Answer:
x=5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Consider 8x2 - 48x = -104.
Write the equation so that a = 1: x2 + __ = __
Complete the square:
x² - 6x + __ -13 + __ = __
Factor the trinomial and simplify:
(x + __ )² = __
Use the square root property of equality to solve (x-3)² = -4.
The solutions are ______.
Answer:
[tex]3+ 2\mathbf{i}[/tex]
[tex]3- 2\mathbf{i}[/tex]
Step-by-step explanation:
Quadratic Equation Solving
We have the equation:
[tex]8x^2-48x=-104[/tex]
Divide by 8:
[tex]x^2-6x=-13[/tex]
Now complete the squares so the left side is a perfect square of a binomial:
[tex]x^2-6x+9=-13+9=-4[/tex]
Factoring the perfect square:
[tex](x-3)^2=-4[/tex]
Taking the square root:
[tex]x-3=\sqrt{-4}[/tex]
The square root of a negative number is an imaginary number:
[tex]x-3=\pm 2\mathbf{i}[/tex]
Solving for x:
[tex]x=3\pm 2\mathbf{i}[/tex]
The solutions are:
[tex]3+ 2\mathbf{i}[/tex]
[tex]3- 2\mathbf{i}[/tex]

A T-shirt vendor
sells yellow shirts and
blue Shirts at a ratio of
1:4. What percent of the
Shirts are yellow?
The percentage of the T-shirt that are yellow will be 20%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A T-shirt vendor sells yellow shirts and blue Shirts at a ratio of 1: 4.
The ratio of the yellow T-shirt is given as,
Yellow ratio = 1 / (4 + 1)
Yellow ratio = 1 / 5
Then the percentage of the T-shirt that are yellow will be given as,
P = [1/5] x 100
P = 0.20 x 100
P = 20%
The percentage of the T-shirt that are yellow will be 20%.

Which are correct representations of the inequality 6x2 3 + 4(2x - 1)? Select three options.
Answer:
Option A, B, and C.
Step-by-step explanation:
Given, 6x ≥ 3 + 4(2x - 1),
Solve to find the correct representations given in the options.
6x ≥ 3 + 4(2x - 1)
Apply distributive property
6x ≥ 3 + 8x - 4 (option B is correct) ✅
Add like terms
6x ≥ -1 + 8x
Add 1 to both sides
6x + 1 ≥ 8x
Subtract 6x from each side
1 ≥ 8x - 6x
1 ≥ 2x (option A is correct) ✅
Divide both sides by 2
1/2 ≥ 2x/2
½ ≥ x
½ ≥ x means all possible values of x are less than 0.5. representing this inequality on a graph, we would have the directed line starting at 0.5 moving towards our left.
This make option C correct.✅

What is the radius and diameter of the following circle?
18 cm
Radius =
cm
Diameter =
cm
Report a probl
st
Answer:
radius=9cm
diameter=18cm
Step-by-step explanation:
Answer:
Radius = 9cm
Diameter = 18cm
Step-by-step explanation:
Remember that the diameter of a circle is the distance between two opposite sides (crossing the middle), and the radius is half of that - the distance from the middle to the outside.
the image shows that the diameter is 18cm, so we know that the radius is 18cm/2, which equals 9cm.
1/2 |2x-3|+5=13
Solve for x
Answer:
x=19/2
x=- 13/2
Step-by-step explanation:
multiply both sides by 2 |2x -3|+10=26
move constant (10 to the right and change sign |2x-3|=26-10
subtract the numbers |2x-3|=16
use absolute value (rewrite the absolute value 2x-3=16
equation as two separate equations one (+) and (-) 2x-3= -16
2x-3=16 move constant to the right
2x=16+3 add the numbers
2x=19 divide both sides by 2
x=19/2
same steps with with second one
2x-2= -16
2x= -16 +3 move constant to the right change sign and add
2x= -13 divide both sides by two
x= -13/2
The | | are not ( ) . They have different meaning , absolute value brackets. ok :)

Line is passing through the points (1, 1) & (0, 4)
Slope of line = (4-1)/(0-1) = 3/(-1) = - 3
Equation of line
y = mx + b
Here m = - 3, b = 4

The first 5 terms of some sequences are given. State a rule that each sequence could follow.

5, 7, 9, 11, 13
50, 25, 0, -25, -50
1/3, 1, 3, 9, 27
The first , second and third sequence is arithmetic and the fourth sequence is geometric.
A sequence is a series of numbers such that each number follows a very specific rule or explicit function which determines its value. There are numerous types of sequence and series . But for this particular question we will need to know :
Arithmetic sequence : Number in an arithmetic sequence or AP are at equal distance from each other if plotted on a number line. The difference between any two consecutive numbers is the same and it is called the common difference.Geometric sequence : a sequence of numbers is said to be in a GP such that the ratio of each number to the preceding and the succeeding numbers is same.Let us now take each series of numbers and find the type of sequence it is:
sequence 1: 2, 4, 6, 8, 10
Common difference = 10-8 = 6-4 =2
So the sequence is arithmetic.
sequence 2: 5, 7, 9, 11, 13
Common difference = 13-11 = 7-5 =2
So the sequence is arithmetic.
sequence 3: 50, 25, 0, -25, -50
Common difference = 50-25 = - 25 - ( - 50) = 25
So the sequence is arithmetic.
sequence 2: 5, 7, 9, 11, 13
Common difference = 13-11 = 7 - 5 =2
So the sequence is arithmetic.
sequence 2: 1/3, 1, 3, 9, 27
Common ratio = 3 ÷ 1 = 27 ÷ 9 = 3
So the sequence is geometric.

What is the value of x in the equation
5(2x-7)=15x-10?
Answer:
x = -5
Step-by-step explanation:
First distribute the 5 on the right side of the equation.
10x - 35 = 15x - 10
Then subtract 10x on each side
-35 = 5x - 10
Then add 10 on each side
-25 = 5x
Divide 5 on each side to get x
-25 / 5 = -5
I hope this helps! :)
Answer:

y= 8-2x tell the answer with explanation
The equation has infinite solutions which lie on the graph of this equation.
We have the following equation -
y = 8 - 2x
We have to solve for the possible values of x and y for which the equation is satisfied.
Define rearrangement of a mathematical equation.The rearrangement of a mathematical equation is process of expressing a variable in a equation in terms of other variables, constants etc.
According to the question, we have the following equation -
y = 8 - 2x
Rearranging the equation -
y = - 2x + 8
Now, plot the equation on graph - (Graph is attached at the end)
All the coordinates on this line satisfy the equation → y = 8 - 2x.
Hence, the equation has infinite solutions which lie on the graph of this equation.
