Answer:

1/3

Step-by-step explanation:

To simplify the fraction 7/21 in its simplest form, you first have to find the common factor between the two numbers, which in this case is seven. Next, divide the numerator and denominator by the factor. So...

7÷7=1

21÷7=3

Seven over twenty-one is the same as one-third, or one over three.

Subtract 7x^2−5xy+8y2 from −2x^2−15xy+9y^2

Digiron [165]

Answer

Subtract $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$

then;

$-2x^2 -15xy+9y^2 - (7x^2 -5xy+8y^2)$

Remove the bracket we have;

$-2x^2 -15xy+9y^2 - 7x^2 + 5xy - 8y^2$

Like terms are those terms which have same variable to the same power.

Combine like terms;

$-9x^2 -10xy+y^2$

Therefore, Subtracting $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$ we get $-9x^2 -10xy+y^2$

HELP!!!!! write the equation below the represents the line passing through the point (-3, -1) negative one with a slope of 4

omeli [17]

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-1})~\hspace{10em} slope = m\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-1)=4[x-(-3)] \\\\\\ y+1=4(x+3)\implies y+1=4x+12\implies y=4x+11$
