Answer:
c=2
Step-by-step explanation:
(ax+2)(x+b) = ax^2+2x+abx+2b = ax^2+(2+ab)x+2b
Given, ax^2+(2+ab)x+2b = 3x^2+5x+c
a=3
2+ab=5 => 2+3b=5 => 3b=5-2=3 => b=1
2b=c => c=2*1 = 2
So, c=2

Because of a heavy spring runoff, the shoreline of a lake increased from 10.0 miles to 13.8 miles. What was the percent of increase
in the shoreline?
Answer:
The percent of increase in the shoreline was 38%.
Step-by-step explanation:
Given that the shoreline increased from 10 miles to 13.8 miles because of the spring runoff, to determine the percentage by which the shoreline increased, the following calculation must be performed:
10 = 100
13.8 = X
((13.8 x 100) / 10) = X
(1,380 / 10) = X
138 = X
Thus, since 138 - 100 is equal to 38, the percentage by which the shoreline increased was 38%.

Which is the same function as -3x + 7 = y?
A) f(x) = -3x + 7
B) f(-3x) = 7
C) f(7) = -3x
D) f(x) = -3 + 7
The solution is: A) f(x) = -3x + 7 is the same function as -3x + 7 = y.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
given that,
the function is: -3x + 7 = y
now, we have to find the same function as -3x + 7 = y.
now, let, the function is represented by f(x)
so, we have,
y = f(x)
so, we get,
f(x) = y = -3x + 7
we get,
f(x) = -3x + 7
so, f(x) = -3x + 7 is the same function as -3x + 7 = y.
Hence, A) f(x) = -3x + 7 is the same function as -3x + 7 = y.

Compare the two graphs and explain the transformation that was applied to f(x) in order to look exactly like the graph of g(x). How did the transformation affect the domain and range of the function?
You can use tables, graphs, or equations to justify your answer.
The two graphs are represented below.
Answer and Step-by-step explanation: One graph can "transform" into another through changes in the function.
There are 3 ways to change a function:
Shifting: it adds or subtracts a constant to one of the coordinates, thus changing the graph's location. When the y-coordinate is added or subtract and the x-coordinate is unchanged, there is a vertical shift. If it is the x-coordinate which changes and y-coordinate is kept the same, the shift is a horizontal shift;Scaling: it multiplies or divides one of the coordinates by a constant, thus changing position and appearance of the graph. If the y-coordinate is multiplied or divided by a constant but x-coordinate is the same, it is a vertical scaling. If the x-coordinate is changed by a constant and y-coordinate is not, it is a horizontal scaling;Reflecting: it's a special case of scaling, where you can multiply a coordinate per its opposite one;Now, the points for f(x) are:
(-5,0) (0,6) (5,-4) (8,0)
And the points for g(x) are:
(-5,-3) (0,-9) (5,1) (8,-3)
Comparing points:
(-5,0) → (-5,-3)
(0,6) → (0,-9)
(5,-4) → (5,1)
(8,0) → (8,-3)
It can be noted that x-coordinate is kept the same; only y-coordinate is changing so we have a vertical change. Observing the points:
(-5,0-3) → (-5,-3)
(0,6-15) → (0,-9)
(5,-4+5) → (5,1)
(8,0-3) → (8,-3)
Then, the vertical change is a Vertical Shift.
Another observation is that y-coordinate of f(x) is the opposite of g(x). for example: At the second point, y-coordinate of f(x) is 6, while of g(x) is -9. So, this transformation is also a Reflection.
Range of a function is all the values y can assume after substituting the x-values.
Domain of a function is all the values x can assume.
Reflection doesn't change range nor domain of a function. However, vertical or horizontal translations do.
Any vertical translation will change the range of a function and keep domain intact.
Then, for f(x) and g(x):
graph translation domain range
f(x) none [-5,8] [-4,6]
g(x) vertical shift [-5,8] [-9,1]
In conclusion, this transformation (or translation) will affect the range of g(x)

6x + 9 = -12. What is the value of x?
(Six x plus nine, equals negative twelve)
Answer:
The answer is x=-7/2
Step-by-step explanation:
hope this helps
6x + 9 = -12
6x+9-9=-12-9
6x=-21
To find the x divide both side by 6.
6x/6=-21/6
x= -7/2
the answer to this question is = (- 7/2)

Answer:
After finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]
Step-by-step explanation:
We need to find like terms and simplify the expression [tex]4- 2x + x^2 + 5x + 12 + 2x^2[/tex]
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:
[tex]4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16[/tex]
So, after finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]
Note: In the question given we have - and + sign with the term 5x i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:
[tex]4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16[/tex]
So, the answer will be: [tex]\mathbf{3x^2-7x+16}[/tex]

Step-by-step explanation:
A ball is launched upward at 14 m/s from a platform 30 m high.Find the maximum height the ball will reach and how long it will take.
Answer:
The ball will reach a maximum height of 39.993 meters after 1.428 seconds.
Step-by-step explanation:
Let suppose that no non-conservative forces acts on the ball during its motion, then we can determine the maximum height reached by the Principle of Energy Conservation, which states that:
[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (1)
Where:
[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.
[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.
By definition of translational kinetic energy and gravitational potential energy we expand and simplify the expression above:
[tex]\frac{1}{2}\cdot m\cdot v_{2}^{2}+m\cdot g\cdot y_{2}= \frac{1}{2}\cdot m\cdot v_{1}^{2}+m\cdot g\cdot y_{1}[/tex] (2)
Where:
[tex]m[/tex] - Mass of the ball, measured in kilograms.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]v_{1}[/tex], [tex]v_{2}[/tex] - Initial and final speed of the ball, measured in meters per second.
[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the ball, measured in meters.
The final height of the ball is determined by the following formula:
[tex]v_{2}^{2}+2\cdot g\cdot y_{2} = v_{1}^{2}+2\cdot g\cdot y_{1}[/tex]
[tex]v_{1}^{2}-v_{2}^{2}+2\cdot g \cdot y_{1}=2\cdot g\cdot y_{2}[/tex]
[tex]y_{2} = y_{1}+\frac{v_{1}^{2}-v_{2}^{2}}{2\cdot g}[/tex] (3)
If we know that [tex]y_{1} = 30\,m[/tex], [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], the maximum height that the ball will reach is:
[tex]y_{2} = 30\,m + \frac{\left(14\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]y_{2} = 39.993\,m[/tex]
The ball will reach a maximum height of 39.993 meters.
Given the absence of non-conservative forces, the ball exhibits a free fall. The time needed for the ball to reach its maximum height is computed from the following kinematic formula:
[tex]t = \frac{v_{2}-v_{1}}{-g}[/tex] (4)
If we know that [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then:
[tex]t = \frac{0\,\frac{m}{s}-14\,\frac{m}{s} }{-9.807\,\frac{m}{s^{2}} }[/tex]
[tex]t = 1.428\,s[/tex]
The ball will take 1.428 seconds to reach its maximum height.
