Write the equation of a line that is parallel to y = 1/2x - 4 and that passes through the point (9, -6)

Mathematics

mafiozo [28]3 years ago

Answer:

y = (1/2)x - 21/2

Step-by-step explanation:

since both lines are parallel, both have the slope 1/2.

Start with the equation y = mx + b, and find b, when m = 1/2, x = 9 and y = -6:

-6 = (1/2)(9) + b

Mult. all terms by 2 removes the fractional coefficient 1/2:

-12 = 9 + 2b.

Then -21 = 2b, and b = -10 1/2, or -21/2.

The equation of the line is y = (1/2)x - 21/2.

Solve the inequalities -150x ≥ − 2,400 and -336 ≥ − 21y.
astra-53 [7]
Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so

-150x<u>></u>-2400
divide both sides by -150
flip sign
<u />x<u><</u>16



-336<u>></u>-21y
divide both sides by -21
flip sign
16<u><</u>y

they seem to have the same solution

x=y<u>></u>16

The ratio of a model building's dimensions to the building's actual dimensions is 1/52. If the height of the model is 15 inches,
g100num [7]
Set this up as a proportion with the model stuff on top and actual building stuff on bottom.  \frac{1}{52} = \frac{15}{x}.  Cross multiply to get x = 780.  The actual building is 780 inches.  In feet that is 65.

You are wrapping a gift box that is 16 inches long, 7 inches wide, and 9 inches tall. Find the amount of wrapping paper you need
Svetach [21]

Answer:

638 in.²

Step-by-step explanation:

Assuming you need to cover just the surface area of the box with no overlaps, and the shape is a rectangular prism, then you need to find the surface area of a rectangular prism.

SA = PH + 2LW

where

P = perimeter of base = 2(L + W),

H = height of prism

L = length of base

W = width of base

SA = 2(16 + 7)(9) + 2(16)(7)

SA = 638

Matt is saving to buy a new motorcycle. If he deposits $70 at the end of each month in an account that pays an annual interest r
gladu [14]
P = $70,  p = 2.5% = 0.025
q = 1 + 0.025 / 12 = 1.002
Future value of a periodic deposit:
A = P · q · ( q^30 - 1 ) / ( q - 1 )
A = 70 · 1.002 · ( 1.002^30 - 1 ) / ( 1.002 - 1 )
A = $2,166
Answer:
He will have $2.166 in 30 months.
