Answer:
f(4) = -11
Step-by-step explanation:
Plug in 4 for x: Note that x = 4.
f(x) = -2x - 3
f(4) = -2(4) - 3
Remember to follow PEMDAS. First, solve the multiplication, then subtract:
f(4) = (-2 * 4) - 3
f(4) = (-8) - 3
f(4) = -11 is your answer.

(1) False
(2) False
(3). False
(4) False
According to the problem, calculation of the given data are as follows,
(1). Given, 149 + 769 = 819
By calculating 149 + 769 = 918
Hence, False
(2). Given, 556 + 336 = 826
By calculating 556 + 336 = 892
(3). Given, 458 - 248 = 238
By calculating 458 - 248 = 210
(4). Given, 658 - 228 = 438
By calculating 658 - 228 = 430
A chicken has 2 legs, a pig has four. 13 pigs x 4 legs each = 52
4 chickens x 2 legs each = 8
52+8= 60 legs in total
So there are 13 pigs and 4 chickens
The answer is
T= 5j+s+2
D
a^2+b^2=c^2
7^2+9^2=C^2
49+81=c^2
=c
