Answer: z=6

Step-by-step explanation:

4(z-3)=2z

4z-12=2z subtract 2z from both sides

2z-12=0 add 12 to both sides

2z=12 divide 2 to both sides

z=6

Factorise fully the following:<br>a) x² + 2x<br>b) 2x² - 6x<br>c) 15x - 10x³<br>d) 9x² + 3x³​
Lostsunrise [7]

Answer:

a) x(x+2)

b) 2x(x-3)

c) 5x(3-2x^2)

d) 3x^2(3+x)

Step-by-step explanation:

a) x^2+2x

When factoring a binomial (a polynomial with two terms), what we will be looking for are the terms that are shared between them.

In this problem, it can be seen that both of these terms have and x. This means that we can factor it out to get

x(x+2)

b) 2x^2-6x

What are the common terms here?

It can be seen that each of these share a 2x, so our factored form would be

2x(x-3)

c) 15x-10x^3

What about this one?

The common factor of this one is 5x, so our factored form would be

5x(3-2x^2)

d) 9x^2+3x^3

The common factor of this one is 3x^2, so our factored form would be

3x^2(3+x)

How does the value of b affect the graph of the equation?
slamgirl [31]
Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.
Hope this helped!
