Answer:
Step-by-step explanation:
Use the quadratic formula first; find the roots, and then write the factors based upon the roots. Here, a = 4, b = -8 and c = -5. Thus, the discriminant b^2 - 4ac is (-8)^2 - 4(4)(-5), or 64 + 80, or 144.
Thus, we have:
-(-8) ± √144 8 ± 12
x = --------------------- = -------------- = 5/2 and x = -1/2
2(4) 8
If x = 5/2 is a root, then (2x - 5) is a factor.
If x = -1/2 is a root, then (2x + 1) is the other factor.

Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
32-8y-39x = 6y-6x
32-8y-6y-39x+6x = 0
-33x-14y+32 = 0
Answer:
Step-by-step explanation:
m = 3
(1 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x - 1)
y - 6 = 3x - 3
y = 3x - 3 + 6
y = 3x +3
Standard form:
-3x + y - 3 = 0
Answer:
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the amount of paint Julio needs for each house is:
Then, since Julio need to paint 18 houses, you have to mulltiply 3.2 gallons by 18 in order to calculate the number of gallons he should buy to paint 18 houses.
Therefore, you get this result:
So, Julio should buy of paint.
