Y = 7x + 4
-4 from both sides
y - 4 = 7x
/ 7 on both sides
(y-4)/7 = x

Answer:

x = (y-4)/7

Answer:

x= (y - 4)/7

Step-by-step explanation:

y=7x + 4

Subtract 4 from both sides

y - 4= 7x +4 - 4

y - 4= 7x + 0

y - 4= 7x

Divide both sides by 7

(y - 4)/7= 7x/7

(y - 4)/7= x

x= (y - 4)/7

jonny [76]

Answer:

$\mathrm{Factor}\:4x^4-32x^3-60x^2:\quad 4x^2\left(x^2-8x-15\right)\\$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c\\x^3=xx^2\\x^4=x^2x^2\\=4x^2x^2-32xx^2-60x^2\\\mathrm{Rewrite\:}60\mathrm{\:as\:}4\cdot \:15\\\mathrm{Rewrite\:}32\mathrm{\:as\:}4\cdot \:8\\=4x^2x^2-4\cdot \:8xx^2-4\cdot \:15x^2\\\mathrm{Factor\:out\:common\:term\:}4x^2\\=4x^2\left(x^2-8x-15\right)$

Hope this helps and have a great day!!!
