Step-by-step explanation:
The value of x in the given expression is -a/6
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 4 = 6x / a + 5
Solving for x, we get,
4 = 6x / a + 5
Subtracting 5 both the side,
6x / a = -1
Multiplying by a both the sides,
6x = -a
Dividing by 6 both sides,
x = -a/6
Hence, the value of x is -a/6

Write the sentence as an inequality. Three times a number r plus 8 is fewer than −12
Answer: [tex]3r+8<-12[/tex].
Step-by-step explanation:
It is given that three times a number r plus 8 is fewer than −12.
We need to write the sentence as an inequality.
Three times a number r = 3r
Times a number r plus 8 = 3r+8
Fewer than = less than = <
So, the inequality for the sentence "three times a number r plus 8 is fewer than −12" is
[tex]3r+8<-12[/tex]
Therefore, the required inequality is [tex]3r+8<-12[/tex].
The inequality that describes the sentence is:
[tex]3r + 8 < -12[/tex]
--------------------------------
3 times 1 is [tex]3 \times 1 = 3[/tex], 3 times 2 is [tex]3 \times 2 = 6[/tex], and so on, thus 3 times a number r is [tex]3 \times r = 3r[/tex].The plus word means that we have an addition operation, plus 8, thus [tex]3r + 8[/tex]Fewer than -12 means that the less than -12 completes the inequality, thus:[tex]3r + 8 < -12[/tex]
Which is the inequality that describes this situation.

Explain why the function is discontinuous at the given number
Answer:
left limit = 2 ≠ 1/2 = right limit
Step-by-step explanation:
A function is discontinuous if the limit of the function value approaching the point from the left is different than the limit approaching from the right.
Here, the left limit is 2 and the right limit is 1/2. The limits are different, which is why the function is discontinuous at x=-1.
Alice’s school has purchased a new $10,000 copier. The copier depreciates in value by 15% every year. The principal will replace the copier when it drops below 10% of its original value.

What is depreciation?The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation.
What is compound interest for depreciation?If the reduced value of the goods is compounded for fixed time then it is called compound depreciation.
Formula of compound interest for depreciation:
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
Where,
A= Final Amount
P = initial Principal
n = time in years
r = rate per annum
According to the question
New copier costs (p) = $10,000
depreciates in value every year (r) = 15%
The principal will replace the copier when it drops below 10% of its original value.
i.e Final amount should be less than [tex]$10,000 * \frac{10}{100}[/tex]
A is < $ 1000
Using compound interest formula :
[tex]A = P(1-\frac{r}{100} )^{n}[/tex]
[tex]1000 > 10000(1-\frac{15}{100} )^{n}[/tex]
[tex]0.1 > (0.85 )^{n}[/tex]
n ≈ 14.168
n = after 15years (next whole no)
Hence , The solution set for the inequality is (15, ∞).

14x-10=3 (4+x); solve for x
Answer:
x = 2
Step-by-step explanation:
So we are given the equation 14x - 10 = 3(4 + x) and we are asked to solve for x. To this, we will have to get x by itself on one side and a value on the other side.
14x - 10 = 3(4 + x)
Distribute the 3 on the right side.
14x - 10 = 12 + 3x
Add 10 to both sides.
14x = 22 + 3x
Subtract 3x from both sides.
11x = 22
Divide both sides by 11.
x = 2
So now we got the answer of x = 2.
I hope you find my answer helpful.
Answer:
x = 2
Step-by-step explanation:
14x - 10 = 3(4+x)
=> 14x -10 = 12 + 3x
=> 14x - 3x = 12 + 10
=> 11x = 22
=> x = 22/11
=> x = 2
