To solve an equation with a square yo would take the square root of both sides.
(4x - 5)^2 = 49
sqrt((4x - 5)^2) = sqrt49
4x - 5 = + - 7
4x - 5 = 7 and 4x - 5 = -7
4x = 12 4x = -2
x = 3 x = -1/2

Write the following coordinates where they belong in the line segments below. Consider the graph below. Which of the following c
GREYUIT [131]

Answer:

The option B (4 5/8,-2 3/4)  = (4.6 , -2.75) will be the coordinates belonging in the box.

Step-by-step explanation:

A.(4 3/4,-3 3/4) = (4.75,-3.75)

B.(4 5/8,-2 3/4)  = (4.6 , -2.75)

C.(4 1/4,-5 1/2)  = (4.25, -5.5)

D.(4 1/8,-2 3/5) = (4.125, -2.6)

The first point of line segment is: (5.5, -4.25)

second will be (4.75,-3.75)

third will be (4.6 , -2.75)

fourth will be (4.125, -2.6)

and fifth is  (3.75,-1.25)

The option C is not correct i.e not included in line segment.

The option B will be the coordinates belonging in the box.

The question is the second difference the answer box covered it up
Naily [24]

Answer:

The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:

  • d₂ = 3 - 1 = 2
  • d₂ = 5 - 3 = 2

Step-by-step explanation:

Given the table

x                    y

0                   3

1                    4

2                   7

3                   12

The (first) difference, let suppose denoted by d, of y values can be obtained  by taking the difference between consecutive terms.

  • d = 4 - 3 = 1
  • d = 7 - 4 = 3
  • d = 12 - 7 = 5

The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:

  • d₂ = 3 - 1 = 2
  • d₂ = 5 - 3 = 2
