Domain = all possible x values
You can see it starts from -5 and it goes till 4. Therefore domain -5 < x < 4
Solution: [-5,4]
1- Associative property of addition: E
-1+(4+9)=(-1+4)+9
2- Commutative property of multiplication: A
(-9)(0)=(0)(-9)
3- Commutative property of addition: D
-9+1=1+(-9)
4- Identity property of addition: B
-9+0=-9
5- Identity property of multiplication: F
(-9)(1)=-9
6- Associative property of multiplication: C
-1(4•9)=(-1•4)9
Answer:
y = (1/2)x is proportional; (1/2)
Step-by-step explanation:
1. y= 1/2x Proportional; constant of proportionality is 1/2.
2. y=2x + 7 Not proportional because of the non-zero y-intercept.
3. x= y + 2 Not proportional (same a reason as for #2)
The number of cups of flour per shortcake in Wyatt's recipe is given by
![\frac{3.15}{9} =0.35](https://tex.z-dn.net/?f=%20%5Cfrac%7B3.15%7D%7B9%7D%20%3D0.35)
The number of cups of flour per shortcake in Cora's recipe is given by
![\frac{2.4}{8} =0.3](https://tex.z-dn.net/?f=%20%5Cfrac%7B2.4%7D%7B8%7D%20%3D0.3)
The number of more cups of flour needed by Cora is given by 0.35 - 0.3 = 0.05 cups.
