Square roots • square roots are the of perfect squares. • a square root of a number is one of its two equal factors. (remember • 4 · 4 = 16, so 4 is the of 16. 16 = 4 the symbol ,called a is used to show a number’s square root. examples: √4 = 2 because √9 = 3 because √16 = 4 because √25 = 5 because √100 = 10 × = × = × = × = × = find each square root. times itself gives you 81? (? · ? = 81) 81 196 49 225 121 16 4 36 64

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
