<em>-7 -5 / 4 -2 / -12/2 </em>

<em>-12/2 = -6 </em>

<em>Slope: -6x </em>

<em>5 = 2(-6) + b</em>

<em>5 = -12 + b </em>

<em>-12 + 17 = 5 </em>

<em>Slope intercept Form: y = -6x + 17</em>

Answer:

a). Mileage for carA= \frac{2}{x}  , and mileage for carB=\frac{ 3x+2}{x(x+1)}

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{5x+4}{2x(x+1)}[tex]mil/gal

Step-by-step explanation:

It is given that the distance traveled by car A=2x+2=2(x+1)

And distance traveled by car B= 3x+2

We know the mileage is mile/gallon,

a).So mileage of car A= \frac{distance traveled by car A}{gallos of fuel used}

=\frac{2x+2}{x^2 +x}\\ =\frac{2(x+1)}{x(x+1)} \\=\frac{2}{x}mil/gal

Similarly , the mileage for car B= \frac{distance traveled by car A}{gallons of fuel used}

=\frac{3x+2}{x^2+x} \\=\frac{3x+2}{x(x+1)}mil/gal

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{2x+2}{x(x+1)}+\frac{3x+2}{x(x+1)}\\ =\frac{2x+2+3x+2}{x(x+1)}\\=\frac{5x+4}{x(x+1)}mil/gal

Now divide by 2 for total(average) mileage.

\frac{\frac{5x+4}{x(x+1)} }{2}\\ =\frac{5x+4}{2x(x+1)} mil/gal.

Thus those are the answers.

Plz help which one is not a chord
kaheart [24]

Answer:

Line FN.

Step-by-step explanation:

A chord is a line whose endpoints both lie on the circle.

All the other lines' endpoints are on the circle.

In line FN, point N is on the circle but point F is not.

This makes line FN not a chord.

I not very good with slope and y intercept form. any tips ?
jeyben [28]

Step-by-step explanation:

To find the slope you use the slope formula which is y2-y2/x2-x1

And to find the y intercept you use y=mx +b. Yous substitute the slope as m and you substitute a point from the line to find b. Which is the y intercept

Which equation is modeled by the graph? Using the equation, about how many more cars are in the deck at 9:00 a.m. than at 8:30 a
omeli [17]
The correct answer is Choice A.

You can see from the graph that the y-intercept is 50 because it cross on the left at 50.

To find the slope, we can use the following two points (0, 50) and (20, 110). This will give a slope of 3.

Put the 50 and 3 together and you will have the equation:
y = 3x + 50
