Answer: x = 3, y = 6

Solution:

4x - 3y = -6
2x + y = 12
Rearrange the terms

4x - 3y = -6
y = 12 - 2x
Substitute

4x - 3(12 - 2x) = -6
Solve the equation

x = 3
Substitute

y = 12 - 2 x 3
Solve the equation

y = 6
Write the solution

x = 3
y = 6

If the Internet consisted of four computers, there would be six possible connections. If it consisted of five computers, there w
Luba_88 [7]

Answer:

<em>45 possible connections</em>

<em />

Step-by-step explanation:

The general equation for finding the possible number of connections in a network is given as

\frac{n*(n - 1)}{2}

where n is the number of computers on the network.

for 4 computers, we'll have

\frac{4*(4 - 1)}{2} = \frac{4*3}{2} = 6

for 5 computers, we'll have

\frac{5*(5 - 1)}{2} = \frac{5*4}{2} = 10.

therefore, for 10 computers, we will have

\frac{10*(10 - 1)}{2} = \frac{10*9}{2} = <em>45 possible connections</em>

David has been tasked with tracking the number of bagels sold (y) at freddy's 24-hour bagel shop from 12: 00 am (*= 0) to 12: 00
mafiozo [28]

Answer:

53 bagels

Step-by-step explanation:

The number of bagels, y sold is a function of the square of the time (x) plus 4.

Therefore:

y=x^2+4

Number of Hours from 12.00 am to 7:00 am =7

At x=7

The number of bagels sold,

y=7^2+4\\=49+4\\=53\\

The bagel shop sold 53 bagels from 12: 00 am to 7: 00 am.
