make the demoninators the same so 3*4=12

and if you *3 you do it to the numerator

so its 9/12-5/12

the unsimplified fraction is 4/12

if wanted simplified version its 1/3
