A coefficient is the number in front of the variable
If you are dividing any number by a divisible of 10, you count the zeros and move the decimal that many spaces to the left. So with 100, there are 2 zeros, so 505. turns into 5.05.
15 mph = 15 miles traveled in a one hour time span.
15+3=18 miles, 60 minutes- 30 minutes = 30 minutes.
18 miles in the span of 30 minutes
Answer:
The inequality would be 4x + 9 ≥ 0
Step-by-step explanation:
You could use this inequality to solve the domain as any number can be put into this equation as long as it doesn't make what is under the square root symbol (4x + 9) negative. Therefore, you can build this inequality and solve from there if you would like.
<span>A. 3(4x - 4) - 7x = 12x - 12 - 7x = 5x - 12 yes
B. -3(4x - 4) - 7x = -12x + 12 - 7x = -19x + 12 no
C. 3(-4x + 4) - 7x = -12x + 12 - 7x = -19x + 12 no
D. -3(-4x - 4) - 7x = 12x + 12 - 7x = 5x + 12 no
Answer is A.</span>
