Answer:
-4 and -2
Step-by-step explanation:
f(x) = 1 means y = 1
When y = 1, x could be either -4 or -2 so the values of x when y = 1 are -4 and -2
Answer:
(4, 1)
Step-by-step explanation:
3x+4y=16 /*4
-4x-3y= - 19 /*3
12x + 16y = 64
<u>- 12x - 9y = - 57 </u>
7y = 7
y = 1
3x+4y=16
3x + 4*1 = 16
3x = 16 - 4
3x = 12
x = 4
Go to cymath and type it in and it will work it out for you and tell you the answer
A true
because 53•(41•11)=23,903 and (53•41)•11=23,903
