C=1 because you are flipping it over the line so it cant be negative

Correct answer is not c=1, because when the graph is flipped that would point to y=x.

HELP ASAP : Find the largest value of n such that 5x^2+nx+48 can be factored as the product of two linear factors with integer c

Anna71 [15]

Answer:

$n=241$

Step-by-step explanation:

We are given

$5x^2+nx+48$

Let's assume it can be factored as

$5x^2+nx+48=(5x-s)(x-r)$

now, we can multiply right side

and then we can compare it

$5x^2+nx+48=5x^2-5rx-sx+rs$

$5x^2+nx+48=5x^2-(5r+s)x+rs$

now, we can compare coefficients

$rs=48$

$5r+s=-n$

$n=-(5r+s)$

now, we can find all possible factors of 48

and then we can assume possible prime factors of 48

$48=-+(1\times 48)$

$48=-+(2\times 24)$

$48=-+(3\times 16)$

$48=-+(4\times 12)$

$48=-+(6\times 8)$

Since, we have to find the largest value of n

So, we will get consider larger value of r because of 5r

and because n is negative of 5r+s

so, we will both n and r as negative

So, we can assume

r=-48 and s=-1

so, we get

$n=-(5\times -48-1)$

$n=241$

Simplify the expression -2( p + 4) 2 - 3 + 5p

solmaris [256]

Answer:

p - 19

Step-by-step explanation:

multiply the bracket by -2*2(-4) , -4p - 16 - 3 +5p , 5p - 4p= p & -3 - 16=-19

so exp is p - 19

What is the length of BC?<br> pls help

zheka24 [161]

It’s an isosceles triangle, so those two sides are equal:

3x-15=x+33
2x=48
x=24, so BC should be 24.

The average commute to work (one way) is 25 minutes according to the 2005 American Community Survey. If we assume that commuting

Stolb23 [73]

Answer:

1. 0.1635

2. 0.0026

Step-by-step explanation:

The computation of the probability in the following cases are as follows:

1.

Given that

Mean = 25 minutes

ANd, the standard deviation is 6.1 minutes

So here the z score would be

= (31 - 25) ÷(6.1)

= 0.98

Now the probability is

= P(Z>0.98)

= 0.1635

2. the z score would be

= (8 - 25) ÷(6.1)

= -2.79

Now the probability is

= P(Z<-2.79)

= 0.0026
