Step-by-step explanation:
4+(-3)-2*(-6)
4-3-2*-6
1-(-12)
1+12

A) The intersection occurs at the same height 'y', so the y of each equation must be equal:
y=y implies <span>2−x = 8x+4. The solution is -2=9x, x = -2/9=2/3, and y = 20/9
(-2/9,20/9)
</span>
B)
X | Y1 | Y2
_____________
-3 5 -20
-2 4 -12
-1 3 -4
0 2 4
1 1 12
2 0 20
3 -1 28
C) I would draw each line with the values on the table. Where both lines cross is the intersection point. It should be (-2/9, 20/9)
3 is not equivalent to -3, however it is the exact opposite of 3 I hope this helped ^^

Lexi borrowed $425 and paid back $450, so the interest paid was $25 (subtract 450 and 425). Then divide the interest over the expression P*t = 425*0.5 = 212.5 to get 25/212.5 = 0.1176 approximately which converts to the annual interest rate of 11.76% (approximately).
If you want to use a formula, then,
i = P*r*t
25 = 425*r*0.5 <---- t = 0.5 to represent half a year
25 = 4250.5*r
25 = 212.5*r
212.5*r = 25
r = 25/212.5
r = 0.1176
r = 11.76%
