\frac{ {7x}^{2}  - 5x + 1}{4x + 1}

Step-by-step explanation:

Since the denominators are the same we just have to combine the top.

{x}^{2}  - 5x +  {6x}^{2}  + 1

Combine alike terms.

{7x}^{2}  - 5x + 1

put that over our denominator.

\frac{ {7x}^{2} - 5x + 1 }{4x + 1}

Find the equation of the linear function represented by the table below in slope-
alisha [4.7K]

Answer:

y = 8x + 8

Step-by-step explanation:

The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
