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
1.) 5.52399e-5
3.) 62 (I think)
F(x)=x-4
f(3)=3-4=-1
(x-4)=3
x=7
3(f(x))=3(x-4)
3(f(3))=3(3-4)=-3
f(x)=7
Answer: 135
Step-by-step explanation:
7x- y, x = 20, and y = 5
7(20)-5=140-5=135
