Factor x2 – 4x – 5 = 0.<br><br> WITH ALL STEPS.
Troyanec [42]

x²-4x-5=0

The given equation is quadratic

So we can perform prime factorisation of it.

factors of -5, that add up to give -4 are -5 and 1

therefore replacing -4x by -5x+x

x²-5x+x-5=0

performing factoring by grouping,

(x²-5x)+(x-5)=0

x(x-5)+(x-5)=0

(x+1)(x-5)=0

x+1=0 and x-5=0

Answer is x=-1 and x=5

What is the answer to 2/3 - 7/15=
elixir [45]

Answer:

1/5

Step-by-step explanation:

2/3 - 7/15

Now when dealing with fractions, alas make the dominator ( bottom number the same), and the rule of thumb is, whatever u do to the bottom, must be done to the top

2 7

-------- - - - - - -

3 15

So now u should think, how to make 3 to 15, so u multiply it by 5, therefore u would also need to multiply it to the top

2 x 5 7

-------- - - - - - -

3 x 5 15

10 7

-------- - - - - - -

15 15

Now just minus horizontally ( u don't need to minus the dominator)

3

---------

15

Now can u make this fraction smaller? As in, is there a number that u can divide to the top and bottom, yes, that number is 3 in this case

3 ÷3

---------

15 ÷3

= 1

- - - - -

5

Thats your final answer

If g(x)=2x-5 and f(x)=-x+3, which of the following represents f(g(x))?
Slav-nsk [51]

Answer: f(g(x))=-2x+8

*Note: you did not provide answer choices, but this should be the answer.

Step-by-step explanation:

f(g(x)) means you plug in g(x) into f(x).

f(g(x))=-(2x-5)+3

f(g(x))=-2x+5+3

f(g(x))=-2x+8
