Answer:
A. 3
Step-by-step explanation:
Let the integers be
x
(x+1)
(x+2)
(x+3)
Sum the integers
We have,
x+(x+1)+(x+2)+(x+3)=18
x+x+1+x+2+x+3=18
4x+6=18
Subtract 6 from both sides
4x-6=18-6
4x=12
Divide both sides by 4
4x/4=12/4
x=3
The smallest integer which is x is equal to 3
Check:
3+4+5+6=18
Answer:
No, the function has no real number zeros.

Answer:
Step-by-step explanation:
20 is a constant, the rate of change of y is 0.045x, so the rate is stated as 0.045
Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−4=3+8x
7x+−4=3+8x
7x−4=8x+3
Step 2: Subtract 8x from both sides.
7x−4−8x=8x+3−8x
−x−4=3
Step 3: Add 4 to both sides.
−x−4+4=3+4
−x=7
Step 4: Divide both sides by -1.
−x/−1=7/−1
x=−7
