Answer:
[tex]\boxed{-\frac{7}{12} }[/tex]
Step-by-step explanation:
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
→ Make both denominators the same
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}[/tex]
→ Convert mixed number into improper fraction
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}[/tex]
→ Do the -16 + 9 and leave 12 as the denominator
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}[/tex]
The required simplification o f[tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12
To simplify -1 1 / 3 plus 3 / 4 into fraction form.
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions constituting the Whole. And it is represented as a / b, where a = numerator and b = denominator.
Since the given problem is
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
We need to simplified it into fraction form like a / b.
[tex]=-1\frac{1}{3}+\frac{3}{4} \\= -2/3 + 3/4[/tex]
= ( -8 + 9 ) / 12
= -1 / 12
Thus, The required simplification of [tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12.

The fuel for a chain saw is a mix of oil and gasoline. The label says to mix 3 ounces of oil with 5 gallons of gasoline. How much oil would you use if you had 120 gallons of gasoline?
Answer:
120 gallons of gasoline needs 180 ounces of oil
Step-by-step explanation:
Since the label for the chain saw reads to mix 3 ounces of oil with 5 gallons of gasoline, it means we have a ratio of 3 ounces of oil to 5 gallons of gasoline. That is
3 ounces of oil = 5 gallons of gasoline
Using the the unity method, by dividing both sides by 5,
3/5 ounces of oil = 1 gallon of gasoline.
So, for 120 gallons of gasoline, we have
120 × 1gallon of gasoline = 120 × 3/5 ounces of oil
So, 120 gallons of gasoline = 60 × 3 ounces of oil
So, 120 gallons of gasoline = 180 ounces of oil
So, 120 gallons of gasoline needs 180 ounces of oil

Answer:
The values of k that make the given equation having imaginary roots are:
k < -18, or (-∞,-18).
Step-by-step explanation:
Nature of the Roots of a Quadratic Equation
The standard representation of a quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The expression:
[tex]d=b^2-4ac[/tex]
Is called the discriminant. The discriminant determines the nature of the roots of a quadratic equation as follows:
If d=0, there is only one real root.
if d>0, there are two different real roots
if d<0, there are two different imaginary (complex) roots
We are given the equation:
[tex]-2x^2+12x+k=0[/tex]
Comparing with the standard quadratic equation, we have:
a=-2, b=12, c=k
Calculating the discriminant:
[tex]d=12^2-4(-2)k[/tex]
[tex]d=144+8k[/tex]
If the equation has imaginary roots, then d<0, thus:
144 + 8k < 0
Subtracting 144:
8k < -144
Dividing by 8:
k < -18
The values of k that make the given equation having imaginary roots are: k < -18, or (-∞,-18).

every five years in march, the populations of a certain town is recorded. In 1995, the town had a populations of 4,500 people. From 1995 to 2000, the population increased by 15%. From 2000 to 2005, the population decreased by 4%. What was the town's population in 2005.
Answer:
population= 4968
Step-by-step explanation:
15/100= 0.15
1+0.15= 1.15
1.15 x 4500= 5175
4/100= 0.04
1-0.04= 0.96
0.96 x 5175= 4968

O A. $437.50
O B. $756.92
O C. $563.66
D. $587.50
Answer:
hope that helps
Step-by-step explanation:
Hi I had the same question on my test and the answer is c or b
The solution is, The initial payment will be $437.50.
Here, we have,
given that, Steven has obtained a $105,000 5/1 30-year ARM at 5%. During the first 3 years, he has an option of paying interest only.
so, we get,
Steven has obtained a $105,000, 5/1 30-year ARM at 5%.
During the first 3 years, he has an option of paying interest only.
So, it is simple interest.
Simple interest is given as :
I = p*r*t/100
here, p = 105000
r = 5%
t = 30
Putting values in formula:
= $157500
As this is interest for 30 years or 360 months.
So, for initial interest we will divide the interest with 360.
$157500/360
≈$437.50
Therefore, the initial payment will be $437.50

The function 56 – 4y = –5x can be used to determine the total amount of money in a coin jar, y, after money isadded for x days. What is the rate of change in dollars with respect to the number of days?
Answer:
$1.25 dollars per day added to the coin jar
Step-by-step explanation:
the given equation is: 56 – 4y = –5x
we can rewrite it:
4y = 56 + 5x
y = (56 + 5x) / 4
y = 14 + ⁵/₄x
the slope of the equation is ⁵/₄, which gives us how much money is added into the coin jar every day. We can write ⁵/₄ as 1.25 or $1.25 dollars per day added to the coin jar
(40, 3,000) and (60, 4,000)
find the slope of the line that passes through
Answer:
slope of the line is 50
Step-by-step explanation:
The slope of a line (gradient) is determined by the rise/run so
(y2 - y1) / (x2 - x1)
We simply substitute in our coordinates and solve. So:
(4000 - 3000) / (60 - 40)
= 1000 / 20
= 100/2 = 50
Gradient is 50

pls fast I need the answers for these I swear I'll make you the brainliest.
Answer:
Q1. 1050 miles
Q2. 1h 30m
Step-by-step explanation:
Q1. 1h = 300 miles
3[tex]\frac{1}{2}[/tex]h = 3.5 × 300 miles
= 1050 miles
Q2. 68km = 1h
102km = [tex]\frac{102}{68}[/tex] × 1h
= 1.5h
= 1h 30m

It is currently 84 degrees outside. If the temperature drops 2 degrees every hour, what equation
represents the temperature () after any number of hours (x)?
Answer:
[tex]T(x)=84-2x[/tex]
Step-by-step explanation:
Linear Modeling
The initial temperature outside is 84 degrees.
We are told the temperature drops 2 degrees every hour.
Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.
That drop is subtracted from the initial temperature to produce the linear model as follows:
[tex]\mathbf{T(x)=84-2x}[/tex]
This is the linear equation that represents the described situation.
What is the solution for x in 5x - 2 + 2x = 7x - 2?
help me plzzzzzzzzzzzzzz
Write an equation that represents the function. (linear equations)
Answer:
y = 2x + 2
Step-by-step explanation:
First solve for the slope using [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]\frac{8-2}{3-0}[/tex] = 2
Plug the slope into the slope intercept form equation y = mx + b
y = 2x + b
To solve for b, plug in any (x, y) point on the table.
2 = 2(0) + b
2 = b
Now you can plug the b value into your equation.
y = 2x + 2
