can someone help please ?

Answer:

Step-by-step explanation:

Slope and y-intercept form of a line: y =mx + b

m -> Slope;     b -> y-intercept

y = (-1/5)x + 9

Slope = -1/5

y-intercept = 9

Answer:

[tex]y=3x-15[/tex]

Step-by-step explanation:

Slope intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope of the line ([tex]m[/tex])

When it comes to parallel lines, they will always have the same slope but different y-intercepts. The given equation is [tex]y=3x-5[/tex]. Because 3 is in the place of m, we know that the slope of the line is 3. Therefore, the slope of the line parallel to it will also be 3. So far, this is what our equation looks like:

[tex]y=3x+b[/tex]

2) Find the y-intercept ([tex]b[/tex])

To find the y-intercept, we plug the given point (4,-3) into the equation we currently have and solve for b.

[tex]y=3x+b\\-3=3(4)+b\\-3=12+b[/tex]

Subtract both sides by 12

[tex]-3-12=12+b-12\\-15=b[/tex]

Therefore the y-intercept of our line is -15. Plug -15 back into the original equation as b.

[tex]y=3x+(-15)\\y=3x-15[/tex]

Step-by-step explanation:

sin(63°) = x/22

x = 22sin(63°) ≅ 19.6 units

Answer:

because it is a decimal so it multiplies 100 by the decimal which is a smaller number, almost like how when you divide it becomes a smaller number.

Step-by-step explanation:

hope this helps:)

i'm not sure why that is, but the only thing i can assume is that either your calculator is broken somehow or you are accidentally typing in the wrong numbers.

you might also have forgotten to clear your calculator before attempting to put in 0.12 x 100.

i recommend using an online calculator for the time being if your calculator is faulty/having issues.

Tori's loss from the stock will be $28.29 and her rate of return will be -84.75%.

Since Tori bought one share of Macy's stock on Nov 1, 2016 for $33.38 and she sold it and the closing price for that day was $5.09, her loss will be;

= $5.09 - $33.38

= -$28.29

Her rate of return will be:

= -28.29/33.38 × 100

= -84.75%

Answer:

x = 12

Side length = [tex]2\sqrt{3}[/tex] in

Step-by-step explanation:

Area of the given hexagon = 6 × (Area of the triangular section)

Area of the triangular section = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                 = [tex]\frac{1}{2}(2)(\sqrt{3})^{\frac{x}{12}}(\sqrt{3})^{\frac{x}{6}}[/tex]

                                                 = [tex](\sqrt{3})^{\frac{x}{12}}[(\sqrt{3})^2]^{\frac{x}{12}}[/tex]

                                                 = [tex](\sqrt{3})^{\frac{x}{12}}(3)^{\frac{x}{12}}[/tex]

                                                 = [tex](3\sqrt{3})^{\frac{x}{12}}[/tex]

Now area of the given hexagon = [tex]6(3\sqrt{3})^{\frac{x}{12}}[/tex]

Since, area of the hexagon is = [tex]18\sqrt{3}[/tex] in²

[tex]6(3\sqrt{3})^{\frac{x}{12}}=18\sqrt{3}[/tex]

[tex](3\sqrt{3})^{\frac{x}{12}}=(3\sqrt{3})^1[/tex]

[tex]\frac{x}{12}=1[/tex]

x = 12

Therefore, side length = [tex]2(\sqrt{3})^{\frac{x}{12}}[/tex]

                                      = [tex](2\sqrt{3})^{\frac{12}{12}}[/tex]

                                      = [tex]2\sqrt{3}[/tex] in.

Answer:

  (x, y) = (-8.625, -63)

Step-by-step explanation:

Substitute for y.

  -63 = 8x +6

  -69 = 8x . . . . . subtract 6

  -69/8 = x = -8.625

The solution is (x, y) = (-8.625, -63).

Answer:

Siti's money = RM 430

David = RM 1,290

Farid = RM 280

Step-by-step explanation:

Let

Siti's money = x

David = 3x

Farid = x - 150

Total of their money = RM 2 000

x + 3x + (x - 150) = 2000

4x + x - 150 = 2000

5x = 2000 + 150

5x = 2,150

x = 2,150/5

x = RM 430

Siti's money = x

= RM 430

David = 3x

= 3(430)

= RM 1,290

Farid = x - 150

= 430 - 150

= RM 280

Answer:

Step-by-step explanation:

Answer:

Y= 3b

Step-by-step explanation:

Answer:

A=80

B=31

C=64

Step-by-step explanation:

A, 69, and b will equal 180 since it forms a straight line

A+69+b=180

to solve for A we subtract 53+47 from 180 and get 80

80+69+b=180

to get B we subtract 80+69 from 180 and get 31

to get c we add 85+b and subtract it from 180 getting c=64

Answer:

Hey it's me again the life saver ;)

To find b we can use the linear pair property but since only 1 angle is given, we owuld need at least 2 angles on this situation to find b so, to do that we are first going to find a

a=>

53 + 47 + a = 180

a=180 - 100

a=80°

Now to find b=>

80 + 69 + b =180 (Because of Linear pair property)

b = 180-149

b=31°

Now that we have got b, to solve c, we can again use the sum of all angles in a triangle are 180°

c=>

31 + 85 + c =180

c=180 - 116

c=64
