Answer:

"I Only" is the correct answer

Step-by-step explanation:

Given inequality is:

-10>3x-6

In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.

So,

<u>I . -10</u>

Putting -10 in the inequality

-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36

The inequality results in true after putting x=-10 so -10 is the solution of inequality.

<u>II. 5</u>

Putting 5 in the inequality

-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9

The equality doesn't hold true for x=5 so 5 is not the solution of the problem.

<u>III. -1</u>

Putting -1 in the equation

-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9

Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.

Hence,

"I Only" is the correct answer as only -10 is the solution of inequality.

Write an exponential expression that is equivalent to (4^14)^-2<br><br><br><br> THANK UUU
Vladimir79 [104]

(4^14)^-2

=(4^{14})^{-2}

Apply the formula : (x^m)^n=x^{m*n}

We get:

=4^{14*(-2)}

=4^{-28}

=(2^2)^{-28}

=(2^2)^{-28}

Apply the formula : (x^m)^n=x^{m*n}

We get:

=2^{2*(-28)}

=2^{-56}

convert negative exponent into positive

=\frac{1}{2^{56}}

Hence final equivalent answer is \frac{1}{2^{56}}

You can also use 2^{-56} as exponent form if you don't want to remove negative sign from exponent.

10. The coordinates of C and D are 4 and -28 respectively, and F mdpt CD. Solve for:
Zigmanuir [339]

Answer:

a) mCD=7

b) mCF=7

c) mFD=7

d) F(2,-14)

Step-by-step explanation:

Let  the coordinates of C and D be (4,0) and (0,-28) respectively  and F is the midpoint of CD

a) mCD  

Slope formula  

m= \frac{y_2-y_1}{x_2-x_1}

m= \frac{-28-0}{0-4}

m= \frac{-28}{-4}

m= 7

mCD=7

b) mCF  

mCF=mCD

Hence mCF=7

c) mFD

mFD=mCD

Hence mFD=7

d) Coordinates of F :  mid point formula

Mid points Formula

x= \frac{x_2+x_1}{2}

x= \frac{0+4}{2}=\frac{0+4}{2}=2

y= \frac{y_2+y_1}{2}=\frac{-28+0}{2}=\frac{-28}{2}=-14

coordinates of F are (2,-14)
