Pls help 3 question answer all of them true of false helllppp

Answer:

Step-by-step explanation:

x-4 = log (base3) of 6; add 4 to both sides

x= [log (base3) of (2*3) ] +4; split 6 to 2*3

x= [log (base 3) of 3 + log ( base 3) of 2] + 4; use rule log(ab) = log a+log b

x= log (base 3) of 2 + 1+ 4; use rule log (base a) of a = 1

x= log (base 3) of 2 + 5; put in the calculator

x≈5.63

Answer:

6:10pm

Step-by-step explanation:

At 6:00 the hands are 180° apart.

The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.

The minute hand moves 1/60 of the circle per minute = 6° per minute

Angle between the hands decreases by 6-0.5 = 5.5° per minute.

180 - 5.5t = 125

t = 125/5.5 = 10 minutes

The hands are 125° apart at t minutes after 6:00, or 6:10.

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

[tex] - 1 = \frac{x - 3}{ 2} [/tex]

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

[tex] - 2 = x - 3[/tex]

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

[tex]1 = x[/tex]

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

Answer:

(21 + 11)2 = 64

So, I don't think teachers do this, but this is my way of doing it

Okay, so first, I divided 64 by 2 :

64 ÷ 2 = 32

Then, I subtracted 11 from 32:

21

Now, to check, just do the problem :

(21 + 11)2 = 64

      32 * 2 = 64

Answer:

The solutions are:

[tex]m=-3,\:m=-19[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(m\:+11\right)^2=\:64[/tex]

[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

solving

[tex]m+11=\sqrt{64}[/tex]

[tex]m+11=\sqrt{8^2}[/tex]

[tex]m+11=8[/tex]        ∵ [tex]\sqrt{8^2}=8[/tex]

Subtract 11 from both sides

[tex]m+11-11=8-11[/tex]

Simplify

[tex]m=-3[/tex]

now solving

[tex]m+11=-\sqrt{64}[/tex]

[tex]m+11=-\sqrt{8^2}[/tex]

[tex]m+11=-8[/tex]      ∵ [tex]\sqrt{8^2}=8[/tex]

Subtract 11 from both sides

[tex]m+11-11=-8-11[/tex]    

Simplify

[tex]m=-19[/tex]

Thus, the solutions are:

[tex]m=-3,\:m=-19[/tex]

Answer:

Carter has to save for 3 months.

Step-by-step explanation:

120+25x=195

If you add 25 to 120, 3 times you get 195.

Therefore your answer is 3 months.

Mark brainliest pls and thank you.

Answer:

19 months

Step-by-step explanation:

As an equation, this can be represented as: x=4000(1.13ᵃ), where x is the amount being produced now and a is the time in months. To find our answer, let x equal 40,000.

40000=4000(1.13ᵃ)

10=1.13ᵃ

log(1.13)(10)=a

a≈18.84, or 19 months
