A cell phone plan costs $200 to start. Then there is a $50 charge each month. Write an equation relating the cost, y, and then number of months, x.

Answers

Answer:

y = 200 + 50x

Step-by-step explanation:

y = cost

x = number of months

The cost is equal to the cost to open the plan plus the monthly fee times the number of months

y = 200 + 50x

Answer:

y = 200 + 50x

Step-by-step explanation:

the cost = the base cost plus the monthly charge ($50 per the number of months you pay it)

Hints:

Step 1: Use Sine law the the angle B.

a/Sin A=b/SinB=c/SinC

24/Sin61^=12/SinB (accross multiply)

SinB=12Sin61^/24

SinB=0.437309853 then convert to degree =25.9 degree( depends on question rounded how many decimal) Read the question it must notes there.

--> Angle C=180-61-25.9=93.1 degree.

Step 2: Use Cosine law to calculate.

c^2=a^2+b^2−2ab⋅cosC

c^2=24^2+12^2-2(24)(12)cos93.1

c^2=720-576(-0.054078812)

c^2=720+31.11494

c^2=751.1494

c=27.4

Answers

Answer:

x = 0, 51

Step-by-step explanation:

→First, you need to factor out the GCF (Greatest Common Factor), which is -0.03x, like so:

-0.03x (x - 51) = 0

→Remove the -0.03 by divide it by both sides:

x(x - 51) = 0

→Separate each, like so:

x = 0

x - 51 = 0

→Solve for x:

x - 51 = 0

x = 51

Your solutions are, 0 and 51.

Please see attached image for the graph

Step-by-step explanation:

To graph the elevation versus time, we start by plotting the first point at time zero (when the climb begins) when Zane is 20 meters below the edge (-20 meters). This corresponds to the point (0, -20).

One second later (1 in the horizontal axis), Zane has moved up 4 meters, now reaching -16 meters. This is the point (1, -16) on the graph.

One second later at time 2 seconds, he is another 4 meters up which corresponds to the point (2, -12) on the graph.

you can go on like this plotting more points on the graph.

Please see the attached image that illustrates this and shows the appropriate line that represents Zane's position versus time (pictured in red)

Determine the discriminant for the quadratic equation -3=x^2+4x+1. Based on the discriminant value, how many real number solutions does the equation have ? Discriminant value = b^2-4ac

Answers

Answer:

One real root (multiplicity 2).

Step-by-step explanation:

-3=x^2+4x+1

x^2 + 4x + 4 = 0

Discriminant = 4^2 - 4*1*4 = 0

There is one real root (multiplicity 2).

The equation has 1 real solution.

The quadratic function is given as:

[tex]-3=x^2+4x+1[/tex]

Add 3 to both sides of the equation

[tex]3-3=x^2+4x+1 + 3[/tex]

This gives

[tex]0=x^2+4x+4[/tex]

Rewrite the equation as:

[tex]x^2+4x+4 = 0[/tex]

A quadratic equation is represented as:

[tex]ax^2+bx+c = 0[/tex]

By comparison, we have:

[tex]a =1[/tex]

[tex]b =4[/tex]

[tex]c = 4[/tex]

The discriminant (d) is calculated as:

[tex]d =b^2 - 4ac[/tex]

So, we have:

[tex]d =4^2 - 4 \times 1 \times 4[/tex]

[tex]d =16 - 16[/tex]

Evaluate like terms

[tex]d = 0[/tex]

Given that the discriminant value is 0, it means that the equation has 1 real solution.

When six is subtracted from five times a number, the result is 9

Answers

You do 9=5y-6. And then solve for y. It’s is 3.

Given that, when six is subtracted from five times a number, the result is 9. The number is 3.

What is the number?

Given that, when six is subtracted from five times a number, the result is 9.

Let the number be y, such that;

(5 × y) - 6 = 9

Next, we solve for y

(5 × y) - 6 = 9

5y - 6 = 9

5y = 6 + 9

5y = 15

y = 15 / 5

y = 3

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4
