Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
ANSWER
Each side of the chip is 5 centimeters long.
<u>EXPLANATION</u>
The chip is in the form of a square.
The formula for finding the area of a square is
We were given in the question that, the area is 25 square centimeters. This means that,
We take the square root of both sides to get,
Hence the length of the square technology chip is 5 centimeters
1/5 or -1/9 would both be correct
we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For
the value of the function is equal to zero
is a x-intercept, because
For
the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts


The graph lines stay the same, however the y-intercept changes from (-1,0) to (-2,0), since it is now g(x) = x - 2, instead of f(x) = x - 1.
