Answer:

The answer is the option b: b.

The explanation is shown below:

1. You have that S represents the number of tickets for the Spartans and V represents the number of tickets for the visiting team's fans, and the seating capacity of the Spartan Stadium is 30,000. Therefore, the total number of tickets is 30,0000:

2. If the Spartans get four times as many tickets as the visiting team, you have:

3. If you solve the system of equations by the method of substitution, you obtain:

4. Calculate S:

What value or values of x satisfy 2|x + 5.3| = 4.2? x can only equal –3.2. x can only equal 7.4. x can equal –3.2 or –7.4. x can equal –3.2 or 7.4.

2 | x + 5.3 | = 4.2

| x + 5.3 | = 4.2 / 2

| x + 5.3 | = 2.1

x + 5.3 = 2.1 x + 5.3 = - 2.1

x = 2.1 - 5.3 x = -2.1 - 5.3

x = - 3.2 x = - 7.4

solution is : x = -3.2 or x = -7.4

| x + 5.3 | = 4.2 / 2

| x + 5.3 | = 2.1

x + 5.3 = 2.1 x + 5.3 = - 2.1

x = 2.1 - 5.3 x = -2.1 - 5.3

x = - 3.2 x = - 7.4

solution is : x = -3.2 or x = -7.4

Answer:

What value or values of x satisfy 2|x + 5.3| = 4.2?

x can only equal –3.2.

x can only equal 7.4.

x can equal –3.2 or –7.4.

x can equal –3.2 or 7.4.

Step-by-step explanation:

x can equal –3.2 or –7.4. Is the correct answer.

A line passes through the point(-9,-5) and has a slope of 2/3 . write the equation for this line

Answer:

y = x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = , hence

y = x + c ← is the partial equation

to find c substitute (- 9, - 5) into the partial equation, that is

- 5 = - 6 + c ⇒ c = - 5 + 6 = 1

y = x + 1 ← equation of line

What is the value of 3x - 12y if x= - 2/9 And y= 4 1/6

3x-12y

x=-2/9

y=25/6

3(-2/9)-12(25/6)=-152/3=-50.666666....

x=-2/9

y=25/6

3(-2/9)-12(25/6)=-152/3=-50.666666....

47 1/3 I think. Hope I'm right

What is 2 thirds plus 3 fourths

2/3 + 3/4. To solve this equation sir you must find a common denominator. The lowest common denominator is 12. It will equal 17/12 or 1 and 5/10.

In order to find this you need to find a common denominator. 2/3 and 3/4 common denominator would be 12 and so what you do to the bottom you must do to the top. 2x4 is 8 and 3x3 is 9. that would make 8/12 and 9/12. 8 plus nine is 17 and 12 stays there so the answer is 17/12 which equals 1 and 5/10.

Is a triangle with the side lenths of 4mm, 11mm, 15mm a right triangle

The triangle with side lengths 4,11,15 does not even exist.

According to the Triangle Inequality Theorem, in order for the triangle to even exist, the sum of the two shorter lengths must be strictly greater than the length of the third side.

4 + 11 = 15.

15 is not greater than 15.

According to the Triangle Inequality Theorem, in order for the triangle to even exist, the sum of the two shorter lengths must be strictly greater than the length of the third side.

4 + 11 = 15.

15 is not greater than 15.

(1 point) Find f if F"(x) = sin 2 + cos x, f(0) = 10, and f(0) = 7.

Answer:

F(x)=sin(2)*-cos(x) +10x + 8

Step-by-step explanation:

in order to find F(x) you need to integrate two times.

-> First time

F'(x) = sin(2)*x + sin(x) + C,

if F'(0)=10 then F'(0)=sin(2)*(0) +sin(0) +c=10, so c=10.

Replacing C=10

F'(x) = sin(2)*x + sin(x) + 10.

-> Second time

F(x)=sin(2)*-cos(x) +10x +

if F(0) = 7 then sin(2)*0 - cos(0) + 10*0 +=7

so =8

Replacing this

F(x)=sin(2)*-cos(x) +10x + 8

If f(0)=10 and f'(0)=7 the answer is F(x)=sin(2)*-cos(x) +7x + 11

if F''(x)=sin(2x)+cos(x), f(0)=10, f'(0)=7 , the answer is F(x)=-sin(2x)/4 -cos(x) +15x/2+11

PLEASE HELP!! BRAINLIEST= 50 POINTS!!! This morning, some dragons, horses, and chickens were playing in my backyard. I counted 15 heads, 50 legs, and 4 wings. How many dragons, how many horses, and how many chickens were playing in my backyard?(For your information: any healthy dragon has three heads, four legs, and two wings. Feel free to use Wikipedia to obtain the information about the number of heads, legs, and wings of the rest of the creatures. Oh, and all creatures on my backyard were healthy.)

2 dragons

10 horses

5 chickens

10 horses

5 chickens

i got it!!

if all animals are healthy, then it would be:

-one dragon

-one chicken

-11 horses

hope this helps!!
