Answer:
1st one
Step-by-step explanation:
-2 + n = -8(1 - 8n) + 6
Distribute the -8
-2 + n = -8 + 64n + 6
Combine like terms.
-2 + n = 64n - 2
Add 2 to both sides and subtract n from both sides.
0 = 63n
Divide both sides by 63
0 = n
Answer:
Step-by-step explanation:
Quadratic equation: ax² + bx + c = 0, where a ≠ 0
x² + 9x - 22
Factors of c (-22):
1 × -22 or -1 × 22
2 × -11 or -2 × 11
Sum of factors:
1 + (-22) = -21 or -1 + 22 = 21
2 + (-11) = -9 or -2 + 11 = 9

Answer:
t = (D/C - 1) (100/r)
Step-by-step explanation:
D = C(1+rt/100)
D/C = 1 + rt/100
D/C - 1 = rt/100
D/C - 1 = t (r/100)
Therfore,
<h2>t = (D/C - 1) / r/100</h2>
Therefore the last option is correct.

Answer:
{x,y}={−5,−7}
Explain:
// Solve equation [2] for the variable y [2] 3y = 7x + 14 [2] y = 7x/3 + 14/3 // Plug this in for variable y in equation [1] [1] 8x - 3•(7x/3+14/3) = -19 [1] x = -5 // Solve equation [1] for the variable x [1] x = - 5 // By now we know this much : x = -5 y = 7x/3+14/3 // Use the x value to solve for y y = (7/3)(-5)+14/3 = -7 Solution : {x,y} = {-5,-7}
