Answer:
(-15, 14)
Step-by-step explanation:
Let the coordinates of Z be (x,y).
![\frac{x+5}{2}=-5 \implies x=-15 \\ \\ \frac{y+6}{2}=10 \implies y=14](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B5%7D%7B2%7D%3D-5%20%5Cimplies%20x%3D-15%20%5C%5C%20%5C%5C%20%5Cfrac%7By%2B6%7D%7B2%7D%3D10%20%5Cimplies%20y%3D14)
Answer:
(1,-44), (2,-48),(3,-52).......
Step-by-step explanation:
4(1)+y=-40
4+y=-40
y=-40-4
y=-44
(1,-44)

X=numbers of hammers
y=numbers of scewdrivers
f(x,y)= total cost in $
f(x,y)=11x+6.65y
f(4,7)=4(11)+6.65(7)=44+46.55=90.55
Sol: an expresion for the total cost of the tools is f(x,y)=11x+6.65 y;
x=number of hammers
y= number of scewdrivers.
The total cost is $90.55
