A cell phone company charges $50 for the phone plus a monthly service charge of $30. An equation gives the cost y after x months. Which is the true of the relationship between x and y?

Answer

Input= 5

Output= 120

Step-by-step explanation:

The input goes up by 1, so m=5

The output shows how many hours there are in that many days so blank=120

Answer

output for m is 5

Step-by-step explanation

- multiply the input by a number to get the output

- to get the number to multiply it by you can divide a given out put by the input

( 24/2) = 12

- notice patterns

input- output

Answer:

i believe its 7 + x < 20

Step-by-step explanation:

The inequality function that represent the given statement should be 7 + x < 20. The second option is correct.

It is the relationship  type that shows the relationship with the graph.

Since the statement like

Seven more than a number, 2, is at most 20.

So its inequality function be like

7 + x < 20

hence, the second option is correct.

And, the rest of the options are incorrect.

Answer:

x = -6 & y= 42

Step-by-step explanation:

I hope this helps :)

x = 6, y = -42

Substitution:

-7x = -5x - 12

-2x = -12

x = 6

When x = 6,

y = -7(6) = -42

Answer: 7.26

Step-by-step explanation:

calculator

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

           4a2 - b2

Simplify   ————————

            2a - b  

Trying to factor as a Difference of Squares:

2.1      Factoring:  4a2 - b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  4  is the square of  2  

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (2a + b)  •  (2a - b)  

Canceling Out :

2.2    Cancel out  (2a - b)  which appears on both sides of the fraction line.

Final result :

 2a + b

Answer:

A. n

Step-by-step explanation:

n/4 + n/4 + n/4 + n/4 = 4n/4 = n

On solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.  Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the following expression -

n/4 + n/4 + n/4 + n/4

We can write -

n/4 + n/4 + n/4 + n/4

n/4(1 + 1 + 1 + 1)

4 x n/4

n

Therefore, on solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.
