2 answers:
Answer : -4
Step-by-step explanation:
Let the no. be x
4(2x+6) = -8
8x+24 = -8
8x = -8 - 24
8x = -32
x= -32 / 8
x= -4
Hey there! :)
Answer:
x = -4.
Step-by-step explanation:
We can write an algebraic equation to express this situation.
Let 'x' represent a number:
4(2x + 6) = -8.
Begin by dividing both sides by 4:
2x + 6 = -2
Subtract 6 from both sides:
2x + 6 - 6 = -2 - 6
2x = -8
Divide 2 from both sides:
2x/2 = -8/2
x = -4.

x=-4
2nd one
-15=15q-50 - 5q
35= 10q
q = 3.5
it’s not an exponential function because it is a quadratic function
an exponential function is y=2^x
