I didn’t get an answer that matches your answer choices, but here are mine:
exact form: p = 69/7
decimal form: p = 9.857142
mixed number form: p = 9 (6/7)
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
Firstly , we will check continuity at x=1
we can use method
Suppose, f(x) is continuous at x=c
then it must satisfy
firstly , we can find limit
so, we get
now, we can find f(1)
so, we got
so, this is continuous at x=1
Hence , option-D...........................Answer
Is it supposed to say 7x rather than Z? If so then
If you make both equations = to 4y you can work out the answer so
4y =7x-4
4y = 36-3x
Then you put them equal to each other so
7x-4 = 36-3x
10x = 40
x = 4
You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6
So the answer is x = 4 and y = 6
