six subtracted from one-half a number is 12.
Answer:
Number is 36
Step-by-step explanation:
Let the number be x
one half of the number is [tex]\frac{1}{2} x[/tex]
6 subtracted from one half is 12, That is,
[tex]\frac{1}{2} x - 6 = 12\\\\\frac{1}{2}x = 12 +6 \\\\x = 18 \times 2 = 36[/tex]

A curve passes through the point ( 0 , 7 ) (0,7) and has the property that the slope of the curve at every point P P is twice the y y -coordinate of P P . What is the equation of the curve
Answer:
The equation for the curve is:
[tex]f(x) = 7*e^{2*x}[/tex]
Step-by-step explanation:
We know that for a curve defined as:
y = f(x)
The slope of the curve at the point x is:
y = f'(x)
where f'(x) = df(x)/dx
Here we know that we have a function that passes through the point (0, 7)
We also know that the slope of the curve at every point is twice the value of the y-coordinate. (remember that the y-coordinate is given by f(x))
Then we have two equations:
f(0) = 7
f'(x) = 2*f(x)
From the shape of the equation, we can assume than this is an exponential equation like:
[tex]f(x) = A*e^{k*x}[/tex]
Replacing that in the second equation, we get:
[tex]k*A*e^{k*x} = 2*A*e^{k*x}[/tex]
From that equation, we can conclude that k = 2
Then:
[tex]f(x) = A*e^{2*x}[/tex]
Now we can use the first equation:
f(0) = 7
With this, we can find the value of A.
[tex]f(0) = 7 = A*e^{2*0}\\7 = A*e^0 = A*1\\7 = A[/tex]
Then we can conclude that the equation for the curve is:
[tex]f(x) = 7*e^{2*x}[/tex]
Quantitative - Column chart
Quantitative - Line chart
Qualitative - Histogram
Qualitative - Pie chart
Answer:
A. Qualitative - Column chart
Step-by-step explanation:
Data could either be qualitative or quantitative. Quantitative data are usually given in a definite number, i.e it can be counted. While qualitative deals with characteristics, i.e it can be collected either by the use of questionnaires, or any similar method.
Therefore for the given question, the data survey is qualitative. And since the result would be presented as a graph showing the percentage users for each application, a column chart would be appropriate.
Thus for the data and its presentation, the answer is A. Quantitative - Column chart

Answer:
Mean number of holidays taken =26.6
Step-by-step explanation:
To find the mean,
We use Σfx/Σf
Σfx =150+234+189+84+0+60
=717
Σf= 6+9+7+3+0+2
=27
Σfx/Σf= 717/27

Find the function value f(-8)
f(x)=6x-1
Step-by-step explanation:
-8=6x-1
You will move the-8 to the right hand side which will become +8 and then you move+6x to the right hand side which will become -6x
-6x=-1+8
-6x=7
You will divide both sides by-6
-6x/-6=7/-6
x=7/-6

Find the LCM of the polynomials.
x² - x - 42
x2 + x - 56
Answer:
x^3+7x^2-50x-336 or (x-7)(x+6)(x+8)
Step-by-step explanation:
Factor each equation.
x^2-x-42= (x-7)(x+6)
x^2+x-56= (x-7)(x+8)
The common factor is (x-7), therefore the other factors of the expressions must multiply to find the common factor.
(x-7)(x+6)(x+8)=x^3+7x^2-50x-336.
How many solutions does this linear system have?
y=-1/2x+4
x + 2y = 8
one solution: (8,0)
one solution: (0,8)
no solution
O infinite number of solutions
Answer:
no solution
Step-by-step explanation:
__________
There are ''infinite number of solutions'' does this linear system have.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Linear systems are,
⇒ y = -1/2x + 4 ... (i)
⇒ x + 2y = 8 .. (ii)
Now, From equation (ii);
⇒ x + 2y = 8
⇒ 2y = - x + 8
⇒ y = - 1/2x + 4
Which is same as equation (i).
Hence, There are infinite number of solutions does this linear system have.

Find the value of y
A) 9.850
B) 18.610
C) 65.825
D) 125.365
Answer:
B) 18.610
Step-by-step explanation:
Using SOHCAHTOA (trig ratios), the tangent of 28° is the ratio of its opposite length to its adjacent.
in this scenario, the side opposite to 28°, and the side adjacent to it is 35°
tan 28° = y/35
Using inverse operations, multiply both sides by 35
y = 35 * tan 28
