Hello from MrBillDoesMath!
Answer: y = 2x - 7
Discussion:
Divide both sides of the equation by 2:
2y /2 = (4x-14)/2 = 4x/2 -14/2
or
y = 2x - 7
Thank you,

The square will have area
.. (9 cm)^2 = 81 cm^2.
The two triangles together will have area
.. (9 cm)*(12 cm) = 108 cm^2.
The sum of the areas of those three shapes is
.. 81 cm^2 +108 cm^2 = 189 cm^2

Answer:
Step-by-step explanation:
Ruth's salary is s(j), where s represents salary and j the number of jars she sells.
At the very beginning, she receives $50. Only answer 'd' could be correct.
But also, the equation has the variable part 0.65j, or
$0.65j, which is directly proportional to the unit price of the jars of jelly.
*
Summing up the fixed and variable parts, we get
s = $50 + ($0.65j), or s = $50 + ($0.65/jar)j This is Answer D.
