Answer:

x = 3/10 + (i sqrt(71))/10 or x = 3/10 - (i sqrt(71))/10

Step-by-step explanation:

Solve for x:

5 x^2 - 3 x + 4 = 0

Divide both sides by 5:

x^2 - (3 x)/5 + 4/5 = 0

Subtract 4/5 from both sides:

x^2 - (3 x)/5 = -4/5

Add 9/100 to both sides:

x^2 - (3 x)/5 + 9/100 = -71/100

Write the left hand side as a square:

(x - 3/10)^2 = -71/100

Take the square root of both sides:

x - 3/10 = (i sqrt(71))/10 or x - 3/10 = -(i sqrt(71))/10

Add 3/10 to both sides:

x = 3/10 + (i sqrt(71))/10 or x - 3/10 = -(i sqrt(71))/10

Add 3/10 to both sides:

Answer: x = 3/10 + (i sqrt(71))/10 or x = 3/10 - (i sqrt(71))/10

You have 3 apples, 4 pears, 7 oranges, and 14 bananas. Your friend gives you 5 times that amount. Your other friend gives you 75
yuradex [85]

Answer:

6384

Step-by-step explanation:

Since the question is only talking about fruit, I'm going to ignore which type and add the fruits together.

3+4+7+14=7+7+14=14*2=28

I have 28 fruits, and my friend give me 5 times that, so my friend gives me 5*28, or 140 fruits. So in all, I have 140 plus my original 28, or 168 all together

Then, my other friend gives me 75 times more. Wow. I don't think I've seen this many fruits all in one place, but this is the world of math, so who cares?

75*168=(70*168)+(5*168)=7000+4200+560+500+300+40=11760+840=

12600 fruits that your friend gives you. In addition to the 168 that you had before. Pardon my french, but why the ...

12600+168=12768 fruits at the height of your fruity domination.

Then, your friend takes half

12768/2=6384 fruits.

Please help me!!!!!!
dusya [7]

Answer:

The green box is -3

Step-by-step explanation:

You are reading from a graph, so it is more important perhaps, to pick clear points rather than easy to handle points.

The easiest two points you could use would be

(0,4)

(1, 1)

Slope

m = (y2 - y1)/(x2 - x1)

y2 = 4

y1 = 1

x2 = 0

x1 = 1

m = (4-1)/(0 -1)

m = 3/-1 = - 3

Y intercept

b = 4    from the point 0,4

Line

y = - 3x + 4
