Express y=3x+2 in general form
katrin [286]

General form of a linear equation is ax+by+c=0 where a,b, and c are three real numbers.

So, we can shift all the terms in one side of the equation. Hence, first step is to remove y from the left side. So, subtract y from each sides.

y-y=3x+2-y

0= 3x - y +2 (By simplifying)

So, the general form of the given equation is 3x-y+2=0.

Please solve this. Thanks
svlad2 [7]

\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \parallel\ k\iff m_1=m_2\\\\\text{We have}\\\\L_1:y=5x+1\to m_1=5\\\\L_2:2y-10x-3=0\qquad\text{add 10x and 3 to both sides}\\\\L_2:2y=10x+3\qquad\text{divide both sides by 2}\\\\L_2:y=5x+1.5\to m_2=5\\\\m_1=m_2\ \text{therefore}\ l_1\ \text{and}\ L_2\ \text{are parallel.}

Calculate the surface area of this box.
julia-pushkina [17]

Answer:

36 cm^2

Step-by-step explanation:

S.A. = 2 (lw + wh + lh)

S.A. = 2 ((4)(2) + (2)(2) + (4)(2))

S.A. = 2 (8 + 4 + 6)

S.A. = 2 (18)

S.A. = 36
