Answer:
a=-26,b=-10,c=-1,d=-2
Step-by-step explanation:
when x=-3
y=-(-3)^2 +4(-3)-5=a
a=-9-12-5
=-14-12
=-26
when x=-1
y=-(-1)^2 +4(-1)-5=b
=-1-4-5
b=-10
when x=2
y=-(2)^2 +4(2)-5=c
=-4+8-5
=-9+8
c=-1
when x=3
y=-(3)^2 +4(3)-5=d
=-9+12-5
=-14+12
d=-2
Answer: The correct option is D: Is alloyed with carbon and chromium to make stainless steel.
Explanation: Because of its physical characteristics, iron is a material that tends to oxidize easily. With the chromium alloy stainless steel is created, which for its quality can be used in the manufacture of structural steels.
Positive integer factors of 100:
1, 2, 4, 5, 10, 20, 25, 50, 100
Now find if they are a multiple of 2 or 3.
2, 4, 10, 20, 50, 100
That is 6 factors.
