y=2x+8
substitution method
Answer:
No Solution.
Step-by-step explanation:
2(x-1)-y=-8
y=2x+8
----------------
2x-2-(2x+8)=-8
2x-2-2x-8=-8
2x-2x-2-8=-8
0-2-8=-8
-2-8=-8
-10=-8

Answer: The function shows by the table is cubic function.
Explanation: Since, the given values of the function are
f(x): –29 –10 –3 –2 –1 6 25
First difference: 19 7 1 1 7 19
Second difference: -12 -6 0 6 12
Third difference: 6 6 6 6
Since, here, the value in third difference is repeating to 6. Therefore, according to the definition of successive difference, equation must have three degree. So, it is a cubic equation.
Express your answer as a whole number.
Answer:
Question 1
Area = Length x Width
Width = Area / Length
25/54 / 5/9
This is the same as:
25/54 x 9/5
225/270 is your answer
this can simplify to 5/6
Question 2
5/12 x 5/6 =
find common denominator
5/12 x 10/12 = 15/12 = 1 1/4 ft.
