slope intercept form is y=mx+b where m is the slope and b is the y intercept
given that the slope is -2/3 and the y intercept is 4
m=-2/3 and b=4
is the equation
Answer:
One 8x10 photo costs $1.50.
Step-by-step explanation:
You can write two equations and use a system of equations.
Let w = price of 1 wallet-size photo.
Let n = price of 1 of 8x10 photo.
Basic package:
24w + n = 19.5
Deluxe package:
32w + 3n = 28.5
We have a system of equations:
24w + n = 19.5
32w + 3n = 28.5
Multiply both sides of the first equation by -3.
Rewrite the second equation below it and add the equations.
-72w - 3w = -58.5
(+) 32w + 3n = 28.5
---------------------------------
-40w = -30
w = -30 / -40
w = 0.75
24w + n = 19.5
24(0.75) + n = 19.5
18 + n = 19.5
n = 1.5
Answer: One 8x10 photo costs $1.50.
The equivalent fraction is 7/10.
<span>Si el agricultor da 1/4 y 1/8 de su granja, básicamente está regalando 3/8 de su granja si los agrega. Si su granja es una, u 8/8, y resta eso de la cantidad que se necesita, eso es 5/8 de su granja porque 8 / 8-3 / 8 = 5/8. Entonces el granjero todavía posee 5/8 de su granja.</span>
