Answer:

Step-by-step explanation:

4(3x + 2) - 5(7x + 5) <em>use the distributive property: a(b + c) = ab + ac</em>

= (4)(3x) + (4)(2) + (-5)(7x) + (-5)(5)

= 12x + 8 - 35x - 25 <em>combine like terms</em>

= (12x - 35x) + (8 - 25)

= -23x - 17

Start by using distributive property 4 x 3x and 4 x 2 then -5 x 7x and -5 x 5
Then you would take the total from 4 x 2 and 4 x 3x which equals 12x+8 and subtract it by the total for -5 x 7x and -5 x 5 which equals -35x-25
Next you would combine like terms -35x plus 12x and 8-25
-23x-17 would be your answer

What is the equation of this line in standard form? (-4, -1) & (1/2, 3)

BabaBlast [244]

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{\frac{1}{2}}~,~\stackrel{y_2}{3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{3}-\stackrel{y1}{(-1)}}}{\underset{run} {\underset{x_2}{\frac{1}{2}}-\underset{x_1}{(-4)}}}\implies \cfrac{3+1}{\frac{1}{2}+4}\implies \cfrac{4}{~~\frac{9}{2}~~}\implies \cfrac{4}{1}\cdot \cfrac{2}{9}\implies \cfrac{8}{9}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-1)}=\stackrel{m}{\cfrac{8}{9}}[x-\stackrel{x_1}{(-4)}]\implies y+1=\cfrac{8}{9}(x+4) \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{9}}{9(y+1)=9\left( \cfrac{8}{9}(x+4) \right)}\implies 9y+9=8(x+4)\implies 9y+9=8x+32 \\\\\\ 9y=8x+23\implies -8x+9y=23\implies 8x-9y=-23$
