For the function, f(x) = 8x + 5x, find the following. (a) f(5) d nud k (b) f(-2) orea (c) f(4.2) muca (d) f(-4.2)

(a) 65

(b) -26

(c) 54.6

(d) -54.6

Step-by-step explanation:

(a)

(b)

(c)

(d)

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
