Harman [31]3 years ago

Answer:

C, y = 3x - 1

Step-by-step explanation:

the function's <em>y-values</em> increase by 3 at each interval. (rise)

the function's <em>x-values</em> increase by 1 at each interval. (run)

\frac{rise}{run} = \frac{3}{1}

the <em>slope </em>is 3

but, you still have to find the <em>y-intercept</em>

<em />b=y-mx<em />

<em>with</em><em> b </em><em>representing the</em><em> y-intercept </em><em>and </em><em>m </em><em>representing the</em><em> slope </em><em>of the line</em>

<em>and </em><em>x</em><em> and </em><em>y</em><em> are the </em><em>values</em><em> from a point on the table: (-2,-7).</em>

<em />b=-7-(3)(-2)<em />

<em />b=-7+6<em />

<em />b=-1<em />

<em>Therefore the equation of the line is </em>y = 3x -1<em />

A farmer wants to build a fence enclosing a rectangular region bordering a river. If the farmer has 500 feet of fencing, find th
Romashka [77]

Answer:

31,250 ft²

Step-by-step explanation:

Let x represent the length of fence parallel to the river. Then the ends of the rectangle will have dimesion (500-x)/2, and the total area will be ...

... A = x(500-x)/2

This function describes a parabola with zeros at x=0 and x=500. The vertex (maximum) will be located halfway between these, at x=250.

The maximum size pen has area ...

... A = 250(500 -250)/2 = 31,250 . . . . sq ft

Aveeno and her boyfriend you know who wrote the bus six times in a month it cost $40 for the two of them each time if Avena alwa
MaRussiya [10]

Answer: The cost for the month is $240.

Step-by-step explanation:

Since we have given that

Cost for the two i.e Aveeno and her boyfriend = $40

They were charged 6 times in a month.

As we know that times stands for multiplication.

So, we need to find the cost for the month, where we multiply 6 with $40 to get the amount for the whole month.

So, the amount for the month would be

40\times 6=\$240

Hence, the cost for the month is $240.
