Which equation is equivalent to 7(x-2) = 149? Will give Brainly points

Effectus [21]

Answer:

B. $\log_{7} 149+2 = x$

Step-by-step explanation:

Let $7^{x-2} = 149$ , we proceed to find its equivalent expression by applying logarithm properties:

1) $7^{x-2} = 149$ Given.

2) $\log_{7} 7^{x-2} = \log_{7} 149$ Definition of logarithm.

3) $(x-2)\cdot \log_{7}7 = \log_{7} 149$ $\log_{a} b^{c} = c\cdot \log_{a} b$

4) $x-2=\log_{7}149$ $\log_{a}a = 1$

5) $x = \log_{7}149+2$ Compatibility with addition/Existence of additive inverse/Modulative property

6) $\log_{7} 149+2 = x$ Symmetrical property/Result.

Hence, the right answer is B.

forsale [732]

Answer:

$Quadrant\ IV = (5, -3)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Step-by-step explanation:

Given

$Quadrant\ IV = (5, -3)$

$Quadrant\ II = (-4, -8)$

$Quadrant\ I = (9, 11)$

$Quadrant\ II = (-1, 3)$

$Quadrant\ III = (-2, -4)$

Required

Determine which coordinate fall in the right quadrant

First, we split the each quadrant into x and y axis

In the first:

x and y is +

In the second:

x is - and y is +

In the third

x and y are -

In the fourth

x is + and y is -

Comparing the given coordinates to their respective quadrants, base on the conditions stated above

$Quadrant\ IV = (5, -3)$ is correct

$Quadrant\ I = (9, 11)$ is correct

$Quadrant\ II = (-1, 3)$ is correct

$Quadrant\ III = (-2, -4)$ is correct

$Quadrant\ II = (-4, -8)$ is incorrect

Find the inverse of the function f(x) = 5/6x +10

UkoKoshka [18]

Answer:

$\displaystyle f^{-1}(x)=\frac{6x-60}{5}$

Step-by-step explanation:

<u>Inverse function</u>

Given the function

$\displaystyle f(x)=\frac{5}{6}x+10$

We find its inverse following the procedure below:

Set y=f(x)

$\displaystyle y=\frac{5}{6}x+10$

Multiply by 6:

$6y=5x+60$

Operate:

$5x=6y-60$

Solve for x:

$\displaystyle x=\frac{6y-60}{5}$

Swap variables:

$\displaystyle y=\frac{6x-60}{5}$

Make the new y the inverse function:

$\boxed{\displaystyle f^{-1}(x)=\frac{6x-60}{5}}$

This is the inverse function

Which of the following is used to name a segment that has an endpoint at point A and another endpoint at point B?

MakcuM [25]

You would write AB with a horizontal line segment over the letters A and B

So you would write this $\overline{AB}$

If you cannot draw that on your computer, then I would stick to saying "segment AB".
