Help!!! will give brainlyest if explained

Mathematics
1 answer:
7nadin3 [17]3 years ago
8 0

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 2 → (1)

4x + y = 24 → (2)

Multiplying (1) by - 2 and adding to (2) gives

- 4x + 6y = 4 → (3)

Add (2) and (3) term by term

(4x - 4x) + (y + 6y) = (24 + 4), that is

7y = 28 ( divide both sides by 7 )

y = 4

Substitute y = 4 into either of the 2 equations

Substituting y = 4 into (2)

4x + 4 = 24 ( subtract 4 from both sides )

4x = 20 ( divide both sides by 4 )

x = 5

Thus the answers x = 5 and y = 4 are the same as her first method

Which is a factor of x2 + 8x – 48? (x – 6) (x + 4) (x – 16) (x + 12)
MaRussiya [10]

Answer:

(x+12)

Step-by-step explanation:

The middle number is 8 and the last number is -48.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 8

Multiply together to get -48

Can you think of the two numbers?

Try -4 and 12:

-4+12 = 8

-4*12 = -48

Fill in the blanks in

(x+_)(x+_)

with -4 and 12 to get...

(x-4)(x+12)

But, since (x-4) isn't an option, the answer would be (x+12)

If someone could explain this to me that be really great :p
BigorU [14]
"x" always goes on the left side and "y" always goes on the right side of the parentheses. If you only have an "x" then you will just put a zero in for "y" and vice versa. I hope this helps.
