Advice:
I've seen this around quite a bit. what image is it referring to? I cannot answer this because there is no image.
lim h→0 f(x + h) − f(x)h= limh→0x+h −4xh= limh→04x−4(x+h)x(x+h)= limh→04hhx(x + h)= limh→04x(x + h)=4x2.
<span>A) X + y + z = 7
B) 2x − y + z = 7
C) 3x − z = 2
</span><span>C) z = 3x -2 Substituting this into equations A) and B)
</span>
<span>A) X + y + 3x -2 = 7
B) 2x − y + 3x -2 = 7 Adding A and B
3x + 6x -4 = 14
9x = 18
x = 2
</span>Since x = 2 then
<span>A) 2 + y + 6 -2 = 7
</span><span>A) y = 1
</span>A) X + y + z = 7
<span>A) 2 + 1 + z = 7</span>
z = 4
It is-12 for the determination
