Answer: C

Step-by-step explanation: y = 2x + 1, x + 3y = 10 in these two equations you can put y = 2x + 1 in 3y in x + 3y = 10 so it would be x + 3(2x + 1) = 10,

x + 6x + 3 = 10, 7x = 7 so x = 1 and when we put the value of x in y = 2x + 1, it would be y = 2(1) + 1 so y = 3. difference would be 3 - 1 = 2 so it is C

Which of the following is equal to the rational expression when x -2 or -6?
kykrilka [37]

The given expression is

f(x) = \frac{3(x+2}{(x+2)(x+6)}

And since we have x+2 common in numerator and denominator, there is a hole at x+2=0, that is at x=-2

And a function is undefined when denominator is zero. And at x=-6, denominator become zero.

So, at x=-6, the function is undefined, or there is a vertical asymptote at x=-6 and hole at x=-2 .

\huge\bold{Given :}

Angle 1 = 40°

Angle 2 = x°

Angle 3 = ( x + 28 )°

\huge\bold{To\:find :}

The value of x.

\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}

{\boxed{\mathcal{\purple{The\:value\:of\: x \:is\:56 ° .\:}}}}✅

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}

We know that,

\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}

➪ ∠ 1 + ∠ 2 + ∠ 3 = 180°

➪ 40 + x° + x° + 28° = 180°

➪ 2x° + 68° = 180°

➪ 2x° = 180° - 68°

➪ x° = \frac{112° }{2}

➪ x° = 56°

\sf\red{Therefore, \:the\: value \:of \:x\: is \:56°.}

\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

∠ 1 + ∠ 2 + ∠ 3 = 180°

✒ 40° + 56° + 56° + 28° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.

\boxed{Hence\:verified.}

1) Use the Euclidean Algorithm to nd the greatest common divisor of 71407 and 2020. (Write down all of the steps, so that you ar
Olenka [21]

Answer:

Step-by-step explanation:

We have

71407 = 2000(35)+1407\\2000 = 1407+1(593)\\1407= 2(593) + 221\\593 = 2(221) = 151\\221=151+70\\151=2(70)+11\\70 = 6(11)+4\\11=2(4)+3\\4 = 3+1\\3 = 3(1)+0\\

So we find GCD = 1

2) By back substitution we get

71407 (543) - 19387(2000) =1

So x = 543 and y = -19387

Because we got 71407 (543) - 19387(2000) =1

y cannot be positive

y can only be negative
