Brian was asked to write x72 as a product of 2 powers with the same base in 4 different ways, using only positive exponents.

Oksana_A [137]

The equivalent expression to the value given using the laws of indices is ${x}^{4(18)}$

Evaluating the options given based on the laws of indices :

${x}^{8}. {x}^{9} = {x}^{8 + 9} = {x}^{17}$
${x}^{35}. {x}^{47} = {x}^{35 + 47} = {x}^{82}$
${x}^{4(18)} = {x}^{4 \times 18} = {x}^{72}$
${x}^{24}. {x}^{3} = {x}^{24 + 3} = {x}^{27}$

Therefore, the only expression which would give a correct way of representing ${x}^{72} \: is \: {x}^{4(18)}$

What is the resulting equation when the expression for y in the second equation is substituted into the first equation-3x+2y=-3

Alex

Answer:

x=-5/11, y=-9/11. (-5/11, -9/11).

Step-by-step explanation:

3x+2y=-3

y=4x+1

---------------

3x+2(4x+1)=-3

3x+8x+2=-3

11x=-3-2

11x=-5

x=-5/11

y=4(-5/11)+1

y=-20/11+11/11

y=-9/11

The mean of the data set is 15.What number is missing? 9,12,16,18,23

maxonik [38]

The number 12 is missing in the data set.

<u>Step-by-step explanation</u>:

The numbers are 9,12,16,18,23.
The missing number is assumed to be 'x'

Mean = Sum of the integers / Total number of integers.

15 = (9+12+16+18+23+x) / 6

15 = (78+x) / 6

90 = 78+x

x = 90-78

x = 12
