(1, 2)
(−∞, 0)
Note: Multiple choice question
Answers
Answer:
The intervals where the function is increasing are [tex](-\infty,0)[/tex] and [tex](1,2)[/tex]
Step-by-step explanation:
We are required to find the intervals in which the function is increasing.
From the figure, we see that,
The graph is going up towards the origin to reach the point (0,0).
Then, it is going down in the interval (0,1).
Then, it is again going up to reach the point (2,0).
Finally, it is going downwards towards infinity.
Thus, we see that,
The intervals where the function is increasing are [tex](-\infty,0)[/tex] and [tex](1,2)[/tex]
Answer:(−∞, 0) and(1,2)

[tex] x^{2} -2x-3[/tex] to do this we'll need to find two number whose product is -3 and its sum is -2; those numbers are 1 and -3, so:
[tex] x^{2} -2x-3=(x+1)(x-3)[/tex]
Now we can rewrite our rational function as follows:
[tex]f(x)= \frac{x-3}{(x+1)(x-3)} [/tex]
Notice that we have a common factor (x-3) in both numerator and denominator; therefore we can cancel them:
[tex]f(x)= \frac{1}{x+1} [/tex]
Taking all the above into consideration we realize that x=3 is a removable discontinuity; the correct answer is the first one: there is a hole in x=3 and asymptote at x=-1.

Factorization fails
The factorized form of the algebraic expression 15x²y² - 3x³y + 75x⁴ is 3x²(5y² - xy + 15x²).
What is the factorization of algebraic expressions?Factorization of algebraic expressions is a process to break the expression and show it as a product of two or more smaller expressions by grouping and taking the greatest common factor out of the groups.
How to solve the question?In the question, we have been asked to factor the expression 15x²y² - 3x³y + 75x⁴ completely.
We know that factorization is the process of breaking the expression into smaller expressions.
We first try to find the greatest common factor among the three terms provided in the expression.
First, we will go with the numerical part.
We have 15, -3, and 75.
The greatest common factor for these three is 3.
No, we will go with the variable part.
We have x²y², x³y, and x⁴.
The greatest common factor for these three is x².
Thus, the greatest common factor for the expression is 3x²
.
Taking 3x² common throughout, we get:
3x²(5y² - xy + 15x²), which is the required factored form.

1.4 + 2/5x = 3/15x - 0.8 How do you solve this?
Answers
1.4+2/5x=3/15x-.08
you have to isolate the x
first add .08 to both sides
1.48+2/5=3/15x
i would now find the equivalence fraction of 2/5 with the denominator of 15. To do this you have to multiply 5 by 3 to get 15 so, you multiply the original numerator to get the equivalent one. 2(3)=6
1.48+6/15x=3/15x
now i am going to subtract 6/15x from both sides
1.48= -3/15x
to get rid of the fraction i am going to convert it to a decimal.
-3/15= -.2
1.48= -.2x
now i have to divide both sides by -.2

Does the equation x2 - 4x + y2 = -3 intersect the x-axis?
Answers
x^2 - 4x + 0 = -3
We then want to solve for x. We can do this by factoring.
x^2 - 4x + 3 = 0
By factoring...
(x - 3)(x - 1)
We can set each of these equations = 0 to solve where the function crosses the x-axis.
x - 3 = 0
x = 3
x - 1 = 0
x = 1
So we know at x = 1 and x = 3, the function x^2 - 4x + y^2 = -3 intersects the x-axis.
Answer:
Yes, because the center is on the x-axis.
Step-by-step explanation:
First, write the equation in standard form by completing the square.
x2 - 4x + y2 = -3
x2 - 4x + 4 + y2 = -3 + 4
(x - 2)2 + y2 = 1
The circle is centered at (2, 0) with a radius of 1. Since the circle is centered on the x-axis, it intersects the x-axis two times, at (3, 0) and (1, 0).

Answers
12x + 76(2-x) = 120
Use the Distributive Property:
12x + 76*2 - 76*x = 120
12x + 152 - 76x = 120
Combine like terms:
-64x + 152 = 120
Cancel the 152 by subtracting:
-64x + 152 - 152 = 120 - 152
-64x = -32
Cancel the -64 by dividing:
-64x/-64 = -32/-64
x = 0.5
She runs for 0.5 hours. She would use her jetpack for 2-0.5=1.5 hours.
Eudora ran 0.5 hours and flew 1.5 hours using her jetpack.
Given that, Eudora ran from her home to her secret laboratory at an average speed of 12 km/h.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let x = the time she ran (in hours) and y = the time she flew (in hours).
Remember that distance traveled is simply the rate times the time. So she traveled 12x kilometers by running and 76y kilometers by flying.
The total time is simply the running time plus the flying time: x + y = 2.
The total distance is simply the running distance plus the flying distance: 12x + 76y = 120
If you solve the time equation for x, you get: y = 2 - x.
This allows you to substitute 2 - x into the distance equation for y.
12x + 76(2 - x) = 120
12x + 152 - 76x = 120
152 - 64x = 120
-64x = -32
x = 0.5
Using the result, we can find y.
y = 2 - 0.5 = 1.5
Therefore, Eudora ran 0.5 hours and flew 1.5 hours using her jetpack.

What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
The inequality for the sentence "Fifteen less than a number is at most 6" can be written as:

When csc(theta) sin(theta) is simplified, what is the result?
Answers
Therefore, csc theta * sin theta = 1.
cosec theta = 1/sin theta, sec theta = 1 / cos theta.
Therefore, Equation 2 reduces to,
(1/sin theta) / (1/cos theta) = cos theta/sin theta = 1/tan theta = cot theta.
tan theta + cot theta = tan theta + 1/tan theta. Taking LCM,
= (1 + tan^2 theta)/tan theta
From the identities, 1 + tan^2 theta = sec^2 theta.
Hence, equation 3 reduces to,
sec^2 theta/tan theta = (1/cos^2 theta) / (sin theta/cos theta)
= cos theta / (sin theta * cos^2 theta)
= 1 / (sin theta*cos theta). This cannot be reduced, hence is equal to sec theta*cosec theta.
1-sin^2 theta / 1+sin theta = (1 + sin theta)*(1-sin theta) / (1 + sin theta)
= 1 - sin theta.
