Find the gradient of the line segment between the points (0,2) and (-2,10).​
Tasya [4]

Answer:

-4

Step-by-step explanation:

Find the gradient of the line segment between the points (0,2) and (-2,10).​

Given data

x1= 0

x2= -2

y1= 2

y2=10

The expression for the gradient is given as

M= y2-y1/x2-x1

substitute

M= 10-2/-2-0

M= 8/-2

m= -4

Hence the gradient is -4

Find the missing value for log4 9- log4 11= log 4 [ ]
Alexandra [31]

Answer:

Step-by-step explanation:

Hi there,

To get started, recall the logarithm rules. For this question, we can use the log rule specifically when subtracting two log functions that have the same base:

log_b\alpha -log_b\beta =log_b[\frac{\alpha }{\beta } ]

In this prompt, our base is 4, so b in the above formula. Using this formula, we can find the missing <u><em>argument</em></u> (the number inside of the log, what we are asked to solve for):

log_49-log_411=log_4[\frac{9}{11} ]\\   hence the missing argument is 9/11

At this point, there is no easier say to simplify, unless you wish to approximate  9/11 as 0.818. If you wish to solve for the exponent, you will have to use common log or natural log to do so.

If you liked this solution, leave a Thanks or give a rating!

thanks,
