In part 1 we chose
y = 10.4 x + 178
For 48 wheelbarrows,
y = 10.4(48)+180 = 679.2
Answer: 679.2 liters of sand
(-3,-2) are the new coordinates
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:
The answer is c. 6
Step-by-step explanation:
8+40=48
2x2x2=8
48/8=6
6x^2 - x - 40 =(<span>3x - 8)(2x + 5)
and
</span><span>5 + 2x = 2x + 5
</span><span>
so
</span>(6x^2 - x - 40)<span>÷ (5 + 2x)
= [</span>(3x - 8)(2x + 5)] ÷ (5 + 2x)
= 3x -8
answer
3x - 8
