Domain (x-values)

Range (y-values)

Since they gave you the domain/x-values = -2, 1, 6, you can find the corresponding range/y-values by plugging in these values for "x" in the function:

x = -2

5x + y = 1 Substitute/plug in -2 into "x" to find the value of y

5(-2) + y = 1

-10 + y = 1 Add 10 on both sides to get "y" by itself

y = 11

x = 1

5x + y = 1 Plug in 1 into "x"

5(1) + y = 1 Subtract 5 on both sides

y = -4

x = 6

5x + y = 1

y = -29

Your answer is D

Answer:

5x - 4 = 11

Step-by-step explanation:

4 less than 5 times a number equals 11

5 times a number minus 4 equals 11

(5*x) - 4 = 11

I hope this helps!!!

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 500 peopl

konstantin123 [22]

Answer: In first question, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

In second question, The goal of $3050 fell by $710

Step-by-step explanation:

1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.

And, all 500 seats are filled for a performance.

Therefore, s + d = 500 ------(1)

Also, the price of one adult's ticket = $8.50

The price of one student's ticket= $5.50

And, their is a revenue of $3050 by selling the tickets.

Thus, 8.50 d + 5.50 s = 3050 --------(2)

By solving the equation (1) and equation (2),

we get, s = 400, d=100

Thus, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

2. According to the question,

s = 2 d ----- (3)

s + d = 360 -----(4)

By solving equation (3) and (4),

We get, s = 240 and d = 120

thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340

But, the goal is $3050 ( according to the question)

Thus the total fall = 3050 - 2340 = $710

1) Create was we already know in the equation. 16=-7(-3)+b. (This is using the initial equation of y=mx+b.)

2) Simplify and solve for b: 16=21+b = -5=b

3) Replug your be value into your equation: y=-7x-5.

Answer

y=-7x-5

Words: y equals negative seven x, minus five.

The endpoints of GH are G(3,3) and H(-7,7). Find the coordinates of the midpoint M.

sesenic [268]

Step-by-step explanation:

Hey there!!

You can simply use midpoint formulae to find midpoint of the coordinates.

Here, Given that;

G(3,3) and H(-7,7).

Using midpoint formulae,

$midpoint \: of \: gh = (\frac{x1 + x2}{2} ,\frac{y1 + y2}{2}$ )

$midpoint \: of \: gh = (\frac{3 - 7}{2} ,\frac{3 + 7}{2}$ )

After simplifying it we get,

= (-2,5).

Therefore, midpoint of GH is M(-2,5).

Hope it helps....
