(-6)(-2x – 4y); x = 1, y = 3
Answer:
First, you have to substitute your x and y.
This looks like
(-6)(-2 - 12) because you multiplied (-2)(1) and (-4)(3)
Then, you have to do what's in the parenthesis because of order of operations.
(-6)(-14)

What is greater 16/28 or 28/49
Answer:
They are equal.
Step-by-step explanation:
Step 1: Evaluate 16/28
16/28 = 0.571429...
Step 2: Evaluate 28/49
28/49 = 0.571429...
Step 3: Compare
0.571429... ? 0.571429...
0.571429... = 0.571429...
So 16/28 = 28/49

Given that f(x) = x2 + x and g(x) = 3x + 1, find the value of g(f(-2)).
Answer:
7Step-by-step explanation:
[tex]f(x) = x^2 + x\\g(x) = 3x + 1\\\\g(f(-2)) = ?\\f(-2) =?\\[/tex]
To find f(-2) , Substitute -2 for x in the given equation ;
[tex]f(-2)= (-2)^2 +(-2)\\f(-2) = 4-2\\f(-2) = 2[/tex]
To find g(f(-2)) ;
[tex]g(f(-2))\\f(-2) =2\\\\= g(f(-2)) = g(2)\\[/tex]
To find g(2) , substitute 2 for x in the given equation
[tex]g(x) = 3x+1\\g(2) = 3(2)+1\\\\g(f(-2)) = 6+1\\\\g(f(-2))=7[/tex]
Value of g(f(-2)) is equals to 7.
What is composition function?"Composition function is defined as where two function combined together to create a new function. It is denoted by 'o'."
According to the question,
Given,
f(x) = x² + x
g(x) = 3x + 1
Substitute the value x=-2 in function f(x) we get,
f(-2) = (-2)² +(-2)
= 4 -2
= 2 ______(1)
Again substitute the value of x = f(-2) in g(x) to get composition function,
g(f(-2)) = 3f(-2) +1
Substitute the value f(-2) from (1) we have,
g(f(-2)) = 3(2) + 1
⇒ g(f(-2)) = 7
Hence, value of g(f(-2)) is equals to 7.

Answer:
0.6 deg/s²
Step-by-step explanation:
Acceleration is the time rate of change of velocity, it is the ratio of velocity to time. The formula for acceleration is given by:
Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time
Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²
1 min = 60 seconds
1 min² = 60² s² = 3600 s²
[tex]2160\ deg/min^2=\frac{2160\ deg}{1\ min^2*3600\ \frac{s^2}{min^2} }=0.6\ deg/s^2\\ \\2160\ deg/min^2=0.6\ deg/s^2[/tex]

Answer:
6x−5=(2)(3)x+4
Step 1: Simplify both sides of the equation.
6x−5=(2)(3)x+4
6x+−5=6x+4
6x−5=6x+4
Step 2: Subtract 6x from both sides.
6x−5−6x=6x+4−6x
−5=4
Step 3: Add 5 to both sides.

Is it true that ƒ −(g − h) = (ƒ − g) − h? Explain why you believe the equation is true or provide a counterexample to show that it is not.
Answer:
The expression is false
Step-by-step explanation:
Given
[tex]f - (g - h) = (f - g) - h[/tex]
Required
True or False
To determine if the expression is true or false, we need to simplify both sides of the equation
[tex]f - (g - h) = (f - g) - h[/tex]
Start by opening the bracket on the right hand side
[tex]f - (g - h) = f - g - h[/tex]
Then open the bracket on the left
[tex]f - g + h = f - g - h[/tex]
Subtract f - g from both sides
[tex]f - g - (f - g) + h = f - g - (f - g) + h[/tex]
[tex]f - g - f + g + h = f - g - f + g - h[/tex]
[tex]f - f - g + g + h = f - f - g + g - h[/tex]
[tex]h \neq -h[/tex]
Hence;
The statement is false
To further check;
Assume f = 5; g = 4 and h = 3
[tex]f - (g - h) = (f - g) - h[/tex] becomes
[tex]5 - (4 - 3) = (5 - 4) - 3[/tex]
[tex]5 - 4 + 3 = 5 - 4 - 3[/tex]

Domain: [tex](-\infty,\infty)[/tex]
Range: [tex](1,\infty)[/tex]
Step-by-step explanation:
The domain of a function is the span of x-values it covers.
The range of a function is the span of y-values it covers.
From the graph, we can see that the domain stretches infinitely in both directions. Therefore, the domain is all real numbers.
In interval notation, this is:
[tex](-\infty,\infty)[/tex]
For the range, note that horizontal line at y=1.
The dotted line tells us that there is a horizontal asymptote there. In other words, y would never reach exactly 1.
Thus, our range would be all values greater than 1 (to positive infinity).
In interval notation, this is:
[tex](1,\infty)[/tex]
And we're done :)
Name two lines in the diagram.
Answer: Line BC and Line DE
Step-by-step explanation:
In geometry terms, we can say that for any set of two points, we always can find a line that passes through them.
For example, in the image, we can see two lines (but actually we could make more with those points)
We can see a line that connects points B and C, and we can call that line as:
Line BC
We also can see a line that connects the points D and E, we can call this line as:
Line DE
So the two lines are: Line BC and Line DE

Find the distance between the points (2,-9) and (-1,4)
Answer:
The answer is
[tex]\sqrt{178} \: \: or \: \: 13.34 \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(2,-9) and (-1,4)
The distance between them is
[tex]d = \sqrt{ ({2 + 1})^{2} + ({ - 9 - 4})^{2} } \\ = \sqrt{ {3}^{2} + ({ - 13})^{2} } \\ = \sqrt{9 + 169} \\ [/tex]We have the final answer as
[tex] \sqrt{178} \: \: or \: \: 13.34 \: \: units[/tex]Hope this helps you
Answer:
[tex]\sqrt{178}[/tex] ≈ 13.3
Step-by-step explanation:
Calculate the distance using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, - 9) and (x₂, y₂ ) = (- 1, 4)
d = [tex]\sqrt{(-1-2)^2+(4+9)^2}[/tex]
= [tex]\sqrt{(-3)^2+13^2}[/tex]
= [tex]\sqrt{9+169}[/tex]
= [tex]\sqrt{178}[/tex] ≈ 13.3 ( to 1 dec. place )
Clare had $110 in her saving. She wanted to buy an MP3 player for $ 118 what is the difference between how much money Clare had and how much she needed
Answer:
$8
Step-by-step explanation:
We want to find the difference between the money Clare has and the money she needs.
Difference means subtract, so we should subtract the amount of money she has from the amount she needs.
money needed - money she has
She has $110 and she needs $118 to purchase the MP3 player.
$118 - $110
Subtract 110 from 118.
$8
The difference between the money Clare has and the money she needs is 8 dollars.
Given g(x)=3x2+3 find x if g(x)=78 Help me please
Answer:
The answer is 5
Step-by-step explanation:
Given g(x)=3x2+3 find x if g(x)=78 = 5
Hope this helped you :)
Answer:
x = ± 5
Step-by-step explanation:
Given
g(x) = 3x² + 3 and g(x) = 78 , then equate the right sides, that is
3x² + 3 = 78 ( subtract 3 from both sides )
3x² = 75 ( divide both sides by 3 )
x² = 25 ( take the square root of both sides )
x = ± [tex]\sqrt{25}[/tex] = ± 5
That is x = - 5 or x = 5
