Answer:
144
Step-by-step explanation:
f(4)=3*4^2
f(4)=12^2
12*12=144
-7x -7y = 21
Y = 6
Since they are giving you the value of 6 you just plug it in the equation
-7x - 7(6) = 21
-7x - 42 = 21
+ 42. +42
-7x = 63
/-7. /-7
X = -9
For the first one it might be 26? i’m not so sure
Final price=original price*(100%- discount 1)(100%-discount 2)
original price=$40
discount 1=25%⇒ 100 - discount 1=100%-25%=75%=75/100=0.75
discount 2=15%⇒ 100 - discount 2=100%-12%=85%=85/100=0.85
original price=$40(0.75)(0.85)=$25.5
