Answer:
Dawn has $1670 in account 1 and $1570 in account 2.
Step-by-step explanation:
Dawn can multiply the second equation by 8 and add 7 times the first equation.
8(3/8A +7/8B) +7(A -B) = 8(2000) +7(100)
10A = 16,700
A = 1670
B = 1570 . . . . 100 less than A
Dawn has $1670 in account 1 and $1570 in account 2.

<em>Check</em>
3/8(1670) +7/8(1570) = 626.25 +1373.75 = 2000
-1 because y-intercept is where y meets zero, therefore the y intercept of this graph would be -1<3
20,000 + 3,000 + 400 + 30 + 6
Answer:
(x, y) = (20, 449)
Step-by-step explanation:
When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...
21.95x +10 = 22.45x
10 = 0.50x . . . . . subtract 21.95x
20 = x . . . . . . . . .multiply by 2
y = 22.45x = 22.45·20 = 449
