Hello,
Put the 3 as a common factor.
Look:
3x - 6 = 3 . ( x - 2 )
Then,
( 3x - 6) / (x - 2) = 3 .( x - 2) / (x -2)
Now simplity ( x -2)
= 3
Answer:
C. 5
Step-by-step explanation:
first expression 5 × (9-3) = 30
second one 45 - 3x
to make it 30 = 30
x should be = 5
Answer:
Please check explanation
Step-by-step explanation:
Here, we want to do a matching.
We shall be matching the given statements with the features we have on the graph
Hence we shall be looking closely at the graph to answer the questions.
The y-intercept is the point at which the graph touches the y-axis
And it was at -3 degrees celsius at the beginning of the day.
The temperature was above zero between 8am and 8pm. The matching statement is that it is increasing or decreasing interval
We can see that the graph rose from 8am before it finally comes to zero at 8pm
Positive or negative interval matches with it was getting warmer between 2am and 2pm.
While temperature was lowest at 2am, we can see a peak at 2pm.
Answer:
noestiendo
Step-by-step explanation:

it was raised to 83%
therefor
x+15=83
first option is right (and first test was 68%)
