Can you please help me with this? <br> 14 + 5(x + 3) - 7x
TEA [102]
Well first you have to do distributive property with the parenthesis, multiply 5 times x and 5 times 3 to get 5x and 15 now you have 14+5x+15-7x, now add common like terms(these are terms taht have the same number variable or both) so your common numbers will be 14 and 15, and 5x and -7x now add or subtract them to get -2x+29 now you have to set x by itself so set this binomial equal to 0 to get -2x+29=0 subtract the 29 from both sides and get -2x=-29 now divide 2 by both sides to get x=29/2

Hope this helps

(2x)^-1<br> how do u put this into a positive exponent and a fraction?<br> 20 points
Naddika [18.5K]

For this case we have that by definition of power properties it is fulfilled that:

a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}

Then, if we have the following expression:

(2x)^{ -1}

Applying the property, we can rewrite the expression as:

\frac {1} {(2x) ^ 1} = \frac {1} {2x}

Answer:

\frac {1} {2x}

Solving by Substitution <br><br> y=-2+1<br> 2x-2y=4
Kryger [21]
2x-2(-2+1)=4
Distribute the -2 to the numbers in parantheses.
2x+4-2=4
Combine all numbers
2x+2=4
Subtract 2 from both sides
2x=2
Then divide by two
x=1
