Given the equation:

\log _2(7x)+\log _22=1

As we know: log a + log b = log (ab)

So,

\begin{gathered} \log _2(7x\cdot2)=1 \\ \log _2(14x)=\log _22 \\  \\ 14x=2 \\ x=\frac{2}{14} \\  \\ x=\frac{1}{7} \end{gathered}

So, the answer will be x = 1/7

What is the slope of the line in the given graph?<br> A) 1/2 B) -1/3 C) 3 D)-3
Karo-lina-s [1.5K]
We find the slope through the formula y2-y1/x2-x1
so when we plug in the values of our two points, we get
2-(-1)/(0-(-1))
this gets us 3/1
Which gives us the slope m=3

Please anwer what is X and give the explantion,how did you get the answer.ASAP
grigory [225]

We can solve x through simple algebra.

x + 5 = 2

x = 2 - 5

x = -3

x - 10 = 22

x = 22 + 10

x = 12

x - 27 = 8 + 10

x - 27 = 18

x = 18 + 27

x = 45

-11 + x + (-48) = 25

-11 + (-48) + x = 25

-59 + x = 25

x = 25 + 59

x = 84

x - (-16) = 12 + 13

x + 16 = 25

x = 25 - 16

x = 9

Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).

Find the area of the circle
vlada-n [284]

Answer:

A = 1.77 ft^2

Step-by-step explanation:

The circle has  a diameter of 1.5 ft

We need the radius

r = d/2 = 1.5/2 = .75 ft

The area of a circle is

A = pi r^2

A = 3.14 ( .75)^2 = 1.76625

To the nearest hundredth

A = 1.77 ft^2
