Hello,

I’m confused on this
Answer:
x = 25
Step-by-step explanation:
The mistake here is the squaring. When you square one side, you have to do the same on the other side:
[tex]\sqrt{3x+6}[/tex] = 9
[tex](\sqrt{3x+6}) ^{2}[/tex] = [tex]9^{2}[/tex]

The mistake is in Step 1. The solver should have also squared [tex]9[/tex] when squaring the other side of the equation.
Correctly solving[tex]\begin{aligned}\sqrt{3x+6}&=9\\(\sqrt{3x+6})^2&=9^2\\3x+6&=81\\3x+6-6&=81-6\\3x&=75\\\frac{3x}{3}&=\frac{75}{3}\\x&=25\end{aligned}[/tex]

What is a polynomial function?A polynomial function is a relation where a dependent variable is equal to a polynomial expression.
A polynomial expression is an expression including numbers and variables, where variables are raised to non-negative powers.
The general form of a polynomial expression is:
a₀ + a₁x + a₂x² + a₃x³ + ... + anxⁿ.
The highest power to a variable is the degree of the polynomial expression. When degree = 2, the function is a quadratic function.
When degree = 1, the function is a linear function.
How do we solve the given question?
The quadratic function is given to us:f(x) = 2x^2 + x + 4.
We need to determine the linear equation g(x).
Since it's a linear equation we use the two-point method to determine the equation.
What is the two-point?y-y₁ = ((y₂-y₁)/(x₂-x₁))*(x-x₁)
We take the points g(-2) =1, g(-1) = 3
g(x) - g(1) = ((g(-2)-g(-1))/(-2+1))*(x-1)or,
g(x) - 1 = ((-2-(-1))/(-2+1))*(x-1)or, g(x) - 1 = -1(-x+1)or,
g(x) = x - 1 + 1 = x
∴ g(x) = x , is the linear function g(x)
We are asked to find the solution to the system of equations f(x) and g(x).To find the solution we need to check what is the common solution to both f(x) and g(x).
For that, we equate f(x) and g(x).2x^2 + x + 4 = x or, 2x² - x +x- 4 = 0or, 2x^2 - 4 = 02(x^2-2)=0x^2-2=0[tex]x^2-\sqrt{2}=0[/tex][tex](x-\sqrt{2}) (x+\sqrt{2})=0[/tex][tex](x-\sqrt{2})=0 \\x=\sqrt{2} or x=-\sqrt{2}[/tex]g(-1) = 3(from the table)[tex]g(\sqrt{2})=\sqrt{2} \ and \ g(\sqrt{-2}) =-\sqrt{2}[/tex][tex]f(\sqrt{2}) = 2(\sqrt{2} )^2 + (\sqrt{2} ) + 3\\=2(2)+\sqrt{2} +3\\=7+\sqrt{2}[/tex][tex]g(-\sqrt{2} )= 2(\sqrt{-2} )^2 + (\sqrt{-2} ) + 3\\=2(2)+\sqrt{-2} +3\\=7+\sqrt{-2}[/tex]

Answer:

Step-by-step explanation:
The given equation:
[tex]\cos(x)=2\cos^2(x)-1[/tex]
Let [tex]\cos(x)[/tex] be [tex]y[/tex]:
[tex]y=2y^2-1[/tex]
Rewrite as:
[tex]2y^2-y-1=0[/tex]
After solving quadratic equation, the solutions are:
[tex]y=1~~~~y=-\frac{1}{2}[/tex]
Substitute back [tex]\cos(x)[/tex], it follows:
[tex]\cos(x)=1~~~~\cos(x)=-\frac12[/tex]
For the first equation, the solution is [tex]x=0[/tex] and [tex]x=2\pi[/tex].
For the second equation, general solution is:
[tex]x=\frac{2\pi }{3}+2\pi n,\:x=\frac{4\pi }{3}+2\pi n[/tex]
But for the given interval, we must substitute n=0 into the equations so that the values of x must be within interval. Therefore:
[tex]x=\frac{2\pi }{3},\:x=\frac{4\pi }{3}[/tex]
So, the answers are:
[tex]x=0,~x=\frac{2\pi }{3},\:x=\frac{4\pi }{3},~x=2\pi[/tex]
What are the restrictions for y
X=10/5+y
Answer:
[tex]y\ne-5[/tex]
Step-by-step explanation:
So you have the equation:
[tex]x=\frac{10}{5+y}[/tex]. As you may know, you cannot divide by 0, so y has to be restricted in a way that the denominator is never equal to 0. So to find when y makes the denominator 0, simply set the denominator equal to 0, and solve for y. This gives you the equation: 5+y = 0, y=-5. So the y value CANNOT be equal to -5. Because it makes the denominator 0. so [tex]y\ne-5[/tex] would be the restriction.

