Answer:
x = -4 , y = 3
Step-by-step explanation:
5x - 7y = -41 ... (i)
-3x - 5y = -3 ... (ii)
Multiplying (i) by -3 and (ii) by 5 ;
-15x + 21y = 123 ... (i)
-15x - 25y = -15 ... (ii)
Subtracting (i) by (ii) ;
0 + 46y = 138
46y = 138
y = 138 ÷ 46 = 3
Returning to equation (ii) ;
-3x - 5(3) = -3
-3x = -3 + 15
-3x = 12
x = -4
.6 * 25 = 15
.06 * 25 = 1.5
Answer:
I think the answer would be A .
Answer:
(f×g)(x) = 2x³ +x² -14x -7
Step-by-step explanation:
(f×g)(x) = f(x)×g(x) = (2x +1)×(x² -7)
= 2x(x² -7) +1(x² -7)
= 2x³ -14x +x² -7
(f×g)(x) = 2x³ +x² -14x -7
