Answer:
Step-by-step explanation:
3x^2 - 5x + 12 - (5x^2 + x - 11) =
3x^2 - 5x + 12 - 5x^2 - x + 11 =
-2x^2 - 6x + 23 <====
Answer: X=2.7
Step-by-step explanation:
25*2-8x=12x-4
50-8x = 12x-4
subtract 50 from both sides
-8x = 12x-54
subtract 12x from both sides
-20x= -54
divide both sides by -20
X=2.7
Answer: where are the options?
Step-by-step explanation:
Answer: (1,2) and (-1,4)
Step-by-step explanation:
Slope = 
The slope of the line given is - 1
Checking which of the ordered pair has the same slope , the formula will be used to check , and the only pair that will give - 1 is (1,2) and (-1,4)
Answer:
all real numbers
Step-by-step explanation:
The graphs of positive and negative x^2 parabolas will always have a domain of all real numbers. Even though you only have a portion of the graph and see a "restriction" on your domain values, it is incorrect to assume that the domain is limited to what you can see. As the branches of the parabola keep going up and up and up, the values of x keep getting bigger and bigger and bigger. Again, this is true for all + or - parabolas. ....... Can consider brainlist*:)
