Y = 7x + b
2 = 7 + b, b = -5
Y = 7x - 5
Hi there!
One way to find the solution is to list out all of the possible combinations- which, in most cases, will take a long time.
<u>Another more effective way</u> to find the possible combinations is to multiply the amount of each component together and find the product of all of the amounts of items combined.
In this case, you would multiply:
6 * 3 * 3 * 3 * 3
= 486.
So, there'd be 486 combinations.
Hope this helps!
Answer: -5
Step-by-step explanation: since he only had 80 in his checking
Deck=456
area of pool=legnth times width=20 times 50=1000
the area of the deck is made up of 4 rectangles and 4 squares, the rectangles' areas come in pairs
areas are
area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)
distribute
456=40w+4w^2+100w
add like terms
456=4w^2+140w
divide everybody by 4
114=w^2+35w
subtract 114 from both sides
0=w^2+35w-114
find what 2 numbers multiply to get 114 and add to get 35 and factor
-3 and 38
0=(w-3)(w+38)
set each to zero
w-3=0
w=3
w+38=0
w=-38
false since measures in real life cannot be negative
therfor width of walkway=3ft
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
x < 3
