What is the value of x in 5x - 4 = 7x + 8?
Answers
Answer:
x = -6
Step-by-step explanation:
To find the value of x in the given equation, we have to solve for x.
5x - 4 = 7x + 8
Add 4 to both sides.
5x = 7x + 12
Subtract 7x from both sides.
-2x = 12
Divide both sides by -2.
x = -6
So the value of x would be -6.

A: -6
SBS: 5x-4-7x=7x+8-7x -2x-4=8 -2x -4+4 --> 8+ 4-2x=12
(DIVIDE)

For problems 4-6, determine the outputs for the following inputs of the function: f(x) = -2x² + 12x-4 x=3 5) x=-4 6) x=0 For problems 7 & 8, write the equation of the line through the points given. 7) (-5,2) and (5,4) 8) (-3,8) and (1.-4)
Answers
For the function f(x) = -2x² + 12x - 4, we can find the outputs for specific inputs. When x = 3, the output is 14. When x = -4, the output is -84. When x = 0, the output is -4.
For finding the equation of a line passing through given points, the equation can be determined using the slope-intercept form, y = mx + b.
To determine the outputs of the function f(x) = -2x² + 12x - 4 for specific inputs, we substitute the given values of x into the function and calculate the corresponding outputs.
a) For x = 3: f(3) = -2(3)² + 12(3) - 4 = -18 + 36 - 4 = 14.
b) For x = -4: f(-4) = -2(-4)² + 12(-4) - 4 = -32 - 48 - 4 = -84.
c) For x = 0: f(0) = -2(0)² + 12(0) - 4 = 0 - 0 - 4 = -4.
Moving on to finding the equation of lines passing through given points:
7) The points given are (-5,2) and (5,4). We can calculate the slope (m) using the formula m = (y2 - y1) / (x2 - x1). Substituting the coordinates, we have m = (4 - 2) / (5 - (-5)) = 2 / 10 = 1/5. Using the slope-intercept form, y = mx + b, we can substitute one of the given points and the slope to solve for b. Let's use the point (5,4): 4 = (1/5)(5) + b. Simplifying, we find b = 4 - 1 = 3. Therefore, the equation of the line is y = (1/5)x + 3.
The points given are (-3,8) and (1,-4). Calculating the slope, m = (-4 - 8) / (1 - (-3)) = -12 / 4 = -3. Again, using the slope-intercept form, we substitute the point (1,-4) and the slope: -4 = (-3)(1) + b. Solving for b, we find b = -1. Hence, the equation of the line is y = -3x - 1.

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the scale factor?
a. 0.08
b. 1.08
c. 0.92
d. 8
Answers
The scale factor after one year of depreciation is 0.92.(option-c)
The depreciation rate of 8% per year means that the car loses 8% of its value each year. To find the scale factor, we need to determine how much of the original value remains after one year of depreciation.
If the car loses 8% of its value each year, then the remaining value after one year is:
100% - 8% = 92% of the original value
We can express this as a decimal by dividing 92% by 100%, which gives:
92%/100% = 0.92
This means that the value of the car is 0.92 times its original value after one year of depreciation.
We can also check our answer by calculating the value of the car after one year:
Value after one year = 0.92 * $15,000 = $13,800
This is the expected value of the car after one year of depreciation, which confirms that our scale factor of 0.92 is correct.
Therefore, the answer is (C) .

Write the complex number in standard form. (Simplify your answer completely.) (5+ √5) (6-√-10)
Answers
To write the complex number (5+√5)(6-√-10) in standard form, we simplify the expression by multiplying the terms and then combine the real and imaginary parts. The standard form of the complex number is 30 + 5√2.
To simplify the expression (5+√5)(6-√-10), we need to multiply the terms using the distributive property.
First, let's multiply the real parts:
5 * 6 = 30.
Next, we multiply the imaginary parts:
√5 * -√-10 = -√(5 * -10) = -√(-50) = -√(50)(-1) = -√(25 * 2)(-1) = -√25 * √2 * (-1) = -5√2.
Now, let's combine the real and imaginary parts to write the complex number in standard form:
(5+√5)(6-√-10) = 30 + 5√2.
Therefore, the complex number (5+√5)(6-√-10) can be written in standard form as 30 + 5√2. In standard form, the complex number is expressed as the sum of a real part and an imaginary part. The real part is 30, and the imaginary part is 5√2.

