Determine whether the given ordered pair is a solution to the system of equations.

1 answer:

6 0

Answer: No

Solution:

Substitute the values of x & y into the first equation
6 -(-1) = 3
6 + 5 is NOT equal to 3
Therefore we can say this is not true
For this to be true, when substituting the values of x & y, the equation must be true for BOTH equations. Since it’s not true for the first equation it doesn’t matter if it’s true or not for the other equation.

I hope this helps!

The radius is 5 Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14

Vsevolod [243]

Answer:

A = 78.5 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know r =5 and pi = 3.14

A = 3.14 (5^2)

A = 3.14 (25)

A = 78.5 cm^2

The president of a computer company must decide whether to place the company's new laptop on the market now or wait another year

Elanso [62]

Answer:

The president should release the new laptop now

Step-by-step explanation:

The profit if the new laptop is released now and no competitive device enters the market = $120,409.00

The profit if the new laptop is released now and a competitive device enters the market = $29,698

The profit if the new laptop is released in a years time and no competitive device enters the market = $84,742.00

The loss if the new laptop is released in a years time and a competitive device enters the market = $59,396.00

The chance that a competitive device will enter the market = 22%

∴ The chance that a competitive device will not enter the market = 1 - 22% = 78%

The expected increase in profit the company can make, compared to next year, if the new laptop is released and no competitive device enters the market = ($120,409.00 - $84,742.00) × 78% = $27,820.26

The expected increase in profit the company can make, compared to next year, if the new laptop is released and a competitive device enters the market = ($29,698.00 - $59,396.00)×0.22 = ($6,533.56) loss

Therefore, to maximize the expected profit over the next year, the president should release the new laptop now to make an expected profit of $27,820.26 over the next year.

Log base2 log base 25

UkoKoshka [18]

I think it’s 5. Since logarithms are used to find the original value of a power. Therefore you reverse it and do square root of 25 which is +5 or -5

Where is the point of intersection? x − 2y + 2 = 3 and x − y = 3

sasho [114]

Answer:

Step-by-step explanation:

x -2y = 1

x - y = 3

x - 2y = 1

-x + y = -3

-y = -2

y = 2

x - 2 = 3

x = 5
