Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that [tex]m[/tex] represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for [tex]m[/tex] months =  $25[tex]m[/tex]

Total cost of the phone = Initial payment + Charges paid for [tex]m[/tex] months

[tex]C = 25m + 50[/tex]

It is a linear equation between two variables [tex]C[/tex] and [tex]m[/tex].

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

[tex]y=Mx+c[/tex]

[tex]M[/tex] is the slope.

On Comparing, we get:

[tex]y = C, M = 25, x = m, c = 50[/tex]

Therefore, the slope is 25.

Answer:

Y = mx + b

Y = 22x + 190

M is the slope

Y is the y intercept

Answer:

16 might be correct but don't quote me on this...

Step-by-step explanation:

104-88=16

let me know if this is correct, Thanks! :-)

Answer:

C

Step-by-step explanation:

We can use the Pythagorean theorem [ a² + b² = c² ] to solve for the missing side length.

88² + b² = 104²

7744 + b² = 10816

b² = 3072

√b = √3072

b ≈ 55.43

Best of Luck!

Answer:

  y = -1/3x +(7 2/3)

Step-by-step explanation:

The 2-point form is a good place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (6 -8)/(5 -(-1))(x -(-1)) +8

  y = -2/6(x +1) +8

  y = -1/3x +(7 2/3)

Answer:

x=2 y=-1

Answer:

The probability that she takes out a red marble the first time and a green marble the second

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                [tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Step-by-step explanation:

Step(i):-

Given a bag of marbles contains 5 red marbles, 5 green marbles, 5 yellow marbles and 5 blue marbles

Total balls n(S) = 5red +5green +5yellow + 5blue  =  20

Total numbers cases

                         n(S) = 20C₁ = 20 ways

Step(ii):-

Let E₁ be the event of drawing one red marble from 5 red balls

                       n(E₁) = 5C₁

Let E₂ be the event of drawing one green marble from 5 green balls

                       n(E₂) = 5C₁

The two events are independent events

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                =[tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Final answer:-

 The probability that she takes out a red marble the first time and a green marble the second

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                =[tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Answer:

24

Step-by-step explanation:

Answer:

x = 2.5m/s.

Step-by-step explanation:

Given that F = 0.5 + 0.004(x + 50)(x – 2.5), where x is the speed in m/s and F is the force in N. To know the speed, x, with F = 0.5N, we have:

0.5 = 0.5 + 0.004(x + 50)(x – 2.5)

This gives

0.004(x + 50)(x – 2.5) = 0 (after adding –0.5 to both sides).

For the multiplication to be 0, (x + 50)(x – 2.5) = 0 because 0.004 is not equal to 0.

Hence

x = –50 or x = 2.5

Since it is said from the question that x is positive then x = 2.5m/s.

Answer: Look below.

y = 3x + 12

Answer:

H

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 )

Given

3x + 2y = 19 ( subtract 3x from both sides )

2y = - 3x + 19 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{19}{2}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{3}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex] → H

Answer:

Step-by-step explanation:

its correct

Answer: It took 2 and a half hours for the repairs

Step-by-step explanation:

subtract 35 dollars from the total payed of 85 dollars you're left with 50 dollars we know the repairman charges and extra 20 dollars for every hour he's doing the repairs divide the 50 dollars more she had to pay and divide it by the 20 dollars he charges per every hour he's making repairs and you'll get 2.5 hours

The number of hours used for the repair is 2 1/2 hours.

Let the number of hours used for the repair be represented by h

Based on the information given, the equation to solve the question will be:

35 + (20 × h) = 85

35 + 20h = 85

Collect like terms

20h = 85 - 35

20h = 50

Divide both side by 20

20h/20 = 50/20

h = 2.5 hours

In conclusion, it took 2 1/2 hours for the repair.

Step-by-step explanation:

[tex]4y=8x+3[/tex]

To identify the slope of the line, the equation must be in the format [tex]y=mx+b[/tex], in which [tex]m[/tex] is representative of slope.

Begin by dividing both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]4[/tex]:

[tex]y=2x+\frac{3}{4}[/tex]

[tex]m=2[/tex]

Therefore, the slope of the line is 2.
