We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.

How to work out 5-[5+8÷4-1]
rodikova [14]

PEMDAS (order of operations rules) require that we perform operations in a certain order: anything inside parentheses first, followed by any exponentiation, followed by mult. and div., finally followed by addition and subtraction.

Thus, we must evaluate 5+8÷4-1 first, as it's inside parentheses. Focusing on the division first, we get 5+8÷4-1 = 5 + 2 - 1, or 6.

Then we have 5 - [6], which comes out to -1.

(d) The student is enrolled in mathematics or English.=\frac{110+205-50}{450} =0.589\\

(e) The student is enrolled in English but not in mathematics.

=\frac{205-50}{450} =0.344\\

(f) The student is not enrolled in English or is enrolled in mathematics.

=\frac{450-205+110}{450} =0.7889\\
