1. (a) for Y axis, put x=0 in the equation of the line to get: y=3(0)+5
y=5 at P
(B) Two lines are parallel if they have the same slope. Given slope m= 3 (from y=mx+b)
therefore the equation of the line parallel to the given line is:
y= 3x+b
X^2+14x-176=0
(x+22)(x-8)
x=-22,8
This is because the 2 numbers in the factorisation must have multiple of 176& and a sum of 14
2w+2l=60 and l = 3w+2
All we need to do to find width is substitute the length in the perimeter formula with the length formula we have established.
2w+2(3w+2)=60
2w+6w+4=60
8w+4=60
8w=56
w=7
width is 7 feet
Answer: B
Step-by-step explanation: 3^4 is 81, and 3^2 is 9. 81/9 is 9. :)
