Use the drop-down menus to complete each equation so the statement about its solution is true. 5−4+7x+1

Mathematics
1 answer:
leva [86]3 years ago

Answer:

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Step-by-step explanation:

Simplifying

5 + -4 + 7x + 1 = 7x + 1

Reorder the terms:

5 + -4 + 1 + 7x = 7x + 1

Combine like terms: 5 + -4 = 1

1 + 1 + 7x = 7x + 1

Combine like terms: 1 + 1 = 2

2 + 7x = 7x + 1

Reorder the terms:

2 + 7x = 1 + 7x

Add '-7x' to each side of the equation.

2 + 7x + -7x = 1 + 7x + -7x

Combine like terms: 7x + -7x = 0

2 + 0 = 1 + 7x + -7x

2 = 1 + 7x + -7x

Combine like terms: 7x + -7x = 0

2 = 1 + 0

2 = 1

Solving

2 = 1

Find the value of x if A, B, and C are collinear points and B is between A and C.
Andrew [12]

Answer:

x = 6

Option A.

Step-by-step explanation:

We know that

If A, B and C are collineal points, they all pass through a common line.

<--------------14-------------->

A-----------B----------------C

<-----x-----><------x+2---->

Based on the problem and the diagram above,

(x) + (x+2) = 14

(2x+2) = 14

(2x) = 12

(x) = 6

Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.
ycow [4]

This  involves quite a lot of arithmetic to do manually.

The first thing you do is to make the first number in  row 2  = to 0.

This is done by R2 = -3/2 R1 + R2

so the matrix becomes

( 2        1          1)    ( -3 )

( 0    -13/2   3/2)   (1/2 )

(5       -1           2)  (-2)

Next step is to make  the 5 in row 5  = 0  

then  the -1  must become zero

You aim  for the form

( 1 0 0) (x)

(0 1 0) (y)

(0 0 1) ( z)

x , y and z will be the required solutions.
