Answer:

21\ \text{square units}

Step-by-step explanation:

The points are D(-3,5), E(-3,-2) and F(3,0).

Area of a triangle is given by

A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}

\Rightarrow A=\dfrac{-3(-2-0)+-3(0-5)+3(5-(-2))}{2}

\Rightarrow A=21\ \text{square units}

The area of the given triangle is 21\ \text{square units}.

While you're in the parking lot, you realize that both the lightbulbs and the light switches
Romashka [77]

Cost of Lightbulb = x

cost of switch is x-8


9x + 4(x-8) = 520.50

Use distributive property:

9x + 4x -32 = 520.50

Simplify:

13x -32 = 520.50

Add 32 to both sides:

13x = 552.50

Divide both sides by 13

X = 42.50


A lightbulb costs $42.50

A switch costs 42.50-8 = $34.50

Determine if the following event is mutually exclusive:
sp2606 [1]

Answer:

Ask yourself: "Can I roll a prime number and an odd number at the same time?"

Since the answer is "yes it is possible" (eg: rolling a 3), this means the two events are not mutually exclusive. Mutually exclusive events have nothing in common.

In terms of a venn diagram, mutually exclusive events have no overlapping shared region.Step-by-step explanation:
