1. -88 = -3(4m + 5) - (1 - 3m)​
Vadim26 [7]

Answer:

m=8

Step-by-step explanation:

-88=-3(4m+5)-(1-3m)

-88=-12m-15-(1-3m)   <- Distributive Property

-88=-12m-15-1+3m  <- Open () if there is a negative negative the symbol equals positive

-88=-9m-16    <- Simplify

0=-9m+72   <- Add 88 to both sides

9m = 72 <- Add 9m to both sides

9m = 72

/9      /9

m=8

Can someone help me plz
ankoles [38]
The answer should be 4. Take note of the pattern of unit digits of 2^n.

2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32


Every 4 powers, it rotates 2, 8, 6, 4. Since 2020 is divisible by 4, the answer is 4.

The equation is:
f ( x ) = 4 * 5 ^{2x}
f ( - 1 ) = 4 * 1/25 = 4/25 ( false )
f ( 0 ) = 4 * 1 = 4 ( false )
f ( 1 ) = 4 * 25 = 100 ( false )
f ( 2 ) = 4 * 5 ^4 = 4 * 625 = 2500  ( correct )
