Choose the equation that represents a line that passes through points (-1, 2) and (3, 1).
oksian1 [2.3K]

Answer:

<h2>B. x + 4y = 7</h2>

Step-by-step explanation:

\text{The point-slope form of an equation of a line:}\\\\y-y_1=m(x-x_1)\\\\m-slope\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\==============================

\text{We have the points (-1, 2) and (3, 1). Substitute:}\\\\m=\dfrac{1-2}{3-(-1)}=\dfrac{-1}{4}=-\dfrac{1}{4}\\\\\text{Put the value of a slope and the coordinates of the point (3, 1) }\\\text{to the equation of a line:}\\\\y-1=-\dfrac{1}{4}(x-3)\\\\\text{Convert to the standard form}\ Ax+By=C:\\\\y-1=-\dfrac{1}{4}(x-3)\qquad\text{multiply both sides by 4}\\\\4y-4=-(x-3)\\\\4y-4=-x-(-3)\qquad\text{add x to both sides}\\\\x+4y-4=3\qquad\text{add 4 to both sides}\\\\x+4y=7

Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if
nirvana33 [79]

Let, x be the maximum hours he can rent skate board and helmet.

So, total price :

T = 4x + 6x

Now, it is given that he has only $30.

Therefore,

Total price should be less than or equal to $30.

4x + 6x ≤ 30

10x ≤ 30

x ≤ 3

Therefore, the maximum number of hours he can rent the skateboard is 3 hours.

Hence, this is the required solution.

What percent of 1/4 is 2/3 and what percent of 1/6 is 2/3 ?
vlada-n [284]

Answer:

The percentages are 267% and 400% respectively.

Step-by-step explanation:

To find the answers of these, you need to divide the second number by the first. This will give you the percentage.

2/3 ÷ 1/4 = 8/3 = 2.67 = 267%

You can do the same for the second one.

2/3 ÷ 1/6 = 12/3 = 4 = 400%
