Answer:
[tex]\frac{-5}{12}[/tex]
Step-by-step explanation:
[tex]\frac{-3}{4}[/tex] - [tex]\frac{-1}{3}[/tex] Subtracting a negative number is the same as adding a positive
[tex]\frac{-3}{4}[/tex] + [tex]\frac{1}{3}[/tex] Rewrite each fraction with a common denominator. Let's use 12 as our new denominator.
[tex]\frac{-3}{4}[/tex] = [tex]\frac{-9}{12}[/tex] multiple the top and the bottom of the first fraction by 3 to get the equivalent fraction [tex]\frac{-9}{12}[/tex]
[tex]\frac{1}{3}[/tex] = [tex]\frac{4}{12}[/tex] Multiple the top and bottom of the first fraction by 4 to get the equivalent fraction [tex]\frac{4}{12}[/tex].
Now, add the two fractions
[tex]\frac{-9}{12}[/tex] + [tex]\frac{4}{12}[/tex] = [tex]\frac{-5}{12}[/tex] The denominator stays the same and you add the numerators.

Sue wrote a double fact. It has a sum less than 10 and greater than 4. The addends are each less than 5. What fact might she have written?
When Sue wrote a double fact. It has a sum less than 10 and greater than 4. The addends are each less than 5, the numbers that she wrote include 4+4 and 3+3.
How to illustrate the information?It is given that the sum is greater than 4 and smaller than 10.
If the sum is less than 10 and greater than 4 that limits you to 5,6,7,8,9
It should be noted that 5+5 is 10, and the sum has to be lower then 10.
The addends are less than 5 so it could be 4+4, 4+3, 4+2, 4+1
This shows that Sue might have written 5,6,7, or 8.

A bag of sand originally weighing 144 lb was lifted at a constant rate. As it rose, sand also leaked out at a constant rate. The sand was half gone by the time the bag had been lifted to 18 ft. How much work was done lifting the sand this far? (Neglect the weight of the bag and lifting equipment.)
Using a linear function and the work integral, it is found that the work that was done lifting the sand this far is of 944 ft-lb.
What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.For the weight of the bag of sand in this problem, we have that:
The initial weight of the bag was of 144 lb, hence the y-intercept is of b = 144.When the bag had been lifted 18 ft, 0.5 x 144 = 72 lb were gone, that is, 4 lb were gone for each ft the bag was lifted, hence the slope is of m = -4.Hence the weight of the bag after being lifted x feet is given by:
W(x) = 144 - 4x.
What is the work of a function?The work realized for a function f(x) in an interval [a,b] is given by the following integral:
[tex]W = \int_{a}^{b} f(x) dx[/tex]
For this problem, the function and the bounds of the interval are given as follows:
f(x) = 144 - 4x.a = 0, b = 18.Hence the work is given by:
[tex]W = \int_{a}^{b} (144 - 4x) dx[/tex]
W = 144x - 2x², from x = 0 to x = 18.
Applying the Fundamental Theorem of Calculus:
W = 144(18) - 2(18)² - 144(0) + 2(0)² = 1944 ft-lb.
The work that was done lifting the sand this far is of 944 ft-lb.

In a game experience, the level of monsters, L, is measured by the formula L= 250M E, where M=number of monsters and E=experience of monsters. Solve the formula for E
The formula for E is given as E = L/250M
According to the question we have been given that the level of monsters is measured by as follows
L = 250M E (1)
where , M = number of monsters
E = experience of monsters.
Now we need to find the formula for E. For that we will solve equation (1) for E .
L = 250M E
Dividing both the sides by 250M we get
L/250M = E
or, E = L/250M

