F(-2) when F(x)=5^x is 1/25
Answer:
4p+9=
(first start with multiple or division division from right to left then with addition from right to left)
4*4+9=
16+9=25
Answer:
The last expression.
Step-by-step explanation:
The last expression is not a polynomial because x is in the denominator of the second term.
Y = mx + b; b = 6
<span>1 = 4m + 6; m = -5/4 </span>
<span>-5/4 = (1 + 2k) / (4 - k - 3) = (2k + 1) / (1 - k) </span>
<span>-5(1 - k) = 4(2k + 1) </span>
<span>5k - 5 = 8k + 4 </span>
<span>-3k = 9 </span>
<span>k = -3</span>
