Answer:

4x + 1

Step-by-step explanation:

(8x + 2) - (4x + 1)

8x-4x=4x

2-1=1

therefore, it would be 4x + 1

What is the y-intercept of the liner function? (y=3x-2)
inysia [295]

The y-intercept of the linear function y = 3x - 2 is -2

<h3>How to determine the y-intercept?</h3>

The function is given as

y = 3x - 2

The above function is a linear function, and the y-intercept is the point on the graph, where x = 0 i.e. the point (0, y)

As a general rule, linear functions are those functions that have constant rates or slopes

Next, we set x to 0, and calculate y to determine the value of the y-intercept

y = 3(0) - 2

Remove the bracket in the above equation

y = 3 * 0 - 2

Evaluate the product of 3 and 0 i.e. multiply 3 and 0

y = 0 - 2

Evaluate the difference of 0 and -2 i.e. subtract 0 from 2

y = -2

The above means that the value of y when x is 0 is -2

Hence, the y-intercept of the linear function y = 3x - 2 is -2

6. What is the greatest common factor of the following expression? *<br> 15y3 – 40y
Nady [450]

Answer:

I'm not sure what 15y3 is, but I'll take a guess.

If the only numbers are 15, 3, and -40, then the greatest common factor is 1.

If the only numbers are 15 and 3, then it's three.

If the only numbers are 15 and -40, it would be 5.
