What line is parallel to 2x+5y=6 that goes through (5,3)
Anna11 [10]

Answer:

4y = x - 17

Step-by-step explanation:

First off, in the equation given : 2x + 5y = 6 , make y the subject of the formula which will give y = \frac{-2x}{5} + \frac{6}{5}  which make the gradient, m, the coefficient of x = \frac{-2}{5}  . Since the line we're looking for is parallel to the one we were given, their respective gradients would be the same. (If they were perpendicular, the gradient of the new line would be a negative inverse of the given line)

Then you proceed to use the one-point formula : y - y₀ = m(x - x₀), where   y₀ = 3 and x₀ = 5 from the point it goes through (5, 3)

y - 3 = \frac{1}{4}(x - 5); y - 3 = \frac{x}{4} - \frac{5}{4};  y = \frac{x}{4} - \frac{5}{4} +3

y = \frac{x}{4} - \frac{17}{4};  y = \frac{x-17}{4}  ;   4y = x - 17

I will mark brainliest for answering this question.

The unit rate of speed is 52.5 miles per hour

<em><u>Solution:</u></em>

Given that On a trip to visit relatives you drive 1,115.625 miles over the course of 21  hours and 15 minutes

We know that, 1 hour = 60 minutes

21  hours and 15 minutes = 21 hours + (15/60) hours = 21 + 0.25 = 21.25 hours

So they drive 1115.625 miles in 21.25 hours

To find the unit rate of speed of your vehicle in miles per hour, divide the total miles by time taken

unit rate of speed means miles driven in 1 hour

\rightarrow \frac{1115.625}{21.25} = 52.5

So the unit rate of speed is 52.5 miles per hour

2/4+3/8. how do I calculate this
solniwko [45]
Well, 2/4 is equivalent to 4/8. So you can turn the 2/4 into 4/8 and then add 4/8 plus 3/8.

Segment AB with endpoints at A(2, 4) and B(2, 18) is partitioned by point P according to the ratio of 3:4. Find the coordinate o
natta225 [31]

Using proportions, it is found that the coordinates of point P are given as follows: (2,10).

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The segment is partitioned by point P according to the ratio of 3:4, hence:

P - A = \frac{3}{7}(B - A)

This proportion is applied for both coordinates, hence, for the x-coordinate:

x - 2 = \frac{3}{7}(2 - 2)

x - 2 = 0

x = 2.

For the y-coordinate:

y - 4 = \frac{3}{7}(18 - 4)

y - 4 = 6

y = 10.

Hence the coordinates are (2,10).
