Answer:

$x=-1$

Step-by-step explanation:

$9x+8=7x+6$

Keep the variables in the left side & rest in the left side:

$9x-7x=6-8$

$2x=-2$

$x=-2/2$

$x=-1$

Sebastian wants to create a right triangle with side lengths 14 inches, 48 inches, and 5

allochka39001 [22]

Answer: Choice A

$\text{Yes, because } 14^2+48^2 \text{ is equal to } 50^2$

=======================================================

Explanation:

The pythagorean theorem is $a^2+b^2 = c^2$

The value of c is always the longest side, aka hypotenuse.

The order of 'a' and b doesn't matter.

So a = 14, b = 48, c = 50

We have $a^2+b^2 = 14^2+48^2 = 196+2304 = 2500$

We also have $c^2 = 50^2 = 2500$

Both sides result in 2500 which proves that $14^2+48^2 = 50^2$ is a true statement. Therefore, we do have a right triangle.

An internet provider advertises that their average service rate is $73. Given that their service rates are $11, $84, $94, and $1

forsale [732]

Answer:

The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).

Step-by-step explanation:

The service rate was given as $11, $84, $94 and $103.

The average service rate = $\frac{sum of the service rate}{number of service rate}$

= $\frac{11 + 84 + 94 + 103}{4}$

= $\frac{292}{4}$

= 73

Their average service rate is $73.

But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).

If A= 3x^2+5x-6 and B = -2x^2-6x+7 then A-B equals

Ber [7]

Answer:

A-B=x^2-x+1

Step-by-step explanation:

A-B=3x^2+5x-6+(-2x^2-6x+7)

=3x^2+5x-6-2x^2-6x+7

=x^2-x+1

Francine and Genevieve were arguing about whether a recursive formula or an explicit formula was better to know to find the 376t

forsale [732]

Genevieve is correct. This is because if you only want to find a particular term of a sequence like in this word problem only the 376th term; the explicit definition will be more useful and quick. Recursive requires the previous numbers to find the next term and will take longer time to find the 376th term.
