Answer: -6

Step-by-step explanation:

y=-3 so y+1 could be replaced by -3+1 which is -2 leaving your equation looking like this 2x-7(-2) next you want to multiply -7 and -2 to get -14. So now you have 2x-14, well x is four and 4x2 is 8 so your equation is now 8-14, which leaves you with -6. Hope this helps and have a good day!

Whats the rule for this pattern, 3,1.5,0,-1.5,-3

igomit [66]

The pattern subtracts 1.5 for each number in the pattern. 3-1.5 is 1.5. 1.5 minus 1.5 is zero. 0 minus 1.5 is -1.5. -1.5 minus 1.5 is negative 3. If we apply this rule to the next value, it would be -3 minus 1.5 which is equal to 4.5. The value after that would be 6, applying the same rule.
