Which equation represents a proportional relationship that has a constant of proportionality equal to -10

stira [4]

Answer:

$y = - 10x$

Step-by-step explanation:

A proportional relationship has equation:

$y = kx$

where k is the constant of proportionality.

Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.

We substitute k=-10 into the equation to get:

$y = - 10x$

Therefore the correct choice is

$y = - 10x$

ruslelena [56]

Answer:

(a) 65536 - the basic principle of counting

(b) 2520 - use the multinomials.

Step-by-step explanation:

Divide 8 people among 4 schools

The teachers are different among themselves, and so are the schools.

(a)

Every teacher can choose a school. By the basic principle of counting: 4.4.4.4.4.4.4.4 = 4^8 = 65536

different divisions of the teachers

Note: this does not ensure that every school gets a teacher

(b) - Every school gets precisely 2 teachers:

to divide 8 different objects into four groups of fixed sizes 2, 2, 2 and 2, use the multinomial coefficient

( 8 2, 2, 2, 2) = (8!)/(2!2!2!2!) ==> 2520

different divisions of the teachers

barxatty [35]

Answer: 16 miles

Explanation:
I believe it would be 16 miles, if he starts off at 6 miles on day one and goes up 1/2 mile every day, he would be up a mile every other day, basically on day 3 he would be at 7 and day 5 at 8 miles, if the pattern continues he would be at 16 miles by day 21.

How many 2/3 's make up 4 1/5

miskamm [114]

Answer:

6³/₁₀

Step-by-step explanation:

Number of bits = Total amount/Size of each bit

= (4⅕)/(⅔)

Convert the mixed number to an improper fraction

No. = (²¹/₅)/(⅔)

Invert the denominator and change division to multiplication

No. = ²¹/₅ × ³/₂

Multiply numerators and denominators.

No. = ⁶³/₁₀

Convert the improper fraction to a mixed number.

No. = 6³/₁₀

It takes 6³/₁₀ ⅔s to make up 4⅕.
