Answer:

$d=24h$

Step-by-step explanation:

The table is

h d

1 24

2 48

3 72

4 96

This relation can be presented as the following linear equation

$d=24h$

Because, the distance is defined as the product between the speed and the time. Also, we obtain this relation, by finding the slope of the given vales

$m=\frac{96-24}{4-1}=\frac{72}{3}=24$

Then, using one point, the slope and the point-slope formula, we have

$y-y_{1}=m(x-x_{1})\\y-24=24(x-1)\\y=24x-24+24\\y=24x$

Where $y=d$ and $x=h$ .

Therefore, the expression that models this situation is

$d=24h$

Answer:

Step-by-step explanation:

d = 24 x h

since d is the distance in order to get that we need to multiply the speed times time and get the answer

Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5

y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)

y = 4/5x - 3.6 ( y = mx + b formula)

4/5 = 0.8

y = 0.8x - 3.6

x = 1
y = 0.8(1) - 3.6
y = - 2.8

x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2

x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2

x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4

x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4

etc.

graph using the (x,y)

Identify the prime numbers in the following list 5 7 12 11

Elis [28]

Answer:

Step-by-step explanation:

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.

A prime number has only two divisors: 1 and itself.

Therefore, the prime numbers are:

5, 7 and 11.

12 is not a prime because 12 = 2 × 6 = 3 × 4.
