Answer:
90 degrees
Step-by-step explanation:
Answer: x=-7/2 y=29/2
Steps:
Use the elimination method
Multiply -3x+y=4 by 5 to make the coefficient next to the y in both equations the same
5(-3x+y=4)
-15x+5y=20
Then, subtract to eliminate the y
-15x+5y=20
- -9x+5y=-1
= -6x=21
Divide both sides by -6 to isolate x
= x= -7/2
Next substitute -7/2 into x in one of the equations
-3(-7/2)+y=4
-21/2+y=4
Add 21/2 from both sides to isolate y
y=29/2
Answer:
The 2nd and last options.
Step-by-step explanation:
By looking at the table we know that the 2nd one is an answer for sure.
Also by looking at the table we know that the 3rd and 4th are not true.
put in -1/2 in the function to see if you get -2
1/2(-1/2)+3/2
-1/4+3/2
-1/4+6/4
5/4
So The first one doesn't work either.
Now the last one:
1/2(4)+3/2
4/2+3/2
7/2
So the last one works too.
Hope this helps :)
So you take $60 and multiply it by (100-5)% which is 95% , or
60*.95 = $57
$57
This graph clearly shows that the curve intersects the x-axis at (-5,0). This point is the "zero" of the function.
