is the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
<u>Step-by-step explanation:</u>
Here we have , The cost of 2 pounds of potatoes is $3.78. We need to find the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x . Let's find out:
Cost is y & number of pounds of potatoes is x :
, where k is constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
⇒
⇒ 
⇒ 
⇒ 
⇒
Therefore, is the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
The value of c could be any odd integer because and odd integer subtracted by an even integer is an odd integer.
Answer:
I am pretty sure the answer is A
Step-by-step explanation:
Answer:
y = one-half x + three-fourths
Step-by-step explanation:
The 2-point form of the equation of a line can be used for starters.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (11/12 -19/20)/(1/3 -2/5)(x -2/5) +19/20 . . . . fill in given values
y = ((55 -57)/60)/((5 -6)/15)(x -8/20) +19/20 . . simplify a little
y = (-1/30)/(-2/30)(x -8/20) +19/20 . . . . . . . . . . and a little more ...
y = 1/2x -4/20 +19/20
y = 1/2x +15/20
y = 1/2x +3/4 . . . . line in slope-intercept form
Answer:
x = 15
Step-by-step explanation:
3x - 13 + 58 = 90
3x - 13 = 90 - 58
3x -13 = 32
3x = 32 + 13
x = 45/3
x = 15
