coach Park's car averages 33 miles per gallon of gasoline how many gallons of gas does he need for the trip? justify you answer

sladkih [1.3K]

Since we don't know the length of the trip, we can't find an exact answer.

However, we can write an expression for it. First, we let, T, represent the total number of miles for the trip.

Now, just divide T by 33. So our expression is T/33.

If you know the total miles of the trip, just divide it by 33 and you will have the answer.

Write the equation of the line in slope-intercept that has passes through the points (2,-5) and (8, 13).

const2013 [10]

Answer:

The equation of the straight line in Slope- intercept form

y = 3 x - 11

Step-by-step explanation:

Explanation:-

Given points are (2,-5) and (8, 13)

The Slope of the line

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} } = \frac{13-(-5)}{8-2} = \frac{18}{6} =3$

Equation of the line having slope 'm' and given point

$y - y_{1} = m (x - x_{1} )$

(x₁ , y₁) = ( 2, -5 )

$y - (-5) = 3 (x - 2 )$

y + 5 = 3x - 6

The equation of the straight line in slope intercept form

y = m x + c

y = 3 x - 6-5

y = 3 x - 11

Final answer:-

The equation of the straight line in Slope- intercept form

y = 3 x - 11

How do I solve this?

Tju [1.3M]

Answer: A: 3x^2y^(3/2)

Step-by-step explanation:

This can be written as

(81*x^8*y^6)^(1/4)

Then multiply each exponent by (1/4):

81^(1/4)*x^(8(1/4))y^6(1/4))

81^(1/4) = 3

x^(8(1/4)) = x^2

y^6(1/4)) = y^(3/2)

The result: 3x^2y^(3/2)
