A store mixes Kentucky bluegrass worth $12 per pound and chewings fescue worth $15 per pound. The mixture is to sell for $13 per

quester [9]

The solution for the problem is as follows:

((12x + 15y)/228) = 13
x + y =228

x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:

x = 152
y = 76

Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Answer:

Step-by-step explanation:

P(x) = $\frac{2}{3x-1}$

Q(x) = $\frac{6}{-3x+2}$

P(x) × Q(x) = $\frac{2}{3x-1}\times \frac{6}{-3x+2}$

= $\frac{2\times 6}{(3x-1)(-3x+2)}$

= $\frac{12}{(3x-1)(-3x+2)}$

P(x) ÷ Q(x) = $\frac{2}{(3x-1)}$ ÷ $\frac{6}{(-3x+2)}$

= $\frac{2}{(3x-1)}\times \frac{(-3x+2)}{6}$

= $\frac{(-3x+2)}{3(3x-1)}$

What is 0.464646... as a fraction

rewona [7]

This is what I get

You have to place the decimal numbers over the power of 10.since its 6 places to the right will be 10^6(1000000).

464646/1000000

Now cancel common factors by factoring out 2.

232323/500000=0.464646

What is the equation in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4?

Nimfa-mama [501]

The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:

y+3=4(x+1)

Step-by-step explanation:

Given

m=4

and

Point = (x1,y1) = (-1,-3)

The general form of point-slope equation of line is:

$y-y_1=m(x-x_1)\\Putting the values of m, x_1 and y_1\\y-(-3)=4(x-(-1))\\y+3=4(x+1)$

Hence,

The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:

y+3=4(x+1)