A store is designing the space for rows of nested shopping carts.
Each row has a starting cart that is `4` feet long, followed by the nested carts. (`0` nested carts means there's just the starting cart.)
• A row of `13` nested carts is `23.5` feet long.
• A row of `18` nested carts is `31` feet long.
Enter the appropriate label and scale for each axis, and drag the movable points to create a graph of the situation.
Answers
By creating a graph that shows the relationship between the number of carts and the space required, the store can better design the space for rows of nested shopping carts.
To design the space for rows of nested shopping carts in a store, a graph can be created that shows the relationship between the number of carts and the amount of space required.
This can be done by plotting the number of carts on the x-axis and the space required on the y-axis.The appropriate labels for each axis are "Number of Carts" for the x-axis and "Space Required" for the y-axis.
The scale for the x-axis would depend on the maximum number of carts that the store wants to accommodate, while the scale for the y-axis would depend on the amount of space that each cart takes up.
The movable points on the graph can be used to illustrate different scenarios.
For example, if the store wants to know how much space would be required for 50 carts, the movable point can be placed at 50 on the x-axis, and the corresponding space required can be read off the y-axis.
Similarly, if the store wants to know how many carts can be accommodated in a given amount of space, the movable point can be placed at the desired space on the y-axis, and the corresponding number of carts can be read off the x-axis.

Solve for the indicated variable
ab-ac= 2 for a
Answers
Given, the indicated variable is: ab - ac = 2, We have to solve the given equation for a. So the answer is a = 2/(b - c).
Let's do this: Factor out the a from the left-hand side of the equation.
Using the distributive property, we get: a(b - c) = 2
Now, we'll isolate a by dividing both sides by (b - c).
Thus, we get: a = 2/(b - c)
Therefore, the value of the variable a is 2 divided by the quantity of (b - c).
Let's have a look at the steps: ab - ac = 2
a(b - c) = 2
a = 2/(b - c). Hence, we have obtained the value of the variable a by solving the given equation.

Answers
The expected value of x is 750.5, rounded to 1 decimal place.
To calculate the expected value of x, we need to determine the probability distribution of x and then calculate the weighted average of x.
The probability of finding the golden ticket in the first seat cleaned is 1/1500, as there are 1500 seats and the ticket is equally likely to be in any of them.
Similarly, the probability of finding the ticket in the second seat cleaned is (1499/1500) * (1/1499) = 1/1500. The probability of finding the ticket in the third seat cleaned is (1499/1500) * (1498/1499) * (1/1498) = 1/1500, and so on.
From this pattern, we can observe that the probability of finding the ticket in the x-th seat cleaned is 1/1500.
Now, let's calculate the expected value of x:
E(x) = (1/1500) * 1 + (1/1500) * 2 + (1/1500) * 3 + ... + (1/1500) * 1500
E(x) = (1/1500) * (1 + 2 + 3 + ... + 1500)
E(x) = (1/1500) * [(1500 * 1501) / 2]
E(x) = (1501 / 2) = 750.5
Therefore, the expected value of x is 750.5, rounded to 1 decimal place.

consider the function h(x)= -2cos(8x-π/4)+5. what transformation results in j(x)=-2cos(8x-π/4)-5
Answers
The transformation from h(x) that gives j(x) is 10 units translation down
How to determine the transformation?The equation of the functions are given as
h(x) = -2cos(8x - π/4) + 5
j(x) = -2cos(8x-π/4) - 5
From the above equations, we can see that only the constant term of the equations are different
This means that the function h(x) is translated vertically to get the function j(x)
So, we simply subtract j(x) from h(x) to calculate the unit of translation
This is represented as
Units = j(x) - h(x)
This gives
Units = -2cos(8x - π/4) - 5 + 2cos(8x-π/4) - 5
Evaluate the like terms
Units = - 5 - 5
Evaluate the sum
Units = -10
This means that the transformation is 10 units translation downwards
