Given the graph of a proportional relationship, if the (2,7) lies on the graph, what is the value of k? What is the equation of the line?
Answer:
k=3.5, and y=3.5x is the equation of the line
Step-by-step explanation:
y and x are proportional means that y = kx for some constant k.
Thus, when y=7 and x=2, we have that 7 = k * 2, so that k = 7/2 = 3.5,
and the equation of the line is y = 3.5x
Walmart sells 6 gel pens for $15.00 and 4 notebooks for $5.40. What is the

Answer:
$1.15
Step-by-step explanation:
$15 / 6 =$2.50 for each gel pen
$5.40 / 4= $1.35 for each note book
$2.50- $1.35= $1.15
in the similarity transformation of abc to def, abc was dilated by a scale factor of [?], reflected across the [ ], and moved through the translation [ ].
The complete similarity transformation is: triangle abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].
How to complete the similarity statement?From the figure, we have:
AB = 2 units
DE = 4 units
So, the scale factor (k) is:
k = DE/AB
k = 4/2
k = 2
So, the scale factor is 2
Also, both shapes are on either sides of the x-axis, and they are equidistant from the x-axis.
This means that the triangle is reflected across the x-axis with no translation.
Hence, the complete similarity transformation is:
abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].

Step-by-step explanation:
a patio furniture set sells for $935 on installment plan, which includes finance charge the payment plan calls for 15 percent down and the balance in 12 equal paymnets. the ampount of the payment is
The monthly payment for the patio furniture will be $66.23
Cost of the patio furniture = $935
Since there's a 15% down payment, then the amount that the buyer will pay will be:
= 15% × $935
= 0.15 × $935
= $140.25
Therefore, the amount that is left to pay will be:
= $935 - $140.25
= $794.75
Since the balance will be paid for 12 months, the monthly payment will be:
= $794.75 / 12
= $66.23

Answer: 13.1 minutes (approximate)Lori brought sunglasses and flip-flops at a half-off sale.If she spent a total of $21 on the two items, what was the original price of the sunglasses?
The sunglasses were originally priced at $ 21.
Given that Lori brought sunglasses and flip-flops at a half-off sale, to determine, if she spent a total of $ 21 on the two items, what was the original price of the sunglasses (taking into account that they both cost the same) will be you must perform the following calculation:
50 = 21 100 = X 100 x 21/50 = X 2100/50 = X 42 = X
