The solution to the equation is x = 2 , x = 1/2
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
( 2x - 4 ) ( 2x - 1 ) = 0
So , the two values of x are
when ( 2x - 4 ) = 0
Adding 4 on both sides , we get
2x = 4
Divide by 2 on both sides , we get
x = 2
And , when ( 2x - 1 ) = 0
Adding 1 on both sides , we get
2x = 1
Divide by 2 on both sides , we get
x = 1/2
Hence , the solution is x = 2 , 1/2

O B. x= -6 and x = 1
O C. x = 2 and x = 3
O D. x= -3 and x = -2
Answers
Answer:
C
Step-by-step explanation:
Remark
The zeros are found either by using the quadratic equation or by factoring and equating the factors to 0. I think factoring is the best and simplest way.
Solution
x^2 - 5x + 6 factors into
(x - 3)(x - 2)
-3 and - 2 must multiply to 6 (they do) -3 * -2 = 6
-3 and -2 must also add to - 5. They do. -3 - 2 = - 5
So the factors are correct.
x - 3 = 0
x - 3 + 3 = 0 + 3
x = 3
x-2 = 0
x -2 + 2 = 0 + 2
x = 2

There are two different questions here. One where you get to make up an exponential function and write a table of values. The other is a statistics problem in which you compare 5-number summaries.
__
Exponential FunctionFor the function f(x) = a·b^x, the value of f(0) is 'a'. The given table shows a=96. The only requirement for choosing 'b' is that it not be 1. We can choose b=1/2, and our table will be ...
y = 96·(1/2)^x

Answers
The correct order which shows the standard deviations of the data sets A,B and C in order from greatest to least is C, B, A.
How to find the standard deviation of a data set?Suppose that
[tex]x_i; \: \: i = 1,2, ... ,n[/tex] are n data values for the given data set.
Then we have: Variance as,
[tex]\sigma^2 = \dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}[/tex]
As standard deviation is the positive root of variance, thus,
[tex]\sigma = \sqrt {\dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}}[/tex]
If its sample, we divide by n-1 instead of n
Use data sets A, B, and C to answer the question that follows.
A {25, 24, 25, 22, 21, 23, 1}B: {20, 23, 25, 21, 24, 22, 60}C. {20, 21, 20, 22, 20, 24, 99}The mean of the set A is,
[tex]\overline{x}_A=\dfrac{25+24+ 25+ 22+ 21+23+ 1}{7}=20.143[/tex]
Similarly, the mean of set B and C is,
[tex]\overline{x}_B=\dfrac{20+ 23+ 25+ 21+ 24+ 22+ 60}{7}=27.857\\\overline{x}_C=\dfrac{20+21+ 20+ 22+ 20+ 24+ 99}{7}=32.286[/tex]
The standard deviation of the set A is,
[tex]\sigma_A = \sqrt {\dfrac{(25-20.143)^2+(24-20.143)^2......+(1-20.143)^2}{7}}\\\sigma_A = 7.936[/tex]
Similarly, the standard deviation of set B and C is,
[tex]\sigma_B = \sqrt {\dfrac{(20-27.857)^2+(23-27.857)^2......+(60-27.857)^2}{7}}= 13.217\\\sigma_C = \sqrt {\dfrac{(20-32.286)^2+(21-32.286)^2......+(99-32.286)^2}{7}}= 27.27[/tex]
The value of standard deviation of set C is the highest while set A is lowest.

2(30)+2(22)2(30+22)2(52)104inAnswer:
104 inches
Step-by-step explanation:
A kite has two pairs of consecutive, congruent sides.
Therefore, BC = AB and AD = DC
We can use this to determine the values of x and y, and then the perimeter of the kite.
If BC = AB
⇒ 5x = 3x + 12
Subtract 3x from both sides:
⇒ 2x = 12
Divide both sides by 2
⇒ x = 6
If AD = DC
⇒ 11y - 22 = 7y - 6
Subtract 7y from both sides:
⇒ 4y - 22 = -6
Add 22 to both sides:
⇒ 4y = 16
Divide both sides by 4:
⇒ y = 4
As BC = AB and AD = DC
⇒ perimeter = 2 (BC + AD)
= 2 (5x + 11y - 22)
Substituting found values of x and y:
⇒ perimeter = 2 (5(6) + 11(4) - 22)
= 2 (30 + 44 - 22)
= 2 (52)
= 104 inches

A. The quesadillas cost $3.11 each, and the tacos cost $1.69 each.
B. The quesadillas cost $1.57 each, and the tacos cost $3.45 each.
C. The quesadillas cost $3.39 each, and the tacos cost $1.69 each.
D. The quesadillas cost $3.39 each, and the tacos cost $1.57 each.
Answers
C
Explanation:
You could solve this in the elimination way that I have been done in here.
I use Jason as an example that he paid $11.84 for 5t ( tacos ) + 1q ( quesadilla )
Therefore we could do the elimination if the taco cost 3.45 x 5 = 17.25, would be over the cost.
-> Cross B answer
Then we take 1.57 x 5 = 7.85. 11.84 - 7.85 = 3.99, which it is not 3.39 => Cross D answer.
Therefore the cost of tacos need to be 1.69 because there have been a repetition in both A& C
1.69 x 5 = 8.45. $11.84 - 8.45 = $3.39 for quesadillas.
Which it proves for the answer is C

We will see that the equation has only one solution, so the correct option is B.
How many solutions an equation has?
For an equation of the form:
p(x) = C
Where p(x) is an expression that depends on x, and C is a constant.
The solutions are all the values of x that make the equality true.
For our case, we have:
x = -5
Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:
-5 = -5
So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

Answers
Answer:
where are the awnsers??
The value of the initial deposit is $2,960, so a1=2960. A total of 26 six-month deposits are made in the 13 years, so n=26. To find r, divide the annual interest rate by 2 to find the biannual interest rate and add 1 to represent the new biannual deposit.
r=1+0.072=1.035
Substitute a1=2960, n=26, and r=1.035 into the formula for the sum of the first n terms of a geometric series and simplify to find the value of the annuity.
S26=2960(1−1.03526)1−1.035≈122286.78
Therefore, the account has $122,286.78 after the last deposit is made.
