Answer:

No

Step-by-step explanation:

First solve both equations:

1) 9x = 5x + 4

Simplifying

9x = 5x + 4

Reorder the terms:

9x = 4 + 5x

Solving

9x = 4 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

9x + -5x = 4 + 5x + -5x

Combine like terms: 9x + -5x = 4x

4x = 4 + 5x + -5x

Combine like terms: 5x + -5x = 0

4x = 4 + 0

4x = 4

Divide each side by '4'.

x = 1

Simplifying

x = 1

2) 14x = 4

14x = 4 (divide both sides by 14 to get x)

14x/14 = 4/14

x = 0.285714285714

As you can see, the value of x in the second equations is less than one, therefore making these algebraic equations not equivalent.

Answer:

No

Step-by-step explanation:

9x=5x+4 and 14x=4

9x= 5x+4

Subtract 5x from each side

9x-5x = 5x+4-5x

4x= 4

The equations are not the same

Here’s a graph of a linear function. Write the equation that describes that function.
lord [1]

Answer:

y = 5x - 5

Step-by-step explanation:

It appears that the graph intersects the y-axis at (0, -5).  This point is the y-intercept of the line.

As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10.  Thus, the slope of the line through these two points is

m = rise / run = 10 / 2  = 5.

The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5

  sales = book price × number of books

  sales = $24 × 157 . . . . . . . . books sold on Saturday

  sales = $3768 . . . . . . . . . . . sales on Saturday

-2 4/5 + 1/4 equals what ?
vlada-n [284]
Hey there! :)

Since 2 4/5 is greater than 1/4, the answer is negative.

You can just subtract 2 4/5 and 1/4 and add the (-) sign

2 4/5 - 1/4

Change the fractions so they can have a common denominator: 20

2 4/5 = 2 16/20

1/4 = 5/20

2 16/20 - 5/20 = 2 11/20

Add the (-) sign → -2 11/20

Answer ⇒ -2 11/20

What is the slope of the linear function represented in<br> the table?<br> -7
Minchanka [31]

Answer:

The function is linear; therefore, the slope of the line joining any two points is the same. We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).
