K= 3/5 or -9 set each factor equal to zero and solve for x

Set the factors equal to 0.

(5k - 3)(9 + k) = 0

The zero product property states that if two terms being multiplied have a product of zero, then at least one of them must be zero. In our case, this means we can set both (5k - 3) and (9 + k) equal to 0:

5k - 3 = 0
5k = 3
k = 3/5

9 + k = 0
k = -9

The value of k is 3/5 and -9.

How can I graph 34+12d>100 on a number line?

marissa [1.9K]

Answer:

d> 5.5

The graph in the attached figure

Step-by-step explanation:

we have

$34+12d>100$

Solve the inequality for d

That means ---> isolate the variable d

Subtract 34 both sides

$12d>100-34\\12d> 66$

Divide by 12 both sides

$d>\frac{66}{12} \\d>5.5$

The solution is the interval (5.5,∞)

All real numbers greater than 5.5

In a number line the solution is the shaded area at right of d=5.5 (open circle)

The value of d=5.5 is not included in the solution
