f(x)= -99.4x + 198.8
f(1) = -99.4*1 + 198.8 = 99.4
f(2) = -99.4*2 + 198.8 = 0
f(3) = -99.4*3 + 198.8 = -99.4
<span>f(4) = -99.4*4 + 198.8 = -198.8

Hi there!
<u>Here is the step by step explanation into solving this :</u>
4 × (2² + 5)² ÷ 3 - 1
Start by solving the inside of the parentheses
2² = 2 × 2 = 4
4 + 5 = 9
Distribute the "²" to the whole parentheses
9² = 9 × 9 = 81
4 × 81 ÷ 3 - 1
Do the multiplication, then the division and lastly the subtraction
4 × 81 = 324
324 ÷ 3 = 108
108 - 1 = 107
The answer is : 107
There you go! I really hope this helped, if there's anything just let me know! :)
1 ) 3 t ( t + 2 ) - 3 t² =
= 3 t² + 6 t - 3 t² = 6 t = 6 · 19 = 114
2 ) - ( 3 a - 2 b ) - 3 ( - a- b ) =
= - 3 a + 2 b + 3 a + 3 b = 5 b
Answer: 32 degrees
