Answer:
<em>k=2/3</em>
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form <em>y/x = k or y = kx</em>
In this problem we have <em>3y = 2x</em>
Isolate the variable y
Divide by 3 both sides
<em>y = 2/3x</em>
Remember that
In a proportional relationship the constant of proportionality k is equal to the slope m of the line
The slope of the line m is
<em>m = 2/3</em>
therefore
The constant of proportionality k is
<em>k = 2/3</em>

Answer: -3x+1 and y column will have the same answers because y = -3x+1
<u>-3x+1</u>
-3(-2)+1 = 6+1 = 7
-3(-1)+1 = 3+1 = 4
-3(0)+1 = 0+1 = 1
-3(1)+1 = -3+1 = -2
-3(2)+1 = -6+1 = -5
<u>(x, y)</u>
(-2, 7)
(-1, 4)
(0, 1)
(1, -2)
(2, -5)

Answer:
1107
Step-by-step explanation:
72+ (33+12)23
= 72 + (45)23
=72+ 1035
=1107
Answer: $21.12
Step-by-step explanation:
From the question, we are informed that Paul bought 12.8 pounds of apples at the farmer’s market and that each pound of apples cost $1.65.
To calculate the total cost of the apples, we use the multiplication operation. This will be done by multiplying the pounds of apple bought by the cost of each pound. This will be:
= 12.8 × $1.65
= $21.12
Answer:
C - 10
Step-by-step explanation:
n is the number of the term
an = -2n+8
a9 = -2*9 +8
a9 = -18+8
a9 = -10
The 9th term is -10
