Answer:

We conclude that:

  • -\left(9x\right)^0=-1

Step-by-step explanation:

Given:

-\left(9x\right)^0

To determine:

Explain how to solve the expression

<u>Solving the expression</u>

-\left(9x\right)^0

Apply the exponent rule

a^0=1,\:\quad \:a\ne \:0

so the expression becomes

-\left(9x\right)^0\:=\:-1

Therefore, we conclude that:

  • -\left(9x\right)^0=-1

. Identify this sequence: 12, 19, 26, 33, 40, 47. The next term is ______.
CaHeK987 [17]

Answer:

The next term is 54.

Step-by-step explanation:

Look carefully, and you will find that each number increases by 7.

12 + 7 = 19.

19 + 7 = 26.

26 + 7 = 33...

...and so on.

Therefore, the next term is 54 since 47 + 7 = 54.

Hope this helped!

Parallelogram ABCD has diagonal segments AC and BD that intersect at E. if BE is ( x + 8) and ED is (5 x), find the length of BD
Virty [35]

Answer:

BD = 20 units

Step-by-step explanation:

Given that,

Parallelogram ABCD has diagonal segments AC and BD that intersect at E.

BE = (x+8) and ED = 5x

We need to find the length of BD.

BD = BE + ED ...(1)

We know that the diagonals of a parallelogram bisects each other. It means,

BE = ED

x+8 = 5x

8 = 5x - x

8 = 4x

x = 2

BE = (x+8)

= (2+8)

= 10

ED = 5x

= 5(2)

= 10

Put the values in equation (1).

BD = 10 + 10

= 20 units

Hence, the length of BD is 20 units.

Given points A (1, 2/3), B (x, -4/5), and C (-1/2, 4) determine the value of x such that all three points are collinear
sleet_krkn [62]

Answer:

Step-by-step explanation:

Let B divides AB in the ratio K:1

x=\frac{nx1+mx2}{m+n} \\y=\frac{ny1+my2}{m+n} \\\frac{-4}{5} =\frac{1*\frac{2}{3}+k*4}{k+1} \\-4k-4=\frac{10}{3} +20k\\-12 k-12=10+60k\\72k=-22\\36k=-11\\k=-\frac{11}{36} \\

so B divides AB in the ratio 11:-36

x=\frac{-36*1+11 *\frac{-1}{2} }{11-36} \\x=\frac{83}{50}
