Answer:
The function has a maximum of 2 at [tex]x=1[/tex]
Step-by-step explanation:
The graph is a vertical parabola. The minimum, or min is when the parabola opens up, the vertex is at the lowest point on the graph. The maximum, or maxis when the parabola opens down, the vertex is the highest point on the graph.
Since it asks for "[tex]x[/tex]", we can tell that it is 1. If you look at the x-axis in the graph at where the point lies, you will find that [tex]x=1[/tex]

how do I add odd number fractions for example 5/9 and 3/5?
Answers
Answer:
if the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find at least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with common denominator. Then add and simplify
Answer:
[tex]\frac{52}{45}[/tex] or [tex]1\frac{7}{45}[/tex]
Step-by-step explanation:
In order to add two fractions with different denominators, you will have to find its least common denominator (LCD):
The LCD of 9 and 5 is 45.
Next, we'll start with 5/9:
Divide 45 by 9, which results in 5. Then, multiply the numerator by 5:[tex]\frac{5}{9} = \frac{5*5}{45} = \frac{25}{45}[/tex]
The same goes with 3/5:
Divide 45 by the denominator, 5, then multiply 5 by the numerator 3:
[tex]\frac{3}{5} = \frac{9*3}{45} = \frac{27}{45}[/tex]
Now, we can finally add 25/45 and 27/45 since they have the same denominator. Doing so results in a sum of 52/45:
[tex]\frac{25}{45} + \frac{27}{45} = \frac{52}{45}[/tex]
If you have to transform 52/45 into a proper fraction (which will result in a mixed fraction), then it will be [tex]1\frac{7}{45}[/tex].

Calculate the % loss
Cost price of an article =$28
Selling price of the article=$21
Answers
The loss in percentage is 25%.
Given that,
Cost price of an article = $28
Selling price of the article = $21
We know that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Now loss can be calculated by subtracting selling price from cost price,
Therefore,
28 - 21 = 7
Hence there are loss of $7 in business,
Now to calculate percentage loss,
Divide loss by cost price then multiply with 100,
Then,
⇒ (7/28)x100
⇒ 25%

Rewrite as an exponential equation.
Answers
Step-by-step explanation:
The first technique we will introduce for solving exponential equations involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, S, and T, where

,
b

,
b
S

if and only if S = T.
In other words, when an exponential equation has the same base on each side, the exponents must be equal. This also applies when the exponents are algebraic expressions. Therefore, we can solve many exponential equations by using the rules of exponents to rewrite each side as a power with the same base. Then we use the fact that exponential functions are one-to-one to set the exponents equal to one another and solve for the unknown.
For example, consider the equation

4
x

. To solve for x, we use the division property of exponents to rewrite the right side so that both sides have the common base 3. Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for x:

Does -a ? = (-a)?? Explain why or why not.
Answers
Explanation:
Always remember that variables have coefficients (x is the same as 1·x or 1x).
Raising a base to either an odd or even exponent has particular rules when it comes to signs:
If you raise -a² = -a² because a has a coefficient of - 1. This implies that -a² = -1a². Now, raising -a³ (odd exponent) still results in -a³ because you're only raising the base, a, to its exponent, and it doesn't include its coefficient of -1. Hence, -a³ = -1a³ = -a³.Also, (-a²) = -a² because once again, you're only raising the base, a, and not its coefficient (even if both are inside the parenthesis).It will be different if the base is raised as follows:
(-a)² = a² because the coefficient, -1, is included within the parenthesis. It is the same as (-1a)² = 1a² or a².(-a)³ = -a³ or -1a³ because it is an odd exponent, and if you raise a negative base to an odd exponent results in a negative value of the base.The key is that the exponent outside the parenthesis will affect both the coefficient and its base, such as (-a)².
