Answer:

a=-27

Step-by-step explanation:

$\frac{a}{3} +(-84)=-93\\\\\frac{a}{3}+(-84)-(-84)=-93-(-84)\\\\\frac{a}{3}+0=-93+84\\\\\frac{a}{3}=-9\\\\3(\frac{a}{3})=3(-9)\\\\a=-27$

<h3>Answer: C) 5/2</h3>

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

Explanation:

The term "zero" is the same as "root".

The root of f(x) is found by replacing f(x) with 0 and solving for x.

f(x) = 4x-20

0 = 4x-20

0+20 = 4x

20 = 4x

4x = 20

x = 20/4

x = 5

The root of f(x) is 5. If you plugged in x = 5, then you'll land on f(5) = 0.

Your teacher then wants to know what value of k will have g(x) get the same root of 5. In other words, we need to find k that will allow g(5) = 0.

We'll replace g(x) with 0 and plug in x = 5. Solving for k leads to...

g(x) = -0.5x+k

0 = -0.5*5+k

0 = -2.5+k

0+2.5 = k

2.5 = k

k = 2.5

k = 5/2

andre [41]

Answer:

342.

Step-by-step explanation:

Let x represent the number of adults and y represent the number of senior citizens.

We have been given that on a recent weekend evening 514 people paid for the admission. We can represent this information in an equation as:

$x+y=514...(1)$

We have been given that the Family Fine Arts Center charges $20 per adult and $13 per senior citizen for its performances.

The cost of x adult tickets would be $20x$ and cost of y senior citizen tickets would be $13y$ .

We are also told that total receipts were $7886 on a recent weekend evening. We can represent this information in an equation as:

$20x+13y=7,886...(2)$

From equation (1), we will get:

We can represent this information in an equation as:

$x=514-y$

Substitute this value in equation (2) as:

$20(514-y)+13y=7,886$

$10,280-20y+13y=7,886$

$10,280-7y=7,886$

$10,280-10,280-7y=7,886-10,280$

$-7y=-2394$

$\frac{-7y}{-7}=\frac{-2394}{-7}$

$y=342$

Therefore, 342 senior citizens paid for the art center.

How is slope determined from this graph? Describe exactly how to determine the slope.

Sphinxa [80]

Answer:

Find two points on a graph, and count up/down, and left/right to find rise over run and simplify if you can. For example on this graph the slope from (0,1) to (3,0) is -2/6 or simplify to -1/3 because you go down two and right 6.

Bumek [7]

Answer:

84,3 ° Sureste

Step-by-step explanation:

El diagrama vectorial que tipifica la pregunta se muestra en la imagen adjunta.

La dirección del avión es la dirección de la velocidad resultante.

Si esta dirección es θ

θ = tan ^ -1 (400/40)

θ = 84,3 ° Sureste
