It’s “A” because you need to add the four sides together which gets you the 40 cm sorry if it is wrong but I think it is that

Solve for y. log 5+log y=log 40 enter your answer in the box.
Vadim26 [7]

Answer:

The value of y for given log function is 8 .

Step-by-step explanation:

Given as :

The log function is Log 5 + Log y = Log 40

Or, Log y = Log 40 - Log 5            .........1

∵<u> From the Log property</u>

Log m - Log n = Log \dfrac{m}{n}

So, Log 40 - Log 5 = Log \dfrac{40}{5}

Or, Log 40 - Log 5 = Log 8            .........2

Now, From eq 1 and 2

Log y = Log 8

∴  y = 8

So, The value of y = 8

Hence, The value of y for given log function is 8 . Answer

Degger [83]

Answer:

y=-3x+10

Step-by-step explanation:

Since you know that the equation of the line is perpendicular to 1/3, you have to find the inverse of 1/3. You swap the denominator and numerator and make the number negative. In this case, it will be -3. Now that you know the slope is -3, you can use the equation y-y1=m(x-x1) where m is the slope. We know that the point (2,4) is in the graph so we can plug it into the equation. y-4=m(x-2). We know that the slope is -3 so we can plug it into the equation. y-4=-3(x-2). Simplify this to get y-4=-3x+6. Simplify this to get y=-3x+10. This means that the answer is y=-3x+10.

Write the equation in its equivalent logarithmic form.
Oksanka [162]
Logₐx=b means aᵇ=x
reverse

aᵇ=x means logₐx=b
so
2³=x means log₂x=3

I say it is A
