Step-by-step explanation:

First you gotta write it in standard form

y - 3 = -5(x-1)

distribute -5(x-1) = -5x + 5

y - 3 = -5x + 5

+3 +3

y = -5x + 8

Solve 7x-4 = 5x+15 for x

tatiyna

$\bf{Hey\ there!}$

$\bf{7x-4 = 5x+15}$

$\bf{\underline{Subtract}\ 5x\ from\ \ on \ both\ of\ your\ sides!\downarrow}$

$\bf{7x-4-5x=5x+15-5x}$

$\bf{2x-4=15}$

$\bf{\underline{Add}\ by\ 4\ on\ each\ of\ your\ sides!\downarrow}$

$\bf{2x-4+4=15+4}$

$\bf{Cancel:-4+4\ because\ it\ equals\ 0}$

$\bf{Keep:15+4\ because\ it\ helps\ us\ solve\ for\ your\ answer}$

$\bf{15+4=19}$

$\bf{2x=19}$

$\bf{\underline{Divide}\ by\ 2\ on\ your\ sides!\downarrow}$

$\bf\frac{2x}{2}=\frac{19}{2}}$

$\bf{Cancel:\frac{2x}{2}\ because\ that\ gives\ you\ 1}$

$\bf{Keep:\frac{19}{2}\ because\ it\ gives\ you\ the\ the\ value\ of\ x}$

$\boxed{\boxed{\bf{Answer:x=\frac{19}{2}}}}\checkmark$

$\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}$

When the factors of a trinomial are (x+p) and (x-q) then the coefficient of the x-term in the trinomial is:

kondor19780726 [428]

Answer:

p - q

Step-by-step explanation:

Given the factors

(x + p)(x - q) ← expanding the factors

= x² - qx + px - pq ← collect like terms

= x² + px - qx - pq ← factor out x in each of the x- terms

= x² + (p - q)x - pq

The coefficient of the x- term is p - q
