Answer:

The midpoint is (2.5,-6) or written as a fraction ([tex]\frac{5}{2}[/tex], -6)

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2} ) \\MP= (\frac{-2+7}{2}),(\frac{-8+-4}{2} ) \\MP= (\frac{5}{2}),(\frac{-12}{2} ) \\MP= (2.5,-6 )[/tex]

Answer:

4

Step-by-step explanation:

solution: −√10<x<−2 or 2<x<√10

√10=3.16

-3,-2,2,3

The 2 and -2 are the integers satisfy the inequality.

It is required to find the number of integers .

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

Given:

For (x²– 4)< 0;

x²<4

By taking the square root of both sides we have,

√x²<√4

x < ±2

x<2 and x<-2

Also,

x²<10

By taking  the square root of both sides we get,

√x²<±√10

x < ±√10

x<√10 and x<-√10

The √10 is not an integer but an irrational number. An integer  is a whole number (not a fractional number) that can be positive, negative, or zero.

So we can't take the integer of ±√10.

Therefore, the 2 and -2 are the integers satisfy the inequality.

Answer:

2(x + 1) = 8x - 5

assuming you already made the first step, the next step is to distribute the 2

2x + 2 = 8x - 5

if you havent made the first step, above is the first step.

the second step would be to combine like terms by subtracting 2x and adding 5 to both sides

7 = 6x

then you would divide both sides by 6

x = 7/6

Answer:

7/3

Step-by-step explanation:

y2-y1/x2-x1

-2-(-9)/6-3 = -2+9/3 = 7/3

To find the midpoint, we must take the sum of both values and then divide by two.

In this case, our values are -6 and 14

-6 + 14 = 8

8 / 2 = 4

B is located at 4 on the number line.

Step-by-step explanation:

Answer:

1. x/4

2. 2/3+x

3. 9-n

Step-by-step explanation:

1. "A number" is an unknown value, so we set that as the variable. When a number is being divided, it's the divisor in a division problem (the first number)

2. The "sum" is the answer to an addition problem (like how the "quotient" is the answer to a division problem), which is why we know to add. Again, "a number" is the unknown value so we set that as the variable.

3. Because Drew is "n" years younger than Joe, Joe's age - n = Drew's age. The question tells us that Joe is 9 years old, so the expression would be 9-n.

Answer: He can make 16 batches of cookies.

Step-by-step explanation:

Given: . To make cookies, Joshua  needs[tex]1\dfrac18[/tex] cups of flour per batch of cookies.

i.e. 1 Batch requires =[tex]1\dfrac18[/tex] cups of flour

=[tex]\dfrac{9}{8}[/tex] cups     [convert mixed fraction to improper fraction.]

Now if 1 batch = [tex]\dfrac{9}{8}[/tex] cups     (i)

Then, 1 cup = [tex]\dfrac{8}{9}[/tex] batch.           (ii)              [Multiply (i) by [tex]\dfrac{8}{9}[/tex]  ]

Joshua has 18 cups of flour.        

That means ,   18 cup = [tex]18\times\dfrac{8}{9}=2\times8=16[/tex] batch.   [Multiply (ii) by 18]

∴ He can make 16 batches of cookies.

Answer:Step 1: Simplify both sides of the equation.

Answer:

D-246 pages.

Step-by-step explanation:

To find the total number of pages, you must do 3*410 which = 1,230. 1,230 is the total number of pages so then you divide that by 5 because there are 5 days so 1,230/5 = 246. So 246 pages per day.

ANSWER 246

410*3(books)=1230 /5(days) =246

Answer:

less than 5

x < 5

Answer:

for first car

c = 250 + 0.02*$115,075 = 2551.5

for second car

c= 250 + 0.02*$21,640 = 682.8

total commission= 2551.5 +682.8 = 3234.3

We need to find the area of the hallway. To find the area of a rectangle, simply multiply the length and width together.

6ft * 18ft = 108^ft

Now, let's find the area of the square tiles. To find the area of a square, simply square one side.

(2/3ft)^2 = 4/9ft^2

To find out how many square tiles are necessary to tile the hallway, lets divide the area of the hallway by the area of one square.

108ft^2 / (4/9ft^2) = 243 tiles

Answer:

7 x 10^4

Step-by-step explanation:

4 x 10^2 equals to 400, when 7 x 10^4 equals to 70,000

Answer:

[tex]7[/tex]× [tex]10^{4}[/tex]

Step-by-step explanation:

Because the exponent means that the number is being multiplied by itself that many times. Like [tex]10^{4}[/tex] means 10000 and that times 7 is 70000.

[tex]10^{2}[/tex] would be 100 and 100 times 4 is 400. Now to determine is 400 or 70000 larger? 70000 is larger.

Hope that helps and have a great day!
