Please help me with this quadratic equation question! I always give out 5 stars, thanks and brainliest to people that help me wi

Answer:

$p=25,\\q=12$

Step-by-step explanation:

In $(ax+b)(cx+d)=acx^2+bcx+dax+bd$ , notice the third term of the quadratic in standard form is formed entirely by $b\cdot d$ .

Therefore, in $12x^2 - 13x - 7175 = (x-p) (qx + 287)$ :

$-p\cdot287=-7175,\\-p=\frac{-7175}{287},\\p=\fbox{$25$}$ .

Now that we found $p$ , we must find $q$ . The first term of the quadratic in standard form is formed entirely by $ax\cdot cx$ . Therefore:

$1\cdot q=12, \\q=\fbox{$12$}$ .

The inequality x - y > 0 is satisfied by point (-1, 1).<br><br> T/F

Mekhanik [1.2K]

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Step-by-step explanation:

We need to identify the point (-1,1) satisfies the inequality x - y > 0

Solving:

The value of x = -1 and y =1

Putting values in the inequality:

$x-y>0\\-1-1>0\\-2>0\,\,false$

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

One pipe fills a storage pool in 8 hours. A second pipe fills the same pool in 4 hours. When a third pipe is added and all three

steposvetlana [31]

The first pipe fills 1/8 of a pool in one hr.
The second pipe fills 1/4 of a pool in one hr.

(1/8+1/4)2= 3/4 done by the first two pipes in 2 hours.
Therefore the last pipe must do 1 1/4 of the filling in 2 hours, which is 5/8 per hour.

5/8x=1
x=8/5

It takes the third pipe 1 hour and 36 minutes to fill it by itself.
