Answer:
11
Step-by-step explanation:
W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))
W^?/W² = W^?-2
W^9=W^(?-2)
9=?-2
?=11
W^7/W^-2 = W^11/W²
Answer:
1. x = 5 2. y = 4 3. x = -2
Step-by-step explanation:
2x - y = 9 -5x + 2y = 13 3x + 4y = -6
<u>4x + y = 21</u> <u>5x + y = -1 </u> <u> 7x(-1) + 4y(-1) = -14(-1)</u> <(multiply all by -1)
<u>6x = 30 </u> <u>3y = 12</u> <u> -4x = 8</u>
6 6 3 3 4 4
x = 5 y = 4 x = -2
