Solve the formula −4x+y=−6 for y.
Answer:
y=4x-6
Step-by-step explanation:
The formula for y is -6+4x from the equation −4x+y=−6.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is −4x+y=−6
Minus four times of x plus y equal to minus six.
We need to solve the formula for y.
In the given equation x and y are the variables.
Isolate the variable y by add 4x on both sides of the equation
y=-6+4x
Hence, the formula for y is -6+4x from the equation −4x+y=−6.

Step-by-step explanation:
in order to compare all the numbers, we have to express them all in the same form to compare them easily, we will choose to convert all of them to decimal form:
20% = 20/100 = 0.2
1/3 = 0.33333
3.4 x 10⁻¹ = 0.34
-5/2 = -2.5
comparing all these numbers, it is now clear that in decending order:
0.34 > 0.33333 > 0.2 > -2.5
or
3.4 x 10⁻¹ > 1/3 > 20% > -5/2

Find the equation of the line in slope-intercept form through (−5, 6) with slope = 3
Answer:
The answer is
[tex] \huge y = 3x + 21[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (−5, 6) and slope = 3
The equation of the line is
[tex]y - 6 = 3(x + 5) \\ y - 6 = 3x + 15 \\ y = 3x + 15 + 6[/tex]
We have the final answer as
[tex]y = 3x + 21[/tex]

How many times do you need to regroup to add 873 + 465 ? Explain .
Answer:
2
Step-by-step explanation:
To find the answer to this question, we need to add the numbers according to their place. Etc if 1 and 4 are together in a hundreds place, we add them together. If both numbers add up together results in a number bigger than 9, we have to regroup.
First, let us find the ones place.
3+5=8
Since the result is not more than 9, we do not have to regroup.
Secondly, we find the tens place.
7+6=13
Since the result is more than 9, we have to regroup.
Regrouping counter:1
Thirdly, we find the hundreds place.
8+4=12
Regrouping counter:2
Hence, your final answer is 2.
The number of times we need to group when summing 873 and 465 is 2.
During addition of two numbers, values are added based on their place values, such that digits with the same place value are added together.
The highest single value that can be obtained when summing values without needing to regroup is 9.
Hence, each time two digits are added such that the value of the sum exceeds 9, then regrouping is required.
Adding 873 + 465
H __ T __ U
8 __ 7 __ 3
4 __ 6 __ 5
(3 + 5) = 8 ( NO NEED TO REGROUP)
7 + 6 = 13 (WE NEED TO REGROUP) SUM exceed 9
(8 + 4 + 1) = 13 (WE NEED TO REGROUP) SUM exceed 9
Hence, the number of times we need to regroup is 2.

Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{ - 2 + 3}{8 - 4} [/tex]

Suppose that when a fabric production process is in control, the number of flaws in a piece of fabric of length l yards has a Poisson distribution with mean (.02)l. Suppose that periodically a length of fabric of 10 yards is inspected and the flaws are counted. If there are too many flaws, say more than k, the process will be presumed to be out of control, and stopped, and fixed. What should k be such that the probability of stopping the process when it is really in control is at most 5%
Answer:
Answer is attached below
Step-by-step explanation:
A length of fabric sampled = 10 yards
number of flaws in a piece of fabric having length = l yards
Poisson distribution mean = 0.02l
If the flaws are > k = process out of control hence would be stopped and fixed
Calculate The value of K such that the probability of stopping the process when it is really in control is at most 5%
using Poisson distribution

For what values of the variable does each of the following expressions make sense? We call the set of this values the domain of the expression. \sqrt{4-6a}
Given:
The expression is [tex]\sqrt{4-6a}[/tex].
To find:
The domain of the expression.
Solution:
We have,
[tex]\sqrt{4-6a}[/tex]
We know that, the square root is defined for only non-negative values. So,
[tex]4-6a\geq 0[/tex]
[tex]4\geq 6a[/tex]
Divide both sides by 6.
[tex]\dfrac{4}{6}\geq a[/tex]
[tex]\dfrac{2}{3}\geq a[/tex]
Thus, the value of variable less than [tex]\dfrac{2}{3}[/tex] make any sense.
Therefore, the domain of the given expression is [tex](-\infty,\dfrac{2}{3}][/tex].
The domain of a function is the set of input values the function can take
The domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]
The expression is given as:
[tex]\mathbf{\sqrt{4 - 6a}}[/tex]
Set the radicand to 0
[tex]\mathbf{4 - 6a = 0}[/tex]
Add 6a to both sides
[tex]\mathbf{6a = 4}[/tex]
Divide both sides by 6
[tex]\mathbf{a = \frac 23}[/tex]
This means that, the value of a must not be greater than 2/3.
Hence, the domain of the expression is: [tex]\mathbf{(-\infty, \frac 23]}[/tex]
