Step-by-step explanation:
When you take a square root of a number, you get a positive and negative number
The principal square root is the positive number
4/8 is close to 1/2 and 3/7 is also close to 1/2
2.75 is rounded up to 3, and 1.25 is rounded down to 1. This means the expression would be 3x1.
Hope this helps.
Ik my hand writing is sloppy but the answer should be 60 if I’m not mistaken
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (-3, 1) and (2, -4). Substitute:
Therefore we have the equation of a line
Put the coordinates of the point (-3, 1) to the equation:
<em>subtract 3 from both sides</em>
<h3>Answer: y = -x - 2</h3>