The solution by using the quadratic formula is,
x = 4 + 2√6 i / 4 and x = 4 - 2√6 i / 4
What is Quadratic formula?
To solve a quadratic equation ax²+ bx + c = 0 , we use the quadratic formula,
x = - b ± √b² - 4ac / 2a
The given expression is;
- 2x² + 4x = 5
Now, The given equation is solve by using Quadratic formula as;
- 2x² + 4x = 5
Move terms to the left side
- 2x² + 4x - 5 = 0
- ( 2x² - 4x + 5 ) = 0
2x² - 4x + 5 = 0
Compare with quadratic equation ax²+ bx + c = 0 we get;
a = 2, b = -4, c = 5
Since, Quadratic formula is,
x = - b ± √b² - 4ac / 2a
Hence, Substituting all the values of a, b and c in quadratic formula we get;
x = - (-4) ± √(-4)² - 4*2*5 / 2*2
x = 4 ± √16 - 40 / 4
x = 4 ± √-24 / 4
x = 4 ± 2√-6 / 4 ( Since, i = √-1 )
x = 4 + 2√6 i / 4 and x = 4 - 2√6 i / 4
So, The solution by using the quadratic formula is,
x = 4 + 2√6 i / 4 and x = 4 - 2√6 i / 4

A ball is thrown with an initial height of 4 feet with an initial velocity of 36 ft/s.
The values of t for which the ball's height is 16 feet are 1.84s and 0.41s
From the question, we are to determine all values of t for which the ball's height is 16 feet
From the given information,
The equation that represents the ball's height (in feet) after t second is
h = 4 + 36t - 16t²
To determine all values of t for which the balls height is 16 feet, we will put h = 16 in the equation
That is,
h = 4 + 36t - 16t² becomes
16 = 4 + 36t - 16t²
Rearranging
16t² - 36t + 16 - 4 = 0
16t² - 36t + 12 = 0
Divide through by 4
4t² - 9t + 3 = 0
Solve the quadratic equation using the general formula
t = [-b±√(b²-4ac)]/2a
a = 4, b = -9, c = 3
t = [-(-9)±√((-9)²- 4(4)(3))]/2(4)
t = [9±√(81- 48)]/8
t = [9±√(33)]/8
t = [9±5.74]/8
t = [9+5.74]/8 or [9-5.74]/8
t = 14.74/8 or 3.26/8
t = 1.84 or 0.41
Hence, the values of t for which the ball's height is 16 feet are 1.84s and 0.41s

How to resolve a system of equation by algebra methods
Herein we find a system formed by one linear equation and one nonlinear equation (quadratic equation). First, we equalize the two equations to eliminate the variable y:
2 · x² - 5 · x - 7 = 2 · x + 2
2 · x² - 7 · x - 9 = 0
2 · [x² - (7 / 2) · x - 9 / 2] = 0
2 · (x - 9 / 2) · (x + 1)
There are two solutions to x: x₁ = 9 / 2, x₂ = - 1. And the solutions for y are:
x₁ = 9 / 2y₁ = 2 · (9 / 2) + 2
y₁ = 11

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=45(0.974)^x
Given function y =45(0.974)ˣ is a function of exponential decay and percentage rate of decrease is 2.6%.
What is an exponential function?The exponential function is an function f(x) = a(b)ˣ
a = initial amount when x= 0
b= base that is multiplied and it is greater than 0
And x is the variable in the exponent
When b> 1 , the values of this function goes up and up and then this function shows exponential growth.
When 0< b< 1, the values of this function becomes smaller as x increases then this function shows exponential decay.
And r is the percentage rate of change where b =r +1
Given function is y = f(x) = 45(0.974)ˣ
When we compare it with standard function f(x) = a(b)ˣ
we get a = 45 and b =0.974
As b is between 0 and 1 in this case, therefore this function is exponential decay.
b =r+ 1
therefore r = b-1 = 0.974-1 = -0.026
converting 0.026 to percentage we get -0.026*100= -2.6% ( negative sign shows decrease)
Therefore, we can say that the given function represents exponential decay function and rate of decrease is 2.6%

A die is rolled twice. What is the probability rolling a 3 first, followed by rolling an even number? Leave your answer as a reduced fraction.
The probability of rolling a 3 first, then an even number, is 1/12.
What do we mean by probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how likely they are. Statistics is the study of events governed by probability.So, in the given situation the first roll has no effect on the second roll because they are separate events.
Because they are independent, the probabilities of the two events can be multiplied.
The probability of getting a 3 is 1/6.The probability of getting an even number is 1/2 (2, 4, 6).Now, we will multiply the two probabilities as follows:
1/6 × 1/2 = 1/12Therefore, the probability of rolling a 3 first, followed by rolling an even number is 1/12.
