Answer:
(1, No, No) (2, No, Yes) (3, 6x^2+10) (4, 2x^2-3) (5, x^2-x) (6, -2x^4+12x+3)
(7, 3x^3+15x^2+20) (8, 9x^3 + 4x^2+8x) (9, xy+2x+6y+5) Sorry didn't have an answer for 10. I hope they are all correct sorry for the wait.
Step-by-step explanation:
9. (57)
10. 12/7 OR 1.714285
11. 207
12. 8
13. 7/2 OR 3.5
14. -15/16 OR -0.9375
15. 12x - 7
16. -9m - 25
17. -9w + 56
18. 12x - 8y
19. -5a + 15b
20. -11xy +8x -6
IF YOU NEED THE WORK FOR ANY FEEL FREE TO ASK BUT ALL I DID WAS PLUG IN VALUES AND/OR DISTRIBUTE
hope this helps you :)
Let us assume the common ratio to be = x
Then
7x + 8x = 45
15x = 45
x = 45/15
= 3
Then the two numbers are
7x :8x
7 * 3:8 * 3
21: 24
Then the two numbers are 21 and 24.
I hope the procedure in which
the problem is done is clear to you. This is a simple but effective way of
solving such problems. In future this method will make you confident about
solving these kind of problems.
Answer:
y=2x+0
Step-by-step explanation:
Answer:
y = 2x-5
y=-x+4
Step-by-step explanation:
Just need to solve the:
x+y=4
y-2x=-5
And we have:
x=3
y=1
Then replace x and y into the answer to find the correct one
