Answer:

Combine like terms onto one side of the equation

Step-by-step explanation:

You have

-x^2  -4x  - 3  = 2x + 5

It seems that we should combine like terms to make this equations smaller.

-x^2 - 4x - 3  - 2x  - 5 = 0

-x^2  -6x  - 8 = 0

- (x + 2)(x + 4) = 0

x = -2  or  x  = -4

Which ratio is equal to 15:20?
Basile [38]

Answer:

21 to 28

Step-by-step explanation:

Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)

15 : 20 = (5*3) : (5*4) = 3 : 4

_____

21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20

5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4

18 : 25 . . . has no common factors . . . ≠ 3:4

Helpp pls<br><br><br><br> Find the slope, y-intercept, and the equation.
never [62]

Answer:

  1. Take two points
  2. 64-18/97-29=23/34
  3. Now plug that into the equation to find the equation
  4. 97=23/34(29) +b
  5. B is the y intercept
  6. B= 77.38
  7. Hence the equation is y= 23/34(x) + 77.38
