You solve that inequality by replacing p with a number that would be greater than 9 when added to 6
An example is 7+6>9

P+6>9
-6 -6
p>3
P could be any number greater than 3.

A parachutist's speed during a free fall reaches 180 kilometers per hour. What is this speed in meters per second? At this speed

Darya [45]

Answer:

Speed of the parachutist is meters per second $2.083$ meter per second

Distance travelled in 2 seconds $4.167$ meter

Step-by-step explanation:

Speed of the parachutist is kilometers per hour = 180

Speed of the parachutist is meters per second $\frac{180*1000}{24*60*60} = 2.083$ meter per second

Distance travelled in 2 seconds $2.083 *2 = 4.167$ meter

For the rational expression 2x^2-7x-15/x^2-25, do both of the following,

Mrrafil [7]

Answer:

a. $\frac{2x + 3}{x+5}$

b. x ≠ -5 (Vertical asymptote) and x ≠ 5 (Hole)

Step-by-step explanation:

Factor the numerator (Grouping):

$2x^2 - 7x - 15$

Two numbers that multiply to -30 and add to -7 = -3 and 10

$[2x^2 - 10x] + [3x - 15]$

$(2x + 3)(x - 5)$

Factor the denominator (Difference of Two Squares):

$x^2 - 25$ = $(x +5)(x-5)$

Factored Expression:

(x - 5) can be factored out of top and bottom as a hole-

$\frac{(2x + 3)(x - 5)}{(x + 5)(x - 5)} = \frac{2x + 3}{x+5}$

Variable Restrictions:

Denominator ≠ 0

$x + 5 = 0\\x = -5$

Vertical asymptote at x = -5 ⇒ x ≠ -5

Pamela is 6 years younger than Jiri. The sum of their ages is 78 . What is Jiri's age?

Alona [7]

Let’s make

P = Pamela
J = Jiri

J - 6 = P

P + J = 78

We can replace P with J - 6 because they are the same thing.

J - 6 + J = 78

2J - 6 = 78

2J = 84

J = 42

Jiri is 42 years old.
