Rate of change is m in y=mx+b
also, starting value=when x=0
since so many questions I will not show work
1. A positive
2.B negatvie
3.B negative
4.B negative
2. B y=5x+4
3. B y=7x-8
4. C 12x+6y=30
5. plumber=140
electrition=115
per our means how much does he charge for 1 hour so subsitute 1 for x or find where 1 is
37% get less than 8 hours of sleep, 100%-37%=63%
63% get 8 hours or more per night:
(0.63)(2200)=1386
ANSWER: You would expect 1386 to get 8 or more hours of sleep per night.
A=LW
2x^2
v^2
(x+9)(x+8)
(2v-7)(2v-1)
(n-8)^2
6(t-3)(t+3)
(y+11)(y-11)
The cross section is a rectangle.
Hope this helps :)
First u gotta estimate what the answer u think it is. Then u turn the 2 into an 8 by multiplying both the numerator (which is 1) and denominator (which is 2) by 4 to make it 8. U then get the answer 5 4/8 and u then subtract the 5 4/8 with the 5/8 to get the answer. This was only for the first one tho!!!
