A^3b^-2c^-1d if a=2 b=4 c=10 d=15 express as a reduced fraction
I am Lyosha [343]

\bf a^3b^{-2}c^{-1}d\implies \cfrac{a^3d}{b^2c}\qquad \begin{cases} a=2\\ b=4\\ c=10\\ d=15 \end{cases}\implies \cfrac{2^3\cdot 15}{4^2\cdot 10}\implies \cfrac{120}{160}\implies \cfrac{3}{4}

Mila [183]
 <span>2**n. (That's two to the nth power: 2 to the first, 2 to the second (or two squared), 2 to the third (or two cubed), 2 to the fourth, etc.) 

2**1 = 2 = 2 
2**2 = 2 * 2 = 4 
2**3 = 2 * 2 * 2 = 8 
2**4 = 2 * 2 * 2 * 2 = 16 </span>

Match the graph shown with the following equation<br> Answer a and b please
julia-pushkina [17]

Answer:

a) D b)B

Step-by-step explanation:

a) the graph is of negative slope as it slants downwards hence slop/gradient is negative. y intercept is positive so only option d is right

b) sub each option point into 3y = 2x - 1 if they equate to be the same, it is correct.

3(2) = 2(6) - 1

6 = 11 (not equal)

3(1) = 2(2) - 1

3 = 3 (equal) this is the answer

of course you can sub in the rest to confirm but I'm lazy so yeah I'll stop here
