Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
Answer:
<em>83.33%</em>
<em>Total no. of students = 720</em>
<em>No. of students who failed = 120</em>
<em>Therefore no. of students passed = 720 120= 600</em>
<em>Therefore pass percentage = 600/720* 100 = 83.33%</em>

I can’t see the image. I’ll still try to help. The line has to cross 7 on the y-axis (|). The line is positive so it should look something like this “/“ By doing rise over run, (5/1) It is supposed to go up 5 times for every one time it goes to the right. Sorry if this explanation is a little confusing. This is the most I can do without seeing the image.
1.5. if you divide the denominator by the numerator you will get your decimal.
Answer:

Step-by-step explanation:
We are given the equation

In order to solve for r, we must divide each side by 7

This then simplifies to
