Answer:
y = 2x - 1
Step-by-step explanation:
Note the difference between consecutive terms of y are constant, that is
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 9 - 7 = 2
Thus the equation is of the form y = 2x ± c ← c is a constant
Substitute values of x to determine the required value of c
x = 0 : 2 × 0 = 0 ← require to subtract 1 for y = - 1
x = 1 : 2 × 1 = 2 ← require to subtract 1 for y = 1
x = 2 : 2 × 2 = 4 ← require to subtract 1 for y = 3, and so on
Thus the required equation is
y = 2x - 1
Answer:
C
Step-by-step explanation:
X10+2y=50 pounds this is your answers because if you do 3 times what number is less than 50 but still is even because all you have afterwars are 10 so 10 is 30. then 30 +?=50 its 20 so 10 multply by two plus 3 multiply by 10 equals 50. hope this helps!!!!!!!!!!
Answer:
3
Step-by-step explanation:
To evaluate the expression, we have to substitute the variable in the expression, z, for its stated value. Given that z = 6, substitute 6 for the z in the expression and solve:
Thus, the answer is 3.
