Step-by-step explanation:
there are 480 chairs
2x-3y= -4 because 2x=8 since x=4 so,
8 - 3y = 20
-8. -8
-3y = 12

-3
y = -4
Answer: P=450
Step-by-step explanation:
add 41 to both sides of the equation
419 + 31 = p - 31 + 31
Answer:
If un= 3n+2, find u, and u Show that u n+1-Un= 3. 2. (i) If un=n2-3, find u , u ... If un= 3 + n(n-1), show that unti-un= 3n2-n. ... Sn=[a+(n-1)d] + [a + (n - 2)d] +.
Step-by-step explanation:
Step-by-step explanation:
<h3>let ,(-3,-8)=(X2,y2)</h3>
(-3,5) =(x1,y1)
then
slope (M) =
![(y2 - y1 ) \div x2 - x1)](https://tex.z-dn.net/?f=%28y2%20-%20y1%20%29%20%5Cdiv%20x2%20-%20x1%29)
={(-8)-5 }÷{(-3)-(-3)}
= -13÷ 0
=0
