If 1 pair is sold for $129
67 pairs will be sold for 67*129
= $8643
Answer:
slope=-1/2
y intercept =-2
Step-by-step explanation:
what u have to do is get y on 1 side and 3x on the other, so take away 3x from both sides which leaves you with 6y = -3x -12. then divide both sides by 6 to get y on it's own so you have y= -1/2x -2. this formula is y=mx+c the m is always the slope and the c is always the y intercept
Answer:
72 cm
Step-by-step explanation:
It would be multiplied by 8 so the length would become 72 cm
This is an exponential equation with a starting value of 12000 and an increase of 15% each years.
The following are true:
C. Each year, it increases by 15%
E. The painting's value was 12,000 at the time is was sold.
Answer:
h = 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 2
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = M (h, 3 ) and (x₂, y₂ ) = N (- 2, - 9 )
m =
=
, then
= 2 ( multiply both sides by - 2 - h )
2(- 2 - h) = - 12 ( divide both sides by 2 )
- 2 - h = - 6 ( add 2 to both sides )
- h = - 4 ( multiply both sides by - 1 )
h = 4
