3n+5=23

3n+5 - 5=23 - 5

3n = 18

3n/3 = 18/3

n = 6

Hi!

We need to isolate n on one side.

Subtract 5 from both sides.

3n + 5 - 5 = 23 - 5

3n = 18

Divide by 3 on both sides.

3n/3 = 18/3

n = 6

The answer is n = 6

Hope this helps! :)

If the discriminant is positive how many solutions are there

Answer:

$b^2-4ac>0$ yields 2 real roots

Step-by-step explanation:

To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.

• $b^2-4ac>0$ yields 2 real roots

• $b^2-4ac=0$ yields 1 real root

• [tx]b^2-4ac<0[/tex] yields no real roots

Example:

$4x^2-7x+2=0$ where a=4, b=-7, and c=2

$b^2-4ac=(-7)^2-4(4)(2)=49-32=17$ .

It has 2 real roots

Use the distance formula to find the distance, to the nearest tenth, from S(7, −1) to V(−1, 3).

Answer: 8.9 units (choice C)

Explanation:

We plug $(x_1,y_1) = (7,-1) \text{ and } (x_2,y_2) = (-1,3)\\\\$ into the distance formula to get the following

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(7-(-1))^2 + (-1-3)^2}\\\\d = \sqrt{(7+1)^2 + (-1-3)^2}\\\\d = \sqrt{(8)^2 + (-4)^2}\\\\d = \sqrt{64 + 16}\\\\d = \sqrt{80}\\\\d \approx 8.94427\\\\d \approx 8.9\\\\$
