What is the solution to the equation below? (round your answer to two decimal places.)ln(x - 5) = 0.4?

1 answer:

3 0

First, you add 5 to the answer given, then you would end up with the value of X, x= 5.4 (the answer to two decimal places is 5.40)

This is basically doing the opposite of what the number's sign is. for example:

x+7=14, you would subtract 7 from the answer (14) and you would find the variable (x) that would mean that x=7.

This also applies for more complex equations like:

y x 12= 24

You can find the answer to this by dividing 24 (the answer given) by 12, which gives you 2. That would mean y=2

You can also check yourself with these equations by replacing the answer you got for the variable (the letter in the equation)

2 (y) x 12 = 24 y=2
5.4 (x) - 5 =0.4 x=5

Answer:

-a + 7b

Step-by-step explanation:

This problem is asking you to simplify the equation.

In order to do this, we will combine like terms (like terms are terms that share the same variable and/or exponent).

So we will combine 3a and -4a to get -1a or just -a, and now we'll combine 5b and 2b to get 7b.

So all together we have -a + 7b.

Hope this helps you :)

Answer:

1. D

2. F

3. F

4. C

5. F

6. B

Step-by-step explanation:

1. To find the slope, take two points from the table (in this case I'll use points (-3, 7) and (-1, 4)) and put them into the expression: $\frac{y2-y1}{x2-x1}$

$\frac{4-7}{-1-(-3)}$

Solve:

4 - 7 = -3

-1 - (-3) = -1 + 3 = 2

The slope is - $\frac{3}{2}$

2. I used the same process I used in number 1 using the points (-2, 4) and

(1, -1)

3. The slope of both equations represents how much each t-shirt was sold for. This means that whichever equation has a higher slope made greater profits. The slope of store B is 3.75 - we know this because the equation given is in y = mx, where m is the slope. To find the slope of store A, use the method I used in question 1 using two points from the graph ( I used points (0, 0) and (10, 40)). The slope of store A is 4, which is greater than 3.75, meaning that Store A made a greater profit per t-shirt.

4. To find the slope and y-intercept of this equation, let's convert the equation to slope-intercept form, y= mx + b, where m is the slope and b is the y-intercept. To do this we have to isolate the y:

y + 9x = -6

Subtract 9x from both sides to isolate the y:

y + 9x - 9x = -6 - 9x

y = -6 - 9x

This equation can also be written as: y = -9x - 6

Now we can see that the slope is -9 and the y-intercept is -6.

5. Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Slope is also known as rise over run. Looking the graph, for every 2 points it decreases on the y-axis, it increases by 1 on the x-axis. This can be written as -2/1, or simply -2. To find the y-intercept, find the point on the graph where the line intersects the y-axis. In this case, it's at y = -1. Now that we know the values of our slope and y-intercept, we can put them into the equation:

y = mx + b

y = -2x - 1

6. The y-intercept represents the amount Alice will have to pay for the game center before she pays for any guests. This value is $100.
