B. 3 + 2/5 2
C. 2 + √24 2
D. 5 + 10 3
The solutions to the given quadratic equation are (3+√5)/2 and (3-√5)/2.
What is the quadratic formula?Quadratic formula is the simplest way to find the roots of a quadratic equation.
The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.
The given quadratic equation is x²-3x+1=0.
By comparing x²-3x+1=0 with ax²+bx+c=0, we get a=1, b=-3 and c=1.
Now, x= [3±√((-3)² - 4×1×1)]/2×1
= [3±√(9-4)]/2
= (3±√5)/2
So, the solutions to the given equation are (3+√5)/2 and (3-√5)/2.
Therefore, the solutions to the equation are (3+√5)/2 and (3-√5)/2.

2 (3x - 5) + 4 = -18
Solve for 20 Points
Answer:
x = -2
Step-by-step explanation:
2(3x - 5) + 4 = -18
Distribute the 2
6x - 10 + 4 = -18
6x - 6 = -18
Add 6 to both sides
6x = -12
Divide both sides by 6
x = -2
Check:
2(3x - 5) + 4 = -18
substitute x = -2 into the original equation
2(3(-2) - 5) + 4 = -18
2(-6 - 5) + 4 = -18
2(-11) + 4 = -18
-22 + 4 = -18
-18 = -18
So x = -2 is true.
Answer:
x=-2
Step-by-step explanation:
2(3x-5)+4=-18
We move all terms to the left:
2(3x-5)+4-(-18)=0
We add all the numbers together, and all the variables
2(3x-5)+22=0
We multiply parentheses
6x-10+22=0
We add all the numbers together, and all the variables
6x+12=0
We move all terms containing x to the left, all other terms to the right
6x=-12
x=-12/6
x=-2

PLS HELP ME 12x - 15 = 6 - 3x
Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)
Answer:
x= 21/15
if you need to reduce it would be x=7/5
Step-by-step explanation:
12x-15 =6-3x
add 3x to both sides
15x- 15 = 6
now add 15 to both sides
15x = 21
lastly divide both sides by 15
x= 21/15
if you need to reduce it would be x=7/5
Answer:
x = 7/5 or 1.4
Step-by-step explanation:
12x - 15 = 6 - 3x Need to move one variable term to the other side to
+3x + 3x isolate it on one side
---------------------------
15x - 15 = 6 need to +15 to isolate the variable term
+15 +15
-----------------------
15/15x = 21/15 (simplify 21/15 = 7/5) need to divide by 15 to isolate x
------------------------
x = 7/5 or 1.4

7) Isidro pays $20 a month for Netflix. He also pays $0.10 for each
show he streams. Last month Isidro had a Netflix bill of $40. Write
and solve an equation to determine how many shows Isidro streamed
last month.
Answer:
200 shows
Step-by-step explanation:
subtract the total ($40) from how much he pays a month ($20) to get the total of how much he paid in shows total ($20)
40-20=20
divide the total bill of shows ($20) by how much it costs per show ($0.10) to get how many shows he has watched (200)
20/0.10=200

Use elimination to solve the system of equations. Enter your answers in the boxes.
3x - 2y = 24
x + 2y = 48
X =
Hy=
v
Answer:
x = 18 , y = 15
Step-by-step explanation:
Given the 2 equations
3x - 2y = 24 → (1)
x + 2y = 48 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 72
4x = 72 ( divide both sides by 4 )
x = 18
Substitute x = 18 into either of the 2 equations and solve for y
Substituting into (2)
18 + 2y = 48 ( subtract 18 from both sides )
2y = 30 ( divide both sides by 2 )
y = 15
Angles a and b are complementary angles symmetry of angle a is 28° more than the measure of angle b find the missing angle measures
Answer:
31 , 59
Step-by-step explanation:
a = b +28
a + b = 90 {Complementary}
b + 28 + b = 90 {Combine like terms}
2b + 28 = 90 {Subtract 28 form both sides}
2b = 90 - 28
2b = 62 {Divide both sides by 2}
b = 62/2
b = 31
a = 31 + 28
a = 59

Which of the rules given below shows the transformation of f?
OA g(x) = f(x) - 4
O B. g(x) = fx-4)
OC.
g(x) = f(x + 4)
OD. g(x) = f(x) + 4
Answer:
A.) g (x) = f (x) - 2
Step-by-step explanation:
The first thing we are going to do in this case is to take into account the following definition.
Translations are transformations that change the position of the graph of a function.
The general shape of the graph of a function is moved up, down, to the right or to the left.
The translations are considered rigid transformations. Now we will see how these are performed.
Vertical translations:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
Using the definition we conclude that:
g (x) = f (x) - 4
Two exponential functions, fand g, are shown in the figure, where g is a transformation of f, g (x) = f (x) - 4 equation shows transformation of f. The correct option is A.
What is exponential function?A mathematical function of the form [tex]f(x) = a^x[/tex], where an is a positive constant and x is the input variable, is an exponential function.
The characteristic curve of exponential functions rises or falls rapidly depending on whether an is greater or less than 1.
To determine the transformation of f which gives g, we need to examine how f has been transformed to obtain g.
Looking at the graph, we can see that g is a vertical shift of f. Specifically, g is obtained by shifting f downward by 2 units. Therefore, we need a rule that subtracts 2 from f (x) to get g (x).
Out of the given options, the only one that matches this description is:
g (x) = f (x) - 4
Option A subtracts 4 from f (x), which is not what we observe in the graph. Option B uses an incorrect format and is also subtracting 4 from f (x).
Option C adds 4 to x, which would result in a horizontal shift, not a vertical shift.
Therefore, the correct answer is A g (x) = f (x) - 2.

h(1)= 9
h(n)=h(n−1)⋅(-3)
Find an explicit formula for h(n).
h(n)= ?
Given:
[tex]h(1)=9[/tex]
[tex]h(n)=h(n-1)\cdot (-3)[/tex]
To find:
The explicit formula for h(n).
Solution:
We have,
[tex]h(n)=h(n-1)\cdot (-3)[/tex] ...(i)
It is the recursive formula of a geometric sequence. It is of the form
[tex]a(n)=a(n-1)\cdot r[/tex] ...(ii)
where r is the common ratio.
On comparing (i) and (ii), we get
[tex]r=-3[/tex]
We have, [tex]h(1)=9[/tex] so the first term of the geometric sequence is [tex]a=9[/tex].
The explicit formula for a geometric sequence is:
[tex]h(n)=ar^{n-1}[/tex]
Substitute a=9 and r=-3 to get the explicit formula for the given sequence.
[tex]h(n)=9(-3)^{n-1}[/tex]
Therefore, the required explicit formula is [tex]h(n)=9(-3)^{n-1}[/tex].
