Solve by completing the square (Show all work)
x2 – 10x + 10 = 35

Please help!

Answers

Answer:

x=5+5√2; x=5-5√2

Step-by-step explanation:

To complete the square we need to turn part of the equation into a perfect square trinomial. Remember, in any equation we can do anything we like to the numbers as long as both sides stay equal.

First, let's subtract 10 from both sides.

x^2-10x=25

This does not factor, so we need to turn it into a perfect square trinomial by adding the quantity equal to (b/2)^2. In this case, (b/2)^2 is 25.

x^2−10x+25=25+25

IMPORTANT: You must keep the sides of the equation equal, so we added a 25 to the right side as well to keep the equation true.

From here we can factor, simplify and find our zeroes.

(x-5)(x-5)=50

(x-5)^2=50

x-5=±√50

x=5±√50

√50=5√2

So our final answer is:

x=5+5√2; x=5-5√2

Type the correct answer in the box. Use numerals instead of words. What value of x makes this equation true? -2x + 3 = -15
What does x =

Answers

Answer:x=9

Step-by-step explanation:

-2x+3=-15

Subtract 3 on both sides:

-2x+3-3=-15-3

-2x=-18

Divide -2 on both sides:

-2x/-2=-18/-2

x=9

If the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the equation as follows -

- 2x + 3 = - 15

The given equation is -

- 2x + 3 = - 15

Solving, we get -

- 2x = - 15 - 3

- 2x = - 18

 2x = 18

 x = 9

Therefore, if the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.

Lena will use 7 cups of apples to make 4 batches of applesauc. Which expression shows the number of cups of apples in each batch? Group of answer choices 4/7 3/4 1 3/4 1 1/2

Answers

Answer:  1 3/4 cups of apples in each batch

Step-by-step explanation:

STEP  1

Writing out the equation to represent if 7 cups of  apples make 4 batches   One batch is as a result of how many  cups of apples

LET x be number of cups of apples to make each batch

7 cups of  apples = 4 Batches

        x cups of apples = 1 Batch

STEP 2  Solving by cross multiplication

1 batch x 7 cups of apples = 4 batches  X x cups of apples

x cups of apples=1 batch x 7 cups of apples / 4batches

x   = 7 / 4 =  1 3/4

number of cups of apples to make each batch=  1 3/4

Questions:

Sale price?

Answers

To take 25% off, you want to do 1-.25 which equals .75. That means that you have to pay 75% of the cost after the 25% off discount.

Multiply the cost, 150, by .75 to find the new price after the discount.
150x.75=112.5

The price is now $112.50

.Shaun estimated that the attendance at a college
volleyball game was 1,000. The actual attendance was
1,632. What is the percent error of Shaun's estimate?
Round to the nearest whole percent

Answers

Answer:

38.72%

Step-by-step explanation:

Estimated attendance = 1,000

The actual value of attendance = 1,632

We need to find the percent error of Shaun's estimate. Using the formula as follows :

[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]

Put all the values,

[tex]\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%[/tex]

So, the percent error of Shaun's estimate is 38.72%.

Danica is saving money to buy a used car in six months. She needs to save $1500 for a down payment in order to be able to finance the rest. She gets paid $180 per week at her part-time job. How much money will she need to save out of every weekly paycheck to reach her savings goal of $1500 in six months? Show the calculations:

Answers

Answer:

$62.5

Step-by-step explanation:

Step one:

Given data

Danica's goal is to save $1500

her pay is $180 weekly.

the duration is 6months

in a month we have 4 weeks

in 6months there are 6*4= 24 weeks

Step two:

In 24 weeks Danica's earnings will be 24*180= $4320

nevertheless, she only needs $1500 for the 24 weeks to make the down payment

So per week, she will need to save 1500/24= $62.5

When Katya factored 288, she listed these factors: 1, 2, 3, 6, 8, 9, 12, 16, 18, 32, 36, 48, 72, 96, and 288. Use a factor rainbow to decide which three factors she missed.

Answers

Answer:

Please find a representation of the factor rainbow below.

The missing factors are: 4, 24, and 144

Step-by-step explanation:

The factors of a number are those numbers that can divide another number without remainder. In this case where Katya factored 288, it means she listed the numbers that can divide 288 without reminder (factors of 288). However, among the factors she listed, THREE factors are missing.

To get the missing factors, we can use a FACTOR RAINBOW, which is a display of the factors of a number in a rainbow shape. The factors are arranged from smallest to largest number in such a way that the two numbers attached to a line can be multiplied to give the original number.

From the attached factor rainbow (see attached image), it can be observed that factors:  4, 24, and 144 are missing in the list of factors Katya provided.
