Step-by-step explanation:
arithmetic operations in functions are simple : you take both expressions and apply the arithmetic operation on them.
in our case : addition.
f(x) = 4x² + 5x - 3
g(x) = 4x³ - 3x² + 5
(f+g)(x) = (4x² + 5x - 3) + (4x³ - 3x² + 5) =
= 4x² + 5x - 3 + 4x³ - 3x² + 5 =
= 4x³ + x² + 5x + 2
so, B should be the right answer (despite all the typos there).
That is B.
Reflection in y-axis taking the Point A to (-1,3)
then 2 units to the left.
Answer:
1425
Step-by-step explanation:
∑ 1 ^30 (3n+1)=4+7+10+... 30 terms
a=4
n=30
d=7-4=3
S = D/t
120 = D / 0.5
D = 120*0.5
D = 60 km
S = D/t
70 = D / 2.5
D = 70*2.5
D = 175 miles
