Find the value of 715×211 although these numbers aren't quite as nice as the ones from the example, the procedure is the same, so the difficulty is the same same excepting the ability to perform the calculation in your head. you may choose to use a calculator.

Who knows what procedure the question is referring to... You can take advantage of the distributive property of multiplication to compute the product:

715 * 211 = 715 * (200 + 10 + 1) = 715 * 200 + 715 * 10 + 715 * 1

Computing the remaining products is trivial.

715 * 200 = 2 * 715 * 100 = 1430 * 100 = 143,000

715 * 10 = 7150

715 * 1 = 715

Then

715 * 211 = 143,000 + 7150 + 715 = 150,865

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?
