Step-by-step explanation:

substitute Y int he first equation with 3x+3 and work it out

3x+3 = -2x-4

x=-7/5

and then use the answer you just got and substitute again and work out till u get answer

Answer:

two solutions

1.x=-7/5;y1=6/5

2.x=-7/5;y2=-6/5

Step-by-step explanation:

y=-2x-4

y=3x+3

-2x-4=3x+3

-5x=7

x=-7/5

y1=14/5-4=(14-20)/5=6/5

y2=-21/5+3=(-21+15)/5=-6/5

(polynomials) multiply. (x^2-5x)(2x^2+x-3)

Nikitich [7]

Answer:

2x^4 - 9x^3 -8x^2 + 15x

Step-by-step explanation:

(x^2-5x)(2x^2+x-3) distribute first

2x^4

x^2 + x = x^3

5 * 2x^2 x= 10x^3

5x^1+1 = 5x^2

5 * 3x = 15x Put them all together

2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms

2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms

= 2x^4 + x^3 - 10x^3 - 8x^2 + 15x more adding terms

2x^4 - 9x^3 -8x^2 + 15x

Hope my answer has helped you, if not i'm sorry.

javier has 3 math books that are the same size. he makes a stack by placing the books on top of each other. The total stack is 1

Alexeev081 [22]

Answer:
The height of one book is $\frac{10}{3}$ in

Explanation:
We know that the 3 books are of the same size. This means that the 3 books have the same height.
Assume that each book has a height x in

Now, we know that the total height is 10 in.
Therefore:
x + x + x = 10
3x = 10
x = 10/3 in

Based on the above, the height of one book is 10/3 in

Hope this helps :)
