Which is the equation of the line with slope 3 that contains point (-1, 5)?

1 answer:

5 0

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})~\hspace{10em} slope = m\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-5=3[x-(-1)] \\\\\\ y-5=3(x+1)\implies y-5=3x+3\implies y=3x+8$

Can someone please help me solve 1-|1/3q-5|=-6

FrozenT [24]

Hello,

2 cases:

if 1/3*q-5>0 then

|1/3*q-5|=1/3*q-5
1-|1/3*q-5|=-6
1-(1/3*q-5)=-6
1-1/3*q+5=-6
6-1/3*q=-6
-1/3*q=-12
q=36

else

|1/3*q-5|=-(1/3*q-5)
1-|1/3*q-5|=-6
1+(1/3*q-5)=-6
1+1/3*q-5=-6
-4+1/3*q=-6
1/3*q=-2
q=-6

What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?

fenix001 [56]

Step-by-step explanation:

$\to 1,728 \times {10}^{9}$

$= 1,728 \times {10}^{9}$

$= 1,728 \times 1.000.000.000$

$= 1.728.000.000$

$1,728 \times {10}^{9} = 1.728.000.000$

$\:$

$\to 4,8 \times {10}^{6}$

$= 4,8 \times {10}^{6}$

$= 4,8 \times 1.000.000$

$= 4.800.000$

$4,8 \times {10}^{6} = 4.800.000$
