Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.

Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.

Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>

Question is Incomplete; Complete question is given below;

Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.

What is Mr. Lin’s total payment, including tip?

Answer:

Mr. Lin made a Total payment of $460 including the Tip.

Step-by-step explanation:

Given:

Total bill = $400

Percentile amount paid in tip = 15%

We need to find the total payment, including tip.

Solution:

First we will find the amount paid in Tip.

amount paid in Tip can be calculated by Percentile amount paid in tip multiplied by Total bill and then divided 100.

amount paid in Tip = $\frac{15}{100}\times 400 = \$60$

Now we know that;

Total payment made by Mr.Lin is equal to sum of Total bill and amount paid in Tip.

framing in equation form we get;

Total payment made by Mr.Lin = $\$400+\$60 =\$460$

Hence Mr. Lin made a Total payment of $460 including the Tip.

What are the roots of the quadratic equation below 3x2+15x-5=0

fomenos

Answer:

Step-by-step explanation:

$3x^2+15x-5=0\\a = 3\\b = 15\\c = -5\\ x = -b\±\frac{\sqrt{b^{2} -4ac} }{2a} \\x = -(15)\±\frac{\sqrt{15^{2} -4(3)(-5)} }{2(3)} \\x = -15 \±\frac{\sqrt{225+60} }{6} \\x = -15\±\frac{\sqrt{285} }{6} = A$
