Write a function g whose graph is a vertical stretch by a factor of 3 of the graph of f(x)=|x|-5. g(x)=
Answers
Answer:
See belowStep-by-step explanation:
A vertical stretch by a factor of 3 of the graph of f(x) will result in:
g(x) = 3 f(x)This gives us:
g(x) = 3( |x| - 5) = 3|x| - 15The function g(x) after a vertical stretch by a factor of 3 can be defined as follows:
g(x) = 3(|x| - 5)
To create a function g(x) that is a vertical stretch by a factor of 3 of the graph of f(x) = |x| - 5, you can simply multiply the entire function f(x) by 3.
This will stretch the graph vertically while maintaining the same shape.
Therefore, the function g(x) can be defined as follows:
g(x) = 3(|x| - 5)
This function takes the absolute value of x, subtracts 5, and then multiplies the result by 3, resulting in a vertical stretch of the graph of f(x).
The vertical stretch by a factor of 3 means that the y-coordinates of all points on the graph are multiplied by 3, making the graph taller compared to the original f(x) graph.
Hence the function g(x) after the vertical stretch is g(x) = 3(|x|-5).

Step-by-step explanation:
Answer:
Distance ran on Tuesday: 297 miles

Andrew owns a plumbing company .the table shows the total amount charged based on the number of hours it takes to complete a job . Which equation best represents this situation?
Answers
Andrew's charges is an illustration of a linear function
The equation that represents the situation is [tex]\mathbf{y = 12x +45}[/tex]
From the table (see attachment), we have the following points
(x,y) = (1,57) and (2,69)
Start by calculating the slope (m)
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 -x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{69 - 57}{2 -1}}\\[/tex]
Simplify fraction
[tex]\mathbf{m = \frac{12}{1}}[/tex]
Divide
[tex]\mathbf{m = 12}[/tex]
The equation is then calculated using:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
So, we have:
[tex]\mathbf{y = 12(x - 1) + 57}[/tex]
Open brackets
[tex]\mathbf{y = 12x - 12 + 57}[/tex]
Evaluate like terms
[tex]\mathbf{y = 12x +45}[/tex]
Hence, the equation that represents the situation is [tex]\mathbf{y = 12x +45}[/tex]

Answer:
Equity
Step-by-step explanation:
A person puts into their relationship is proportional to what they feel they receive; this balance is called equity.
What is the relationship?The happiest, most enduring relationships are between best friends, They relish each other's company, trust on one another for love and attention, devote their free time apart, and have a lot of similarities.
A situation when people's benefits from relationships are inversely correlated with their contributions. These consequences don't necessarily have to be equal.
A person who is firmly attached has a strong feeling of merit and anticipates that most others will be receptive and sympathetic.
Because it fosters familiarity—which increases attraction—proximity counts in the attraction process. The probability that we will become interested to someone simply increases when we are in their presence or are exposed to them frequently.

How do you factor an expression to the 4 exponent.
Answers
Answer:
We can factor a difference of fourth powers (and higher powers) by treating each term as the square of another base, using the power to a power rule. For example, to factor x4 - y4, we treat x4 as (x2)2 and y4 as (y2)2. Thus, x4 - y4 = (x2)2 - (y2)2 = (x2 + y2)(x2 - y2) = (x2 + y2)(x + y)(x - y).
Answer: How do you factor variables with exponents? To do this, take the greatest common factor of the numbers and the smallest exponent of each variable. 2. Divide the original expression by the greatest common factor. To do this, divide the coefficients, and subtract the exponents of the variables.
Explanation: Expressions with fractional or negative exponents can be factored by pulling out a GCF. Look for the variable or exponent that is common to each term of the expression and pull out that variable or exponent raised to the lowest power. These expressions follow the same factoring rules as those with integer exponents.
