How to factorise 5x-30

Mathematics
1 answer:
liq [111]3 years ago
8 0

Answer:

5(x+6)

Step-by-step explanation:

hope this is helpful

factorise an expression, we need to take out any factors that are common to each term. The process is the opposite of expanding brackets. To make sure an expression is fully factorised, we need to identify its highest common factor (HCF), ie the biggest number/letter that each term can be divided by.

What is the y-intercept of the line?<br><br> x 16 24 32<br> y 44 64 84
Shtirlitz [24]

Answer:

The y-intercept of the line is 2

Step-by-step explanation:

You could try to find the slope of the line and then find the intercept with y axis by sloving b = y - ax

But here it seems easy enough once you see that the x values in the table increase by a factor of 8 and the y values in the table increase by a factor of 20.

(By the way, this is enough to give you the slope, because it is 8/20 ). But why bother?

Just extrapolate the table to the left, and you will find the y value where x = 0

x 0 8 16 24 32

y 2 22 44 64 84

So the y-intercept of the line is 2.

Extra:

The full equation of the line is:

y = 8/20x + 2
