Answer:

Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to 


substituting the value of y in
:

substituting x=-1 in y= -4-5x:
(upon solving, you should get this)

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)


-1= 2 x 1 +c
-3=c
Answer:
a.) 9.00+3.50= 12.50
b.) 9.00x+3.50
c.) answers below
2. 9.00*2+3.50= 18.00+3.50= 21.50
3. 9.00*3 +3.50= 27.00+3.50= 30.50
4. 9.00*4+350= 36.00+3.50= 39.50
5. 9.00*5+3.50= 45.00+3.50= 48.50

Answer:
No
Step-by-step explanation:
The two shorter lengths won't make a triangle of any kind.
They will simply form a straight line parallel to the base.
Answer: It is Undefined
Step-by-step explanation:
- ㏒(22+4)=log (14-31)
- ㏒(22+4)=log (-17)
Undefined
Simplified that would be: 9(63+12+9) which if you add everything in the brackets, 9(84) which would be 9 times 84=756
