Answer:
The system is given by the two equations:
x + y = 100000
0.06*x + 0.085*y = 0.08*(100000)
Step-by-step explanation:
The total money Connor has is $100,000. He wants to split it between two accounts, therefore the money that he'll apply on one account "x" plus the money that he'll apply on the other account "y" must be equal to the total he has. The first equation of the system, must be:
x + y = 100000
Since the first account gives a return of 6% and the second account gives a return of 8.5%, then the first account will give a return of 0.06*x and the second account will give a return of 0.085*y. The sum of this values must be equal to what he desires to recieve, therefore:
0.06*x + 0.085*y = 0.08*(100000)
The system is given by the two equations:
x + y = 100000
0.06*x + 0.085*y = 0.08*(100000)
Use a calculator and get 4.72
X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people
1) y=(7/2)x-2.
Slope is the coefficient of x, that is 7/2
Intercept x is the value of x when y = 0 ==> 0=(7/2) X - 2==> 7/2x=2 &x=4/7
so intercept x, (4/7,0)
Intercept y is the value of y when x=0 ==> y= (7/2).(0) - 2 ==> y = 2
and so intercept y, (0,-2)
Now you will follow the same logic to find the are same questions
2) y= -6x + 3 ==>Slope= -6, Intercept x =1/2 & intercept y=3
3) y=-5 has a slope 0 (it doesn't exist). The graph is a line // to x-axis at y=-5
4)y=(6/5)x + 1:==>Slope= -5/6, Intercept x =-5/6 & intercept y=1
5) y=(1/4)x + 2 ==>Slope= 1/4, Intercept x =-8 & intercept y=2
6) x=5, this ligne is // to y axis at x=-5
A fraction is not an integer.
