Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

Answer:
y-4= -1/2(x-4)
Step-by-step explanation:
First you have to find the slope to write it in point slope
to do this you find change in Y over change in X
From -4 to 4 is postivite 8 and from 8 to 4 its -4
Now you do -4 divided by 8 and get -0.5 or -1/2 for slope now pick one of the points and put it in the formula y-y1=m(x-x1)
The answer to the question :) 17/40=.425
Answer:
D.
90 x 1/2 = 45 km
The rate is 90 miles per hour and 30/60=1/2 so we multiply 1/2
