Answer: y= -8
Step-by-step explanation:
5( 3y+4) = 6( 2y-2/3)15y+20=12y-415y-12y=-4-203y=-24y=-24/3y= -8can you find the slope -intercept equation of each line code ?
Answer:
You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.
Step-by-step explanation:
The Slope-Intercept Form Formula: y=mx+b
The m represents the slope while the b represents the y-intercept
You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.
Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.
What are the zeros of the polynomial function F(x) = x2 -5x-6?
O A. x= -1 and x = 6
O B. x= -6 and x = 1
O C. x = 2 and x = 3
O D. x= -3 and x = -2
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
Answer
x = 2 and x = 3

Step-by-step explanation:
To find equivalent inequalities, we are looking to isolate x on the left side.
a) x < 4 ✅
b) x -1 < 3 add 1 to both sides x -1 +1 < 3 +1 result x < 4 ✅
c) x + 1 < 4 subtract 1 from both sides x + 1 -1 < 4 -1 result x < 3 ❌
d) x - 2 < 2 add 2 to both sides x - 2 +2 < 2+2 result x < 4 ✅

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

B: {20, 23, 25, 21, 24, 22, 60}
C. 20, 21, 20, 22, 20, 24, 99}
Which answer shows the standard deviations of the data sets in order from greatest to least?
- C, B, A
-В, А, С
- A, B, C
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.

[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,

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.
Thus, 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.

A deposit of $2,960 is placed into a scholarship fund at the beginning of every six months for 13 years. The fund earns 7% annual interest, compounded biannually, and paid at the end of the six months. How much is in the account right after the last deposit? Select the correct answer below:
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.

8 - 2(4v + 6) = - 4 - 8v
Answer:
See below ~
Step-by-step explanation:
8 - 2(4v + 6) = -4 - 8v8 - 8v - 12 = -4 - 8v-8v - 4 = -4 - 8vOn placing any value for v, they will be equalIt has infinitely many solutionsAnswer:
Hello! The solution to this linear equation is 0 = 0. To find this solution:
Distribute -
8 - 2(4v+6) = -4 - 8v
8 - 8v - 12 = 14 - 8v
Subtract the numbers -
8 - 8v - 12 = -4 - 8v
-4 - 8v = -4 - 8v
Rearrange terms -
-4 - 8v = -4 - 8v
-8v - 4 = -4 - 8v
Rearrange terms -
-8v - 4 = -4 - 8v
-8v - 4 = -8v - 4
Add 4 to both sides -
-84v - 4 = -8v - 4
-8v - 4 + 4 = -8v - 4 + 4
Simplify -
-8v - 4 + 4 = -8v - 4 + 4
-8v = -8v - 4 + 4
-8v = -8v
Add 8v to both sides -
-8v = -8v
-8v + 8v = -8v + 8v
Combine like terms and simplify -
-8v + 8v = -8v + 8v
0 = -8v + 8v
0 = 0
The solution is 0 = 0. This is an identity: it is true for all values.

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

How many solutions are there to the equation below?
x = -5
O A. 2
O B. 1
O c. o
D. 25
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.
