First, put the equations into slope-intercept form(y = mx + b):
4x+5y=15\\5y=-4x+15\\y=\frac{-4}{5}x+3\\\\ 12x+15y=0 \\15y=-12x\\ y= \frac{-12}{15}x=\frac{-4}{5}x\\
y=\frac{-4}{5}x
Since slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept, the slope of the line(value of m) determines whether the lines are parallel or perpendicular.
Parallel lines have the same slope, and since \frac{-4}{5}=\frac{-4}{5}, the lines are parallel. Also, because the m's aren't the same, the lines aren't identical.

Your answer is parallel.

Explain how to use basic facts and number patterns to find 5,600 divide by 7
Charra [1.4K]
5600 can be simplified. Say you were to just take the two zeros off the end and you would have 56. Now divide 56 by 7 and you get 8. Add the zeros back to the 8 and your answer is 7 x 800. Hope this helps.

Answer:

\huge\boxed{(3^4)^4=3^8\cdot3^8}\\\boxed{4^3\cdot5^3=20^3}\\\boxed{(4^3)^3=4^3\cdot4^3\cdo4^3}

Step-by-step explanation:

a^n\cdot a^n=a^{n+m}\\\\(a^n)^m=a^{n\cdot m}\\\\(a\cdot b)^n=a^n\cdot b^n\\=====================

(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3=4^{3+3}=4^6\\\\4^9\neq4^6\to(4^3)^3\neq4^3\cdot4^3\\==================

(3^4)^4=3^{4\cdot4}=3^{16}\\3^8\cdot3^8=3^{8+8}=3^{16}\\\\(3^4)^4=3^8\cdot3^8\\================

6^4\cdot3^4=(6\cdot3)^4=18^4\\\\18^4\neq18^8\to6^4\cdot3^4\neq18^8\\=================

4^3\cdot5^3=(4\cdot5)^3=20^3\\\\4^3\cdot5^3=20^3\\=================

(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3\cdot4^3=4^{3+3+3}=4^9\\\\(4^3)^3=4^3\cdot4^3\cdot4^3
