Oxana [17]1 year ago
7 0

Step-by-step explanation:

x + y = 72

x - y = 40

x = y + 40

so, the first equation is then

y + 40 + y = 72

2y + 40 = 72

2y = 32

y = 16

x = y + 40 = 16 + 40 = 56

Artist 52 [7]

Answer: There is no change in the number of state representatives for fourth state after the last census.

Step-by-step explanation:

Here, the Data set {+4,-1,-2,0} shows a change in number of state representatives for four states after the last census.

In the first state the changes is +4, that is, there is an increase of the number of representative in first state by factor four.

In the second state the changes is -1, that is, there is an decrease of the number of representative in second state by factor one.

In the third state the changes is -2, that is, there is an decrease of the number of representative in second state by factor two.

In the fourth state changes is 0, therefore, there is no change in the number of representative in fourth state.

Write (2 4) and (6 16) in the form y=mx+b
Lena [83]

Answer:

y = 3x-2

Step-by-step explanation:

We can find the slope using the formula

m = (y2-y1)/(x2-x1)

  = (16-4)/(6-2)

  =12/4

 =3

We then use the point slope form of a line

y-y1= m(x-x1)

y-4 = 3(x-2)

Distribute the 3

y-4= 3x-6

Add 4 to each side

y-4+4 = 3x-6+4

y = 3x-2

This is in slope intercept form
