Solve x2-6x=-5 by completing the square. show ALL work
Answers
Have a nice day, be safe and healthy :)
Hope this helped
formula:
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
Then let's do the square root of equality (square rooting both sides) :
x-3 = 2
Finally lets add 3 to both sides
x = 5
THE ANSWER IS x=5
Have a nice day, be safe + healthy - Hope this helped

If you have a question something like this: "Determine which integer makes the inequality 6(n − 5) < 3(n + 4) true."
The answer would most likely be the last answer choice.
This is because when teachers create the question they put it as the last one to make you work out all of the firsts ones first so you can do more work which means more practice.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

The solution of the given inequality is found to lying in the interval of be: x ∈ [1, 3].
Explain about the inequality?Equations featuring greater-than or less-than letters in place of equal signs are known as inequalities. An inequality can have more than one solution, unlike equations, which only have one.
This is due to the fact that they do not have to be equal; rather, they might have something that is less or greater than. Last but not least, two-variable inequality graphs have a line with half of the graph that is shaded, depending on whether the inequality was less-than or greater-than.An open sentence's result is either correct or incorrect when a number is used in place of the variable. The number is a solutions to the equation as well as inequality if the statement is true.The given inequality is:

Age month, months, months, months, months
Temperature , , ,

Answer:

Step-by-step explanation:

The number of ways of combining different growth factors to form a level is 80.
What is Permutation?The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.
A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.
nPr = (n!) / (n-r)!
What is a Combination?The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).
A combination is a selection of r items from a collection of n items with no replacements and no regard for order.
nCr = (n!)/{(r!)((n-r)!)}
How do we solve the given question?We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting: Low, Medium, High, Very high.
Age: 1 month, 2 months, 3 months, 4 months, 5 months.
Temperature: 20°, 22°, 24°, 26°.
We are asked to find the number of ways in which she can combine different levels to form one level.
We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.
Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).
Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).
Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).
∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80
∴ The number of ways of combining different growth factors to form a level is 80.

When you’re multiplying exponents with the same bases, add powers together, so...
4^5 × 4^9 = 4^14
= 4^14/4^7
When you're dividing exponents with the same bases, subtract powers from each other, so...
4^14 - 4^7 = 4^7

Step-by-step explanation:
Set up cross-multiplication.
If Michelle reads 1/3 book in 2 1/2 hours, she reads X in 1 hour.
1/3 2 1/2
x 1
1/3 = 2 1/2 x
divide by 2 1/2
1/3 divided by 2 1/2 = convert 2 and a half to 5/2
1/3 divided by 5/2 - keep, change, flip. (your teacher should have covered a method like that)
1/3 times 2/5 is 2/15.
For question 2, lets do the same thing.
3/5 times 2/3 equals x times 1
3/5 times 1 is 3/5
2/3 times x is 2/3x
(this looks better on paper)
3/5=2/3x
divide by 2/3
