Explain why the equation 5z + 2 = 5z has no solution.
suter [353]
5z + 2 = 5z \\ 5z - 5z = - 2 \\ 0 = - 2

Answer : This is because when 5z minus 5z, it is nullified, with no way to determine the value of z. 5z - 5z = 0
That is why there is no solution for this equation.

Hope this helps. - M

Solve the equation for y.<br>28 = 24x – 7y​
spin [16.1K]

28 = 24x -7y

-24x + 28 = -7y

y = 24/7x + 4

The graph below shows the height through which an elevator travels, y, in x seconds: A graph is shown with x axis title as Time
Blababa [14]

Answer:

C. 10

Step-by-step explanation:

We are given a graph representing the height of the elevator with respect to time.

Since, we know that,

X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.

As, the coordinate points on the graph are given by,

(1,10), (2,20), (3,30) and (4,40).

So, the rate of change can be found out by solving, \frac{20-10}{2-1}=10.

Hence, the rate of change of the relationship is 10.

Multiply and simplify to lowest terms when appropriate 11/9× 27/55
arsen [322]
11/9 * 27/55
First, you need to transform this expression to one fraction, by multiplying the numerators between each other and put the answer as one numerator, then the denominators and put the answer as one denominator.
11/9 * 27/55 = 297/495.
Now comes the simplifying. You need to divide both numerator and denominator by the same number, till you get an irreducible fraction (a fraction In which numerator and denominator can't be divided by the same number to get another whole number).
In this case, both 297 and 495 are divisible by 99.
297/99 = 3 and 495/99 = 5.
So 297/495 = 3/5.
3 and 5 can't be divided by a same number, so 3/5 represents the irreducible and simplified fraction.

You can re-check your answer (very important):
11/9 * 27/55 = 0.6
297/495 = 0.6
3/5 = 0.6
11/9*22/55 = 297/495 = 3/5
The answer has been approved.

Hope this Helps! :)
