Semenov [28]

Answer:

Yes He should stop for Gas

Step-by-step explanation:

Step one:

given data

total distance left=429.5miles

we want to find the amount of gallons the car will consume for 429.5 miles

we are told that for 33 miles traveled the car will consume 1 gallon of gas

hence for 429.5 miles the car will consume x gallons

cross multiply we have

x=429.5/33

x=13.0gallons

This shows that the tank will be empty for a 429.5 miles.

$\\ \sf\longmapsto x+5+x-5=80$

$\\ \sf\longmapsto 2x=80$

$\\ \sf\longmapsto x=40$

Angles are

180-80=100°
x+5=40+5=45°
x-5=40-5=35°

What is the equation of the line that is perpendicular to the given line and passes through the point (3, 0)?

olga2289 [7]

Step $1$

Find the slope of the given line

Let

$A(-3,2)\ B(2,-1)$

slope mAB is equal to

$mAB=\frac{(y2-y1)}{(x2-x1)} \\ \\ mAB=\frac{(-1-2)}{(2+3)} \\ \\ mAB=-\frac{3}{5}$

Step $2$

Find the slope of the line that is perpendicular to the given line

Let

CD ------> the line that is perpendicular to the given line

we know that

If two lines are perpendicular, then the product of their slopes is equal to $-1$

$mAB*mCD=-1\\ mAB=-\frac{3}{5} \\ mCD=-\frac{1}{mAB} \\ mCD=\frac{5}{3}$

Step $3$

Find the equation of the line with mCD and the point (3,0)

we know that

the equation of the line in the form point-slope is equal to

$y-y1=m(x-x1)\\\\ y-0=\frac{5}{3} *(x-3)\\\\ y=\frac{5}{3} x-5$

Multiply by $3$ both sides

$3y=5x-15$

$5x-3y=15$

therefore

the answer is

the equation of the line that is perpendicular to the given line is the equation $5x-3y=15$

Which of the following is the point-slope form of the line?

ryzh [129]

Answer:

Step-by-step explanation:

We can see that the slope is positive, which means that the x-term must be positive.

If you expand and simply both equations into the form y = mx + b, you will find that m is positive for A and negative for B, hence A is the correct answer.
