Answer:
-2x^2-5x+150
Step-by-step explanation:
(x)(-2x) + (x)(15) + (10)(-2x)+(10)(15) <--- multiplying
2x^2+15x-20x+150 <---- solution of multiplication
2x^2 - 5x+150 <------- combine like terms (answer)
Answer:
19/40
Step-by-step explanation:
1.9*(1/4) =0.475
0.475=19/40
Answer:
x intercepts: (-1,0) and (2.5,0)
It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)
To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.
Step-by-step explanation:

Answer: He rode 4.8 miles each day.
Variable: x = Constant distance distance traveledd each day.
Equation : 10+5x=34
Step-by-step explanation:
Total distance needs to travel = 34 miles
Distance already traveled = 10 miles
He will ride bicycle for 5 more days.
Let x = Constant distance distance traveledd each day.
Total distance = 10+5x
i.e.

Hence, he rode 4.8 miles each day.
