Use the discriminant to determine the number of real solutions to the equation,<br> 10n^2 = 10 - 8n
galben [10]

Answer:

2 real solutions

Step-by-step explanation:

Get all the terms to one side

10n^2 = 10 - 8n

10n^2 +8n -10 =0

ax^2 +bx+c =0

The discriminant is

b^2 -4ac

8^2 - 4(10)(-10)

64 +400

464

If the discriminant is greater than 0 we have 2 real solutions

I’m horrible at geometry, help please?
Korvikt [17]

Answer:

Longest side = 13 inches

Step-by-step explanation:

Perimeter of triangle =  30 inches

x + 4x - 8 + 2x +3    =  30

x + 4x + 2x - 8 + 3 = 30

                   7x - 5 = 30

                          7x = 30 + 5

                          7x = 35

                            x = 35/7

         x = 5

Longest side is the hypotenuse.

Longest side = 2x + 3 = 2*5 + 3 = 10 + 3 = 13 inches

Help please! 10 points!
NISA [10]

Let's assume

number of chairs =x

number of tables =y

we are given

Gavin builds furniture for a living. he Sells chairs for $45 and tables for $70 each

So, we can find objective function as

Z=45x+70y

now, we can find inequalities

A table requires 10 hours and $15 worth of supplies to make

so, total hours to make table =10y

amount spent on table =15y

It takes Gavin 4 hours and $10 worth of supplies to build each chair

so, total hours to make chair =4x

amount spent on chair =10x

total number of hours to make chair and table =4x+10y

Gavin wants to work for no more than 40 hours per week

so, we get

4x+10y\leq 40

spend no more than $80 on materials

so, we get

10x+15y\leq 80

so,

objective function:

Z=45x+70y

Constraints:

4x+10y\leq 40

10x+15y\leq 80
