Một hộp có 100 tấm thẻ như nhau ghi các số từ 1 đến 100 rút ngẫu nhiên hai thẻ rồi đặt theo thứ tự từ trái qua phải tính xác suất để rút ngẫu nhiên hai thẻ lập nên một số có hai chữ số

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
