Apply the distributive property to create an equivalent expression.
−9⋅(5j+k)=

Multiply the number outside the parenthesis by each term inside the parenthesis:

-9 * 5j = -45j

-9 *k = -9k

−9⋅(5j+k) = -45j - 9k

.

Step-by-step explanation:

The given expression is

We need to find the equivalent expression of given expression.

According to the distributive property,

Using distributive property the given expression can be rewritten as

Therefore, the required expression is .

v,jhvljh,b.b; hk; ljujb,vuvccklokll; k,m,km,

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
