Multiple choice what is -1.8 - 3.9=
Answer:
1. -5.7
Step-by-step explanation:
When a negative number and another negative number are being added together (but this differs in multiplication and division though), the answer will always be negative, unless a greater positive (combination or single) number is being added to those, but in this case, it is just two negative numbers. What you can do here is add the absolute values of the negative numbers, which would be 1.8 + 3.9, since absolute values are always positive numbers. Once you add these values, which gives you 5.7, you make the answer negative, because before, you were adding negative numbers, so your answer would be -5.7.
Just so you can make sure your answers are correct for the next ones:
2. -2
3. -4.4

What expression is equivalent to 48+60
Answer:
48 + 60 is equivalent to 108
Step-by-step explanation:
Find the distance between the pair of points. (-4,-3) and (-4,-6)
[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]
For two given points, (x1,y1) and (x2, y2) the distance between the points can be calculated by,
Distance formula,
d=√((x2 - x1)²+(y2 - y1)²
Given points,
(x1, y1) = (-4, -3)(x2, y2) = (-4, -6)Put the values,
d = √(-4 + 4)² + (-6 + 3)²
d = √ 0 + (-3)²
d = √9
d = [tex] \pm[/tex] 3
But distance is always positive. Hence, the distance between the pair of points. (-4,-3) and (-4,-6) is 3 units.
Answer:
take -4 as x1 and minus 3as y1 again take minus 4 as x2 and minus 6 as y2
now

Suppose a single person facos a tax rate of 10% on income from 0-$10,000 and 12% on income from $10,000 to $40,000 and 22% on income
from $40,000 to $85,000. Rates continue to climb, with marginal rates of 24$, 32%, 35% and 37% for higher levels of income. What is the total
tax if you earn $57,703 year?
9514 1404 393
Answer:
$8494.66
Step-by-step explanation:
The total taxes due is the sum of the tax due in each bracket.
$10,000 × 10% + ($40,000 -10,000) × 12% + ($57,703 -40,000) × 22%
= $1000 + 3600 +3894.66 = $8494.66
The total income tax on $50,000 is $8494.66.

hi there please explain how to solve or factorise this as i dont know the formula plus how to do ?:)
(x^2+1)?
Steps:
Writing down the equation. x^2 + 1 = 0.Subtract 1 from both sides. x^2 = -1Square root (I am going to use the abbreviation sqrt) on both sides. x = sqrt (-1)sqrt (-1) is simplified as i (or imaginary number). Because of the sqrt, it would be plus or minus.(x+i)(x-i) is your answer. If you are in a lower math class (mentioning 10th grade or below), you should just put no solution.Hello,
We cannot factorize this binomial expression using normal factorization method.
if you have studied complex numbers method, then you can solve.
Here are the steps :-
[tex]{x}^{2} = (x)(x)[/tex]
[tex]→1 = (i)( - i)[/tex]
Now multiply,
[tex](x)(i) + (x)( - i) = (xi) - (xi) = 0[/tex]
[tex]→(x + i)(x - i)[/tex]
Therefore, the factors are (x+i)(x-i) :-
[tex]→ {x}^{2} = (x + i)(x - i)[/tex]

A new work truck sells for $55,000 and depreciates at $ -6,500 per year. Write a
linear function of the form y=mx+b to represent the value y of the vehicle x years
after purchase. Use your formula to find the value of the truck 5 years after
purchase.
per year.
Answer:
y = -6500x +55000$22,500 after 5 yearsStep-by-step explanation:
In the formula ...
y = mx + b
the value of m is the change per year, and the value of b is the initial value. Using the given information, the equation is ...
y = -6500x +55000
__
When x=5, the value is ...
y = -6500(5) +55000 = -32500 +55000 = 22500
The value of the truck after 5 years is $22,500.

7.50x - 6.25 = 26.25
Answer:
4 1/3
Step-by-step explanation:
7.50x-6.25=26.25
7.5x=26.25+6.25
=32.5
x=32.5÷7.5
=4 1/3
Answer:
4.33333333333 or 4 1/3
Step-by-step explanation:
Inverse operations
26.25 + 6.25 = 32.5
32.5 Divided by 7.50 = 4.33333333333
Answer = 4.33333333333
Solve for x
-4.5 = -0.5(x – 7.1)
Answer:
16.1
Step-by-step explanation:
- 4.5 = - 0.5 ( x - 7.1 )
Divide - 0.5 on both sides,
- 4.5 / - 0.5 = - 0.5 ( x - 7.1 ) / - 0.5
9 = x - 7.1
Add 7.1 on both sides,
9 + 7.1 = x - 7.1 + 7.1
16.1 = x
x = 16.1
Answer:
16.1

Step-by-step explanation:
I did the k12 quiz
The sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times 8/3 is 4 [tex]\frac{5}{9}[/tex].
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is 4 [tex]\frac{5}{9}[/tex] is the same as the sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times a number
Assume the number to be [x]. Then, we can write -
41/9 = 7/3 + 5x/6
41/9 - 7/3 = 5x/6
(41 - 21)/9 = 5x/6
20/9 = 5x/6
x = 20/9 x 6/5
x = 4/3 x 2
x = 8/3
Therefore, the sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times 8/3 is 4 [tex]\frac{5}{9}[/tex].
