f(x)=|x+3| vertical stretch by factor of 4
The image of the function after it is vertically stretched is f'(x) = 4|x + 3|
How to determine the equation of f(x) after the transformation?The function is given as
f(x) = |x + 3|
The transformation is given as
Vertical stretch by a factor of 4
This implies that we stretch the function f(x) by a factor of 4
This transformation is represented mathematically as
(x, y) = (x, 4y)
So, we have
f'(x) = 4 * f(x)
So, we have the following equation
f'(x) = 4 * (|x + 3|)
Remove the bracket
So, we have
f'(x) = 4 * |x + 3|
Evaluate the products
So, we have
f'(x) = 4|x + 3|
Hence, the equation of f'(x) is f'(x) = 4|x + 3|

Why can't I see my answer?
Jessica is trying to save money to set aside for emergencies. she already has $75 and she earns $9 per hour at her family job. how many hours will she need to work to earn at least $500?
Answer:
Either 55.56 or 47.222 hours, depending on how the qyuestion is interpreted. The first answer assumes that Jessica's existing savgings of $75 is not available for emergencies.
Step-by-step explanation:
The question is difficult to answer. It doesn't specify that the $75 counts agains the $500. It simply asks how many hours of work does she need to earn $500.
Jessica is paid $9/hr, so her earnings (y, in $) are described by the formula: x hours at :
y = ($9/hr)*x
If we set y = $500:
$500 = ($9/hr)*x
x = $500/($9/hr)
x = 55.56 hours.
However, if we set y = $500 - $75, the Jessica only needs to work:
$425 = ($9/hr)*x
x = $425/($9/hr)
x = 47.222 hours
Greg is at his house he gets in his car drives north 8. 9 miles and stops at a store then he turns around and drives south 7. 7 miles to his friends house how far is the friends house from Greg’s houses?
His friend's house is 1.2 miles away from his house.
How do you know his friend's house is 1.2 miles away from his house?Well, the solution to this math problem is very simple. We just need to remove a number away from another. In other words, we only need to do some subtraction.
Subtraction is one of four main arithmetic operations in which we use to take away a number or an amount from another number or amount. Remember that the commutative law doesn't apply to subtraction, so we really need to be careful to pick what number is subtracted by the other number.
The distance from Greg's house to the store is 8.9 miles away. That's the number that is going to be subtracted. His friend's house is 7.7 miles away from the store. This is the number that we're going to subtract from the previous number. Mathematically, we can express this as:
8.9 - 7.7 = 1.2
We're left with 1.2, which is the distance in miles from Greg's house to his friend's house.

What is meant by differential equation?A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.
A differential equation in mathematics is an equation that includes one or more functions and their derivatives. The rate of change of a function at a place is determined by the derivatives of the function. It is mostly employed in disciplines like physics, engineering, biology, and others.
There exists at least a couple of ways to work this. One exists to write the equation for the distance between the cyclists and differentiate it.
d² = (3900 + 32t)² + (5200 + 24t)²
simplifying the above equation, we get
(2d)d/dt = 2(3900 + 32t)(32) +2(5200 + 24t)(24)
At t = 0,
dd/dt = (32·3900 + 24·5200)/√(3900² + 5200²)
simplifying the above equation, we get
= (124800 + 124800)/√(15210000 + 27040000)
= 249600/6500 = 38.4 meters per second

You contact an economist who believes there is a 20%probability the economy will remain strong, a 60% probability the economy will grow at a moderate pace, and a 20% probability theeconomy will slip into recession. What is the expected profit from this investment?The expected profit is $(Type an integer or a decimal.)
Answer:
6000
Explanation:
The expected profit from the investment can be calculated as the multiplication of each possible profit or loss by their respective probability.
Therefore, the expected profit is equal to:
E = 50,000(0.2) + 10,000(0.6) + (-50,000)(0.2)
E = 10,000 + 6,000 - 10,000
E = 6,000
Because there is a 20% of probability to win $50,000 (economy remain strong), there is a 60% of probability to win $10,000 (economy grows at a moderate pace), and there is a 20% of probability a loss of $50,000 (the economy goes into recession).
Therefore, the expected profit from this investment is:

points per dollar spent on flights, two points per dollar spent at hotels, and one voint per

14,660 points. The amount of money spent on flights was $140 more than twice the amount
of money spent on hotels. Find the amount of money spent on each type of purchase.
By the concept of linear equation :
$1,500 was spent on flights,
$680 was spent on hotels,
$7,300 was spent on other purchases.
What are linear equations?An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Ax+By=C represents a two-variable linear equation in its standard form. As an illustration, the conventional form of the linear equation 2x+3y=5 It is rather simple to locate both intercepts when an equation is stated in this way (x and y). For the purpose of resolving systems involving two linear equations, this form is also highly helpful.
Given:
Flights: 4 points per dollar
Hotels: 2 points per dollar
Other: 1 point per dollar.
Total spent = $9,480
Points earned = 14,660
Let
x = money spent on flights
y = money spent on hotels
z = money spent on other purchases.
Because the money spent on flights was $140 more than twice the money spent on hotels, therefore
x = 2y + 140 (1)
Total charges were $9,480, therefore
x + y + z = 9480 (2)
Total points earned was 14,660. Therefore
4x + 2y + z = 14660 (3)
Subtract (2) from (3).
4x + 2y + z - (x + y + z)
= 14660 - 9480
3x + y = 5180 (4)
Substitute (1) into (4).
3(2y + 140) + y = 5180
7y + 420 = 5180
7y = 4760
y = 680
From (1), obtain
x = 2y + 140
= 2(680) + 140
= 1500
From (2), obtain
z = 9480 - (x + y)
= 9480 - (1500 + 680)
