The line y=−0.5x+b passes through the points​ (1,5.5), (3,p),​ (4,4), and​ (7,n). Find​ b, n, and p.

Answers

Answer:   b = 6; n = 2.5; p = 4.5

Step-by-step explanation:

Finding b

If we use the given slope and use one of the points to write the equation in point-slope form (y - y₁) = m(x - x₁)), we can rearrange it to find the y-intercept:

Using (4,4)  

                                ⇒  y - 4 =  - 0.5 (x - 4)

                                     y - 4 = - 0.5 x + 2

                                          y = -0.5 x + 6

        ∴ b = 6

Calculating 'n' and 'p'

We can find n and p by plugging the points into the newly found equation   y = -0.5 x + 6.

For n using (7, n)

             since  y = -0.5 x + 6

                        n = -0.5 (7) + 6

                ∴        n = 2.5

For p using (3,p)

               since y = -0.5 x + 6

                         p = - 0.5 (3) + 6

                         p = - 1.5 + 6

                     p = 4.5

Checking the answer

We can check the answer we got in two ways:

We could also have found n a different way:

         Using the points (4, 4) and (7, n) as (x₁, y₁) & (x₂, y₂)   respectively

         The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)  

                               - 0.5  =  (n - 4) ÷ (7 - 4)

                               - 0.5 =  ⁿ⁻⁴/₃          [multiply both sides by 3]

                                - 1.5 = n - 4           [add four to both sides]

                                    n = 2.5     [this matches the value of n we found]

We can plot the line and see if it goes through the points we found. As seen in the graph below, the line passes through all the points.

If a rhombus is inside a regular hexagon, what is the size of x

Answers

Answer: x = 60°

Step-by-step explanation:

The rest of the question is the attached figure.

Given: A rhombus inside a regular hexagon, work out the angle x.

As shown

ABCDEF is a regular hexagon.

The regular hexagon have 6 congruent angles, and the sum of the interior angles is 720°

So, the measure of one angle of the regular hexagon = 720/6 = 120°

So, ∠F = ∠BAF = 120°

AFEG is a rhombus.

The rhombus have 2 obtuse angles and 2 acute angles.

∠F is one of the obtuse angles of the rhombus = 120°

∠F and ∠FA G are supplementary angles

So, ∠F + ∠FA G = 180°

∴ ∠FA G = 180° - ∠F = 180 - 120 = 60°

∴ x = ∠GAB = ∠BAF - ∠FA G = 120 - 60 = 60°

So, the measure of the angle x = 60°

You ask your best friend to lend you $300 to buy your favourite toy. She says she can lend you the money only if you give her an extra $3 for every three months that pass before you return it. What is the total amount you must pay her if you return it after nine months?

Answers

The answer is $309

Since its $3 extra per 3 months and 9 months pass it has to be an extra $9 for the $9 months.You already had to pay back the 300 so the equation would be (300+9=309)

5 + 0 + 9 + 9 + 4 = 27

8 + 8 + 0 + 0 + 7 = 23

4 + 1 + 9 + 5 + 7 = 26

6 + 5 + 8 + 3 + 6 = 28

1 + 9 + 7 + 9 + 9 = 35

Answers

36%

10 shares at 15 each is 150$ that it costed you to buy. You sold it for 210$ so you gained 54$ (60$ minus the 6$ commission).

Set up a proportion: 150/100 = 210/x. x=136% or your investment returned you 36% of your initial 150.

Answer:

y = 1.5x + 9  

(y = height; x = number of cups)

Step-by-step explanation:

let x = number of cups

let y = height of the stack

the first cup will add 9 to the height (7.5 + 1.5)

so 9 is the y-intercept

for each additional cup, 1.5 will be added

so y = 1.5x + 9

#7. let x = the amount of money he borrows each day. so, the equation would be 8x (because it’s over 8 days, so 8 times x) = 28

so equation: 8x=28
then solve for x, which is 3.5 so $3.50
