How do you tell if a function is linear?

1 answer:

5 0

It is linear when the highest degree of the variable is 1.

For example the function 3x - 2 is linear ( the x has exponent 1 (x = x^1))

For lunch each family purchases some buckets of hot chips and some drinks. The Hayes family buys 2 drinks and 1 bucket of chips

WITCHER [35]

Let d be number of drinks and b be number of buckets of chips

2d+b=11 so we can say b=11-2d

3d+2b=19 and using b from above in this we get:

3d+2(11-2d)=19

3d+22-4d=19 subtract 22 from both sides

-d=-3 divide both sides by -1

d=3, and from earlier b=11-2d so

b=11-6=5

So a bucket of chips cost $5 and a drink costs $3

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Papessa [141]

Answer:

The value of c is 2√2 or about 2.8.

Step-by-step explanation:

We can find the hypotenuse (c) with the help of Pythagoras Theorem.

=> c² = 2² + 2²
=> c² = 4 + 4
=> c² = 8
=> c = √8
=> c = √2 x 2 x 2
=> c = 2√2

If you want further simplification, seek for explanation below.

=> c = 2√2
=> c = 2 x √2
=> c = 2 x 1.414
=> c = 2.828 = 2.8 (Estimated)

Hence, the value of c is 2√2 or about 2.8.

Hoped this helped.
