Answer:
y + 5x + 8
Explanation:
Has three termscoefficient of 5constant of 8Move numbers or variable:
y + 5x + 8
Additional Information:
x + y + 1
This has three terms, coefficient of 1, constant of 1
Answer:
[tex]\huge\boxed{\bf\: x + 5y + 8}[/tex]
Step-by-step explanation:
We need to make an expression using the given conditions. Let's look at them in order.
Condition 1:
If the expression has three terms then let's take the three terms as, x, y & z. Therefore, the expression uoto now = x + y + z.
Condition 2:
Now, the expression has a term with coefficient = 5. Let's put 'y' with coefficient 5 since the second term has two blanks in the question. So, expression = x + 5y + z.
Condition 3:
The expression also has a constant 8. By substituting the value of 'z' with 8 (as 'z' is not given in the options), we get the final expression as → x + 5y + 8.

I'm going to discuss one way to do it, and then show a much better way.
If you attack the problem directly, there are 3 ways of placing just 1 day not being late
0.7 * 0.3 * 0.3 = .063
0.3 * 0.7 * 0.3 = .063
0.3 * 0.3 * 0.7 = 0.63
Making it on on time on two days gives you 3 equations as well
0.7* 0.7 * 0.3 = .147
0.7* 0.3 * 0.7 = .147
0.3 * 0.7 * 0.7 = .147
Making it on time all three days
0.7 * 0.7 * 0.7 = .343
If you add add these up, you should get 0.973
There is a better way. First calculate what happens if he is late all three days.
0.3 * 0.3 * 0.3 = 0.027 No on times (.7) anywhere.
If you take 0.027 away from 1, you get 0.973 That takes care of all the times he was on time. Much neater and easier, no?

A line has a slope of 2. It passes through the points (1, 2) and (3, y) . What is the value of y?
Answer:
Step-byThe equation of the line with slope 2 is y=2x+b, b is a constant which should be determined. The line passes via through points (1, 2) and (3,y)
(1, 2): 2=2+b --> b=0
So, the equation of the line is y=2x. Now, when x=3, y=6. So the line y=2x passes through points (1, 2) and (3, 6). (3,y)=(3, 6).-step explanation:
-7- -13 ( subtracting integers)
Answer:
Looking at the problem we come across one issue where we have two minus signs. However, this issue can be fixed because for example if we multiply -1 by -1 we would just get 1. Therefore these two minus signs cancel out and we put a plus sign so our problem becomes -7 + 13. Now we just combine and we get 6.

Determine the justification for the steps from the derivation of the quadratic formula. justification of step a: justification of step b:
The justification of step a is common denominator and the justification of step b is multiplication property of equality
How to determine the justifications?The equation is given as:
[tex]a(x + \frac{b}{2a})^2 = -c + \frac{b^2}{4a}[/tex]
Take the LCM
This gives
[tex]a(x + \frac{b}{2a})^2 = \frac{-4ac + b^2}{4a}[/tex]
The above represents a common denominator.
Multiply both sides by 4a
[tex]4a^2(x + \frac{b}{2a})^2 = -4ac + b^2[/tex]
The above represents the multiplication property

Tegan is checking her tax bill for the last year.
the tax rates were as follows:
•No tax on the first of £11,000 earnings
•earnings in excess of £11,000 and up to £43,000 taxed at a rate of 20%
•earnings in excess of £43,000 and up to £150,000 taxed at a rate of 40%
last year Tegan earned £48300 before tax
how much tax did she pay in total. please help give you brainiest.
A percentage is a way to describe a part of a whole. The total tax of Tegan's earnings will be £8,520(£6,400+£1,200).
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Since there is no tax for the first £11,000, therefore, the earnings which will be taxed,
£48,300 - £11,000 = £37,300
The amount of tax for the income of £11,000 to £43,000, will be,
20% of (£11,000 to £43,000)
= 20% × (£43,000 - £11,000)
= £6,400
The amount of tax for the income of £11,000 to £150,000, will be,
40% of (£43,000 to £48,300)
= 40% × (£5,300)
= £2,120
Hence, the total tax of Tegan's earnings will be £8,520(£6,400+£1,200).

The graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2 option (D) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function:
If we take the function:
[tex]\rm f(x) = \dfrac{1}{\left(x-1\right)\left(x-2\right)}[/tex]
At x = 1 and x = 2 the function will be not defined, so this region would be hollow and as we can see in the graph of a function.
The function is not defined at x = 1 and x = 2.
Thus, the graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2.