The figure presents a circle, the arc of a circle (s), in inches, is equal to the product of the central angle (θ), in radians, and the radius (r), in inches. Please notice that a complete circle has a central angle of 360°.
If we know that θ = 52π/180 and r = 6 inches, then the length of the arc CD is:
s = [(360π/180) - (52π/180)] · (6 in)
s ≈ 32.254 in

Which linear inequality is represented by the graph?
y < 3x + 2
y > 3x + 2
y < One-thirdx + 2
y > One-thirdx + 2
Answer:
y < 3x + 2
Step-by-step explanation:
We will be solving this in slope-intercept form, which is a form that gives us the slope and the y-intercept of the graph explicitly:
[tex]y=mx+b[/tex], m is the slope and b is the y-intercept
We are given that everything to the left of the resulting line is shaded, so we know that the inequality sign will be < (less than). That already eliminates the second and fourth options. We also know the y-intercept, or the point where the graph crosses the y-axis and x is 0. because it is given to us (2, which comes from the point (0,2)). To figure out the slope, we can use the formula since we are given two points [(-3, -7) and (0, 2)] the line passes through. The formula, which is mapped out below, tells us that the slope is just the difference in rise (vertical movement) divided by the difference in run (horizontal movement).
[tex]m=\frac{-7-2}{-3-0} =\frac{-9}{-3} =3[/tex]
Now we have all the information we need to find the inequality. The slope is 3, the y-intercept is 2, and the sign is <. The first inequality fits these criteria, meaning the correct linear inequality is y < 3x + 2

0x==3(2)
Of(x) = 5(2)
f(x) = 5(5)
f(x) = 5(5)-*
Step-by-step explanation:
To reflect a function about the vertical axis, just negate the variable.
For example, if we want to reflect this function
[tex] y = log(x) [/tex]
about the y axis or vertical axis, we just make the x negative
[tex]y = log( - x) [/tex]
Another example,
[tex]y = |x| [/tex]
To reflect about y axis or vertical axis,
[tex]y = | - x| [/tex]
So here l,the answer with negative variables are function that are reflected about the y axis.
The options are the first and the fifth option.

Which function is graphed below?Here we can see that we have a rational function of the form:
[tex]f(x) = \frac{q(x)}{p(x)}[/tex]
Now we notice two things, as x increases, we have a horizontal asymptote that tends to zero.
Then q(x) is a constant, let's say:
q(x) = k
We also can see that we have a vertical asymptote at x = -2, then:
p(x) = (x + 2)
So the rational function is:
[tex]f(x) = \frac{K}{x + 2}[/tex]
Now, notice that when x = 0, the curve intercepts the y-axis at y = 3, then if we evaluate the function in x = 0 we must get:

In this case using the elimination method is actually easier, but the question asks you to use substitution method so....
2x+y= -10
3x-y=0
1st equation: It is better to isolate 2x on both sides because the y is going to be positive no matter what, 2x+y=-10 => y=-2x-10
If you isolated 3x for the 2nd equation, the y will be negative, and you have to divide the whole equation by -1 to make it positive
Now we got y=-2x-10, lets substitute it in the 2nd equation and solve for x:
3x-(-2x-10) = 0
5x+10=0
5x=-10
x=-2
Now lets solve for y:

Write the equation of an ellipse with center (-2,-3), vertical major axis of length 14, and minor axis of
length 8.
Step-by-step explanation:
Since we have a vertical major axis, our ellipse is vertical.
The equation of a vertical ellipse is
[tex] \frac{(y - k) {}^{2} }{ {a}^{2} } + \frac{(x - h) {}^{2} }{ {b}^{2} } = 1[/tex]
where
(h,k) is the center
a is the semi major axis,
b is the semi minor axis
First, let plug in our center
[tex] \frac{(y + 3) {}^{2} }{ {a}^{2} } + \frac{(x + 2) {}^{2} }{ {b}^{2} } = 1[/tex]
Semi means half, so
a is half of 14 which is 7
B is half of 8, which is 4.
[tex] \frac{(y + 3) {}^{2} }{49} + \frac{(x + 2) {}^{2} }{16} = 1[/tex]
