Correction:

Factor this expression.

x² + 9x + 8

Now,

x² + 9x + 8

By splitting middle term, we get:

x² + 8x - x + 8

take common

x ( x + 8 ) - 1 ( x + 8 )

( x + 8 ) ( x - 1 )

Find the two smallest possible solutions to part 1a

bixtya [17]

<h3>Answer: A. 5/12, 25/12</h3>

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

Work Shown:

12*sin(2pi/5*x)+10 = 16

12*sin(2pi/5*x) = 16-10

12*sin(2pi/5*x) = 6

sin(2pi/5*x) = 6/12

sin(2pi/5*x) = 0.5

2pi/5*x = arcsin(0.5)

2pi/5*x = pi/6+2pi*n or 2pi/5*x = 5pi/6+2pi*n

2/5*x = 1/6+2*n or 2/5*x = 5/6+2*n

x = (5/2)*(1/6+2*n) or x = (5/2)*(5/6+2*n)

x = 5/12+5n or x = 25/12+5n

these equations form the set of all solutions. The n is any integer.

--------

The two smallest positive solutions occur when n = 0, so,

x = 5/12+5n or x = 25/12+5n

x = 5/12+5*0 or x = 25/12+5*0

x = 5/12 or x = 25/12

--------

Plugging either x value into the expression 12*sin(2pi/5*x)+10 should yield 16, which would confirm the two answers.

A line passes through the point (-7,8) and has a slope of 1

Mila [183]

Answer:

y - 8 = x + 7

Step-by-step explanation:

To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

$y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7$
