Here are four digits.
Bogdan [553]

Answer:

A: 357

(1) 9641

Step-by-step explanation:

With A you really just want to go from the smallest number up so it would be the smallest number possible.

<em>EX.</em> 357 vs. 736   357 is smaller

With 1 you have to go from the highest number to lowest number to get the biggest answer possible.

<em>Ex.</em>  9641 vs. 1946    9641 is larger.

Which of the following is the equation of a line that passed though the points (2,5) and (4,3)
STatiana [176]

The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.

As we now know that the gradient is -1. We can simply put any one point in the equation y - y1 = m(x - x1) to get the line of equation. WHen we calculate the line of equation it come out to be y = -x + 7

Which expression represents the distance between the points (a, 0) and (0, 5) on a coordinate grid?
Mashcka [7]
 \displaystyle d= \sqrt{(x_1-x_0)^2+(y_1-y_0)^2} - d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.

In our case :
(x_1,y_1)=(a,0)\\(x_0,y_0)=(0,5)

d= \sqrt{(a-0)^2+(0-5)^2} = \sqrt{a^2+25}
