Answer:
60° is the value of y....
Answer:
y= -4x -3
Step-by-step explanation:
y1-y2=m(x1-x2)
3-(-3)= m(-4-(-1))
rise/run= slope
y/x= -4/1= -4
3-(-3)= -4(-4-(-1))
3-(-3)= 6 because the negative and minus cancel each other leaving 3+3=6.
-4-(-1)= -3 because minus and negative cancel each other leaving -4+1= -3.
y= -4x -3
The amount invested by Mr.Smith in 5% is $240 .
<u>Step-by-step explanation:</u>
We have , Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720 . Let us suppose that Mr.Smith invest $x so :

Now, total investment is $720 so,
+( ) = $720
