Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 3)

Point (1, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{5-3}{1-0}$
[Slope] Subtract: $\displaystyle m=\frac{2}{1}$
[Slope] Divide: $\displaystyle m=2$

-3 +3(n+8)= 2(1 + 6n) - 8

lilavasa [31]

Answer:

3 =n

Step-by-step explanation:

-3 +3(n+8)= 2(1 + 6n) - 8

Distribute

-3 +3n +24 = 2 +12n -8

Combine like terms

21+3n = 12n -6

Subtract 3n from each side

21+3n-3n = 12n-3n -6

21 = 9n -6

Add 6 to each side

21+6 = 9n-6+6

27 = 9n

Divide each side by 9

27/9 = 9n/9

27/9 =n

Divide the top and bottom by 3

3 =n

Find the exact solution of -x2 +7x + 5 = 0 by using the Quadratic Formula.

jonny [76]

Answer:

The answer to your question is:

x 1 = -0.65

x2 = 7.65

Step-by-step explanation:

Equation -x² + 7x + 5 = 0

a = -1

b = 7

c = 5

Quadratic formula x = -b ±√(b² -4ac) / 2a

x = - 7 ± √(7² -4(-1)(5) / 2(-1)

x = -7 ± √(49 + 20) / -2

x = -7 ± √69 / -2

x = - 7 ± 8.3 / -2

x1 = -7 + 8.3 / -2 x2 = -7 -8.3 / -2

x 1 = -0.65 x2 = 7.65
