Answer:
b: 3x^2+y=5
Step-by-step explanation:
Turn them into linear equation.
4y + x = -17
-x -x
4y = -x - 17
--- ---- ---
4 4 4
y = -1/4x - 17/4
-2y + 2x = 16
-2x -2x
-2y = -2x + 16
----- ---- -----
-2 -2 -2
y = 1x - 8
Solve for x.
-1/4x - 17/4 = 1x - 8
+1/4x +1/4x
-17/4 = 5/4x - 8
+8 +8
15/4 = 5/4x
------ -----
5/4 5/4
3 = x
Check:
-1/4(3) - 17/4 = 1(3) - 8
-3/4 - 17/4 = 3 - 8
-5 = -5
Answer:
<u>Total yearly interest for the two accounts is: $1500</u>
Step-by-step explanation:
Total amount of money invested: $13000
x+y=13000,
Total yearly interest for the two accounts is: $1500
0.07*x+0.17*y=1500
x=13000-y
Substitute for x
0.07*(13000-y)+0.17*y=1500
Multiply out
910-0.07y+0.17*y=1500
Combine like terms.
0.1*y=590
Isolate y
y=$ 5900.00 at 17%
x=13000-y
Calculate x
x=$ 7100.00 at 7%
Check
0.07*7100+0.17*5900=1500
497+1003=1500
1500=1500
If this statement is TRUE and neither amount is negative then all is well
