What does x equal? Please help

Mathematics
1 answer:
Norma-Jean [14]4 years ago
8 0

Answer:

x=-9

Step-by-step explanation:

9^{2x-3}=27^{2x+4}\\(3^2)^{2x-3}=(3^3)^{2x+4}\\3^{2(2x-3)}=3^{3(2x+4)}\\3^{4x-6}=3^{6x+12}

As the bases(3) are same,

we can conclude that the powers are equal.

Hence,

4x-6=6x+12\\-6-12=6x-4x\\-18=2x\\x=-18/2\\x=-9

Find the slope of the line that would pass
Leno4ka [110]

Answer:

10

Step-by-step explanation:

Here we go!

Slope Formula:

\frac{ {y}^{2} -  {y}^{1}  }{ {x}^{2} -  {x}^{1} }

What we know: (-4, -52) and (-1, -22)

Plug in the numbers!

\frac{ - 52 - ( - 22)}{ - 4 - ( - 1)}

Fix it!

\frac{ - 52 + 22}{ - 4 + 1}

Add

\frac{ - 30}{ - 3}

Divide

(negative divided by a negative is a positive!!)

Slope is 10

Hope this helps!

What is the approximate area of the figure?
Valentin [98]

Answer:

Answer D (2206.5 ft^2) is closest to the calculated answer 2206.85 ft^2.

Step-by-step explanation:

We can break up this figure into a 30 ft by 50 ft rectangle and a circle of diameter 30 ft.

The area of the rectangular part is A1 = (30 ft)(50 ft) = 1500 ft^2.

The area of the circular part is A2 = π(15 ft)^2 = 706.9 ft^2

Thus, the total area is approx A1 + A2, or 2206.86 ft^2 (Answer D)
