Could you make this easier to read, perhaps by ensuring that you have copied the original problem exactly?
What I read, which may or may not be correct, is:
15x^2 - 35x + 24.
I graphed this on my calculator and found that the graph, a parabola opening up, never touches or crosses the x-axis. Thus, the given equation has no real roots.
If you were to find the discriminant, b^2 - 4ac, you'd find that it's negative, which is another strong clue that there are no real roots.
Answer: 49.7
Step-by-step explanation:
<u> 7</u> X 71 = <u> 497</u> = 49.7
10 10
Answer:
x=10
Step-by-step explanation:
group like terms
13x+5x+7x+8x+24+7+2+-3=360
33x+30=360
33×=360-30
33x=330
divide both sides by 33
x=10
It would be 40°F, the temperature drops down 2 degrees in one hour, and theres 3 hours til 3:00am, so it dropped 6° then it would 28°F, then it adds 3° every hour until 7:00am, which is 4 hours, so that would be 28°F+12°F= 40°F
