Answer:

y = 1.4x - 28/5

Step-by-step explanation:

slope intercept form: y = mx + b

m - slope

b - y-intercept

slope = rise/run

slope = 7/5

y-intercept - point at which the x-coordinate is 0

0 = 7/5 * 4 + b

0 = 28/5 + b

-28/5 = b

plug in

y = 7/5x - 28/5

simplify

y = 1.4x - 28/5

Answer:

  • y = 1.4x - 5.6

Step-by-step explanation:

<u>Slope-intercept form:</u>

  • y = mx + b

<u>Use two points on the line:</u>

  • (4, 0) and (9, 7)

<u>Find the slope:</u>

  • m = (7 - 0)/(9 - 4) = 7/5 = 1.4

<u>Find the y-intercept:</u>

  • 0 = 4*1/4 + b
  • b = - 5.6

<u>The line is:</u>

  • y = 1.4x - 5.6

Including Jose, there are eight people in his family.
SIZIF [17.4K]

Answer:

840

Step-by-step explanation:

Since the order matters, we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this question:

The first seat is Jose's.

The remaining four are organized among the other 7 members. So

P_{(7,4)} = \frac{7!}{(7-4)!} = 840

So the correct answer is:

840
