Jimmy - j years now
Beth -(j+2) years now
In 3 years
Jimmy - (j+3)
Beth -(j+2+3)=(j+5)
j+3 + j+5=(2j+8) - sum of their ages in 3 years
y years ago
Jimmy - (j-3)
Beth - (j+2-3)= (j-1)
j-3+j-1=(2j - 4) - sum of their ages in 3 years ago
(2j+8) =2(2j - 4)
2j+8 = 4j-8
2j = 16
j = 8
Jimmy - 8 years now
Beth - 8+2=10 years now
Answer:
Commutative property of addition, or just commutative property.
Step-by-step explanation:
The commutative property states that the order of numbers in addition does not matter, which is shown in the problem.
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
<span>The regular hexagon ABCDEF rotates 240º counterclockwise about its center to form hexagon A′B′C′D′E′F′. Point C′ of the image coincides with point _E_ of the preimage. Point D′ of the image coincides with point _F_ of the preimage.</span>
Answer:
The domain would be -3≤x≤2 and the range would be -5≤y≤4
Step-by-step explanation:
The domain is where the x values cover, so since on the graph the points range from having -3 as the x value to 2, x would be anything between or equal to these values.
The domain is where the y values cover, so since on the graph the points range from having -5 as the y value to 4, y would be anything between or equal to these values.
