2x + 6 = 0
Reorder the terms:
6 + 2x = 0
Solving
6 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 0 + -6
2x = 0 + -6
Combine like terms: 0 + -6 = -6
2x = -6
Divide each side by '2'.
x = -3
Simplifying
x = -3
Answer:
2x < 6
=> x < 6/2
=> x < 3

10.Mr. Vickers earns a 7.5% commission on his total sales. Last month, he had sales of
$54,620. How much commission did Mr. Vickers earn last month?
Answer:
4096.50, 4,096.50, $4,096.50, or $4096.5
Step-by-step explanation:
4096.5 percentage is the commission did Mr. Vickers earn last month.
Percentage:A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.Percentage formula = (Value/Total value) × 10
Example: 2/5 × 100 = 0.4 × 100 = 40 per cent
Based on the given conditions, formulate: 7.5% × 54620
Calculate the product or quotient: 4096.5

When the sun is 45 degrees above the horizon and a tree's shadow is 10ft long, how tall is the tree? *
5ft
7ft
10ft
15ft
Answer:
C
Step-by-step explanation:
Please refer to the attachment below.
So, we essentially have a 45-45-90 triangle.
In the 45-45-90 triangle, the two legs are equivalent.
Therefore, since one of the legs is 10ft, the other leg, the height of the tree, must also be 10ft.
Hence, our answer is C.

Billys empolyer for 65% of his annual health insurance permiu. Billy has the rest deducted equal amounts from his paycheck. If Billy has $105.73 withheld from his paychecks twice each month, how much dose his employrt contribute twards his health insuranceon an annual basis.
Answer:
His employer contributes with $4712.53 towards his health insurance on an annual basis.
Step-by-step explanation:
With the information provided, you know that Billy's employer pays 65% of his health insurance premium and you can subtract this from 100% to know the percentage that Billy has to pay:
100%-65%=35%
Also, the information states that Billy has $105.73 withheld from his paychecks twice each month and you can multiply this for 24 to find the total amount that he pays per year and that represents 35%:
$105.73*24=$2537.52
Finally, you can use a rule of three to found the amount that represents 65% which would be what his employer pays given that $2537.52 represent 35%:
2537.52 → 35%
x ← 65%
x=(2537.52*65)/35
x=$4712.53
According to this, the answer is that his employer contributes with $4712.53 towards his health insurance on an annual basis.

What is an equation of the line that passes through the points (6, -6) and (-6, -8)
Answer:
An equation of the line that passes through the points (6, -6) and (-6, -8) is [tex]\mathbf{y+6= \frac{1}{6}(x-6)}[/tex]
Step-by-step explanation:
We need to write an equation of the line that passes through the points (6, -6) and (-6, -8)
We would use point slope formula: [tex]y-y_1=m(x-x_1)[/tex]
where [tex]x_1=6, y_1=-6 \ and \ m \ is \ slope[/tex]
Finding slope using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
We have [tex]x_1=6, y_1=-6, x_2=-6, y_2=-8[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\\\Slope=\frac{-8-(-6)}{-6-6}\\Slope=\frac{-8+6}{-12}\\Slope=\frac{-2}{-12}\\Slope=\frac{1}{6}[/tex]
So, slope = 1/6
The required equation having [tex]x_1=6, y_1=-6 \ and \ m =\frac{1}{6}[/tex]
[tex]y-(-6)=\frac{1}{6}(x-6)\\y+6= \frac{1}{6}(x-6)[/tex]
An equation of the line that passes through the points (6, -6) and (-6, -8) is [tex]\mathbf{y+6= \frac{1}{6}(x-6)}[/tex]

10x + 12y = 300
10(12) + 12y = 300

12y = 180
y = 180 / 12
y = 15

Evaluate x+y when x=−4\5 and y=1\3. Write your answer as a fraction or mixed number in simplest form.
Answer:
When x=−4\5 and y=1\3 we get x+y = -7/15
Step-by-step explanation:
We are given :
x=−4\5 and y=1\3
We need to evaluate : x+y
Solving:
[tex]x+y\\=-\frac{4}{5}+\frac{1}{3}[/tex]
Taking LCM of denominators 5 and 3, we get 15
[tex]=\frac{-4*3+1*5}{15}\\=\frac{-12+5}{15}\\=\frac{-7}{15}[/tex]
So, when x=−4\5 and y=1\3 we get x+y = -7/15

Of the 2,374 pieces produced by a particular machine, 27 were defective. What
percent were defective? Round to the nearest hundredth of a percent.
Answer:
1.14%Step by step explanation
Step one:
The total pieced produces is 2374
total defective is 27
to find the percentage of the defective pieces, we would need to divide the total pieces of the defective by the total number of pieces produced by the machine and multiply the result by 100
Step two
% defecive= (27/2374)*100
% defecive= 0.0113*100
% defecive= 1.137%
To the nearest hundredth of a percent 1.14%
In a triangle, the base is increasing at a constant rate of 2.8 cm per second, while the height is decreasing at a constant rate of 0.7 cm per second. At the instant when the base of the triangle is 6 cm and the height of the triangle is 10 cm, what is the rate of change of the area of the triangle?
Answer:
Step-by-step explanation:
Area of a triangle = 1/2bh
b is the base
h is the height
dA/dt = dA/db * db/dt + dA/dh * dh/dt
h = 10cm
b = 6cm
dA/db = h/2 = 10/2
dA/db = 5cm
dA/dh = b/2
dA/dh = 6/2 = 3cm
db/dt = 2.8cm/s
dh/dt = 0.7cm/s
Substitutte into the formula;
dA/dt = 5(2.8) + 3(0.7)
dA/dt = 14 + 2.1
dA/dt = 16.1cm²/s
Hence the rate of change of the area of the triangle is 16.1cm²/s

Given that;
The functions are,
⇒ R (x) = 3x
⇒ g (x) = R(x) + 3
Now, We get;
⇒ g (x) = R(x) + 3
⇒ g (x) = 3x + 3
⇒ g (x) = 3 (x + 1)
Thus, The correct transformation of A (x) will produce the same graph as g(x) is,
