Answer:
-11
Step-by-step explanation:
start with PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction)
so you would first start with 14 + (-12) so the + and - become a negative so it becomes 14 - 12 which is 2
so then do -8-5 which is -13
so then you combine them and get 2-13 which is -11
Answer:
one solution : x = - 1
Step-by-step explanation:
hello :
2 ^ (x ^ 2 + 2x) = 2 ^ - 1 means : x²+2x=-1
x²+2x+1 = 0
(x+1)² = 0
one solution : x = - 1
Answer:
Step-by-step explanation:
a )
5⁵ = 3125 and 5⁴ = 625
log5(3125) = 5 and log5(625) = 4
so log5(2350) will be greater than 4 but less than 5 .
b )
10⁶ = 1000000 and 10⁵ = 100000
log10( 1000000) = 6 and log10( 100000) = 5
log(113700) will be greater than 5 but less than 6
c )
2¹¹ = 2048 and 2¹⁰ = 1024
log2( 2048) = 11 and log2(1024) = 10
log2(1144) is more than 10 but less than 11 .
Answer:
X=2 and y=5
Step-by-step explanation:
2 represent x-value and 5 represent y- value
Answer:
10x+13y
Step-by-step explanation:
remove parentheses:
2x+3y+8x+10y
add like-terms:
2x+8x+3y+10y
add numbers with the same variables/elements
10x+3y+10y-->10x+13y
hope this helps
