Answer:

Step-by-step explanation:

from equ. of a straight line

y=mx+c

put x=-4 , y=-2 (first row)

-2=-4m+c

-4m+c=-2 ------- 1

put x=2, y=4 (forth row)

4=2m+c

2m+c=4 -------- 2

solving equ 1 and 2 simultaneously

-4m+c=-2

2m+c=4

2m-(-4m) +(c-c)=4-(-2)

6m=6

m=1

put m in equ. 2

2(1)+c=4

c=4-2

c=2.

from y=mx+c

y=(1)x+2

y=x+2

A is the correct option

SCORPION-xisa [38]

Answer:

37.36%

Step-by-step explanation:

Each year it increases 1.6%.

So year 1 it increases (1+1.6%), year 2 increases (1+1.6%)^2 and so on...

so after 20 years, overall increase is found by 1.016^20 = 1.3736 or increase of 37.36%

A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose fr

quester [9]

Answer: She could create 60 platters.

Step-by-step explanation:

Given: A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose from.

Number of combinations of selecting <em>r</em> things from <em>n</em> things is given by:-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

So, the number of combinations of selecting 2 different vegetables from 6 = $^6C_2=\dfrac{6!}{2!4!}=\dfrac{6\times5}{2}=15$

Now, By Fundamental counting principle, the number of different platters she could create = (number of ways of selecting 2 different vegetables from 6) x (Number of sizes)

= 15 x 4

= 60

Hence, she could create 60 platters.
