which equation is represented by the function table below? x's are 1,2,3,4 y's are 8,14,20,26

Answers

Answer 1

Answer: f: R -> R, f(x) = ax + b;
f(1) = 8 => a + b = 8;
f(2) = 14 => 2a + b = 14 => a = 6 and b =2;
f(3) = 20 => 6*3 + 2 = 20 True;
f(4) = 26 => 4*6 + 2 = 26 True;

then, f:R -> R, f(x) = 6x + 2;

Answer 2

Answer: $\int\limits{(x)} = 6x + 2$

Anu drinks 2 cups of water each day. Jan drinks twice as much water as Anu.How many fluid ounces does Jan drink?

Answers

Simple,

first find out how many fluid ounces there are in 1 cup

1 cup=8 fluid ounces

That means for Anu:

2*8=16

Anu has drunk 16 fluid ounces.

Now, Jan, we know that she drinks 2x (twice) as much as Anu...

So,

4 cups:

4*8=32

Thus, it means that Jan has drunk 32 fluid ounces.

you would have to first find out how many fluid ounces are in on cup and there are 8. then you have to times 8 by 2 and you get how much anu drinks and that is 16 and then you have to times 16 by 2 to get jens

A building with a height of 40 ft casts a shadow that is 16ft long. A person standing next to the building casts a shadow that is 2ft long. How tall is the person?

Answers

16ft long shadow of a building when the building true height is 40 ft
1 ft long shadow of a building when the building true height is 40/16 ft
2 ft long shadow of a person when the building true height is (40x2)/16 = 5ft (ans)

ratio:
40ft / 16ft = 2,5

soo....
x / 2ft = 2,5

answer:
x = 5ft
