Answer:

27/28

Step-by-step explanation:

You would have to find the LCM of 4 and 7, which is 28. Then you multiply the numerators by the same number you multiplied on the denominator. You would then get 1 7/28 - 8/28 = 35/28 - 8/28 = 27/28.

Step-by-step explanation:

Answer:

X = 1

Step-by-step explanation:

-2x + 7 = 3 - ( -2x)

-2x + 7 = 3 +2x (- - = +) (+ + = +) and (different signs always negative: - + = -)

(any term or numbers moved from one side of the = sign goes from negative to positive or from positive to negative, from multiplying to dividing and from dividing to multiplying. First isolate the additions or subtractions.)

-2x + 7 = 3 + 2x

-2x + 7 - 3 = 2x

-2x + 4 = 2x

4 = 2x + 2x

4 = 4x (a number next to a letter is multiplying. It goes to the other side of the equation dividing)

4 /4 = x

X = 1

-2x + 7 = 3 - (-2x)

-2x + 7 = 3 + 2x

-2x - 2x = 3 - 7

-4x = -4

x = 1

Answer:

the option d is the correct answer

IH + HJ = 2 (IH)

0.75 + HJ = 2(0.75)

0.75 + HJ = 1.5

HJ = 1.5 - 0.75

HJ = 0.75

Answer:

b: y=2x-5

Step-by-step explanation:

Y = MX + B

Slope = M

B = y-intercept

Judging by the image the function graphed has an asymptote at x = 3 and extends forever to -infinity along the x axis.

so the answer would be - infinity not included (because infinity is a concept not a number) to +3 not included because the function infinitely approaches x = 3. this is (-∞,3) in interval notation.

Answer:

answer of n is 15 by pythagoras theorem

Step-by-step explanation:

n is a hypotenuse

[tex] \sqrt{ {12}^{2} + {9}^{2} } = 15[/tex]

Answer:

Given coordinates on the graph is (4,0), (8,10), (12,20).

We need to find the rate of change for the function graphed.

Actually rate of change is the second name of slope.

So, we need to find the slope between given coordinates.

We know slope formula

Let us choose first two coordinates (4,0), (8,10).

(x1,y1) = (4,0) and (x2,y2) = (8,10).

Plugging values of x1,x2,y1 and y2 in slope formula, we get

Slope=

Therefore, rate of change is 5/2 or $2.5 earned per bookmark sold.

Answer:Calculate the Land Transfer Tax on a house for 248000

   Calculation example

1.multiply $55,000 by 0.5% (55,000 × 0.005) = $275.

2.multiply the amount exceeding $55,000 up to $250,000 by 1.0% (195,000 × 0.01) = $1,950.

3.multiply the amount exceeding $250,000 up to $400,000 by 1.5% (150,000 × 0.015) = $2,250.

Answer:

Chunking is best for smaller numbers and arithmetic. Short division is great for dividing larger numbers by one digit numbers. Long division is handy for dividing large numbers by numbers with 2 or more digits.

Answer:

x= 1.36

Step-by-step explanation:

Answer:

Step-by-step explanation:

5(x−2 2/5) = −5.2

1. We need to use distibutaive property

5×x and 5×-2.4

5x - 12 = -5.2

2. We need to get x alone.

5x - 12 = -5.2

    -12      -12

5x = 6.8

3. We need to divide

5x = 6.8

/5     /5

x = 1. 36

check:

5(1.36−2 2/5)=−5.2

6.8 - 12 = 5.2

[a] If the total is 450 and Gavin (g or y) earned 50 more than Seiji (s or x) then we can create the following system:

{ s + 50 = g

{ g + s = 450

[b] See attached

[c] Gavin earned $250 and Seiji earned $200

    Using the graph, we will look at where the points intercept. The x will be Seiji, and the y will be Gavin. Using this, we can see the answer is (200, 250) leaving Seiji with 200 dollars and Gavin with 250 dollars

    (there is also a simpler way to do this, but as I was following the assignment I think this is what you need!)

Have a nice day!

Equation at the end of step 1

STEP

:

Trying to factor by splitting the middle term

2.1     Factoring  8x2-6x-3  

The first term is,  8x2  its coefficient is  8 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   8 • -3 = -24  

Step-2 : Find two factors of  -24  whose sum equals the coefficient of the middle term, which is   -6 .

     -24    +    1    =    -23  

     -12    +    2    =    -10  

     -8    +    3    =    -5  

     -6    +    4    =    -2  

     -4    +    6    =    2  

     -3    +    8    =    5  

     -2    +    12    =    10  

     -1    +    24    =    23  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 8x2 - 6x - 3

Answer:

241,400,000

Step-by-step explanation:

200,000,000×100÷2.3= 4,600,000

2022-2013= 9

4,600,000×9= 41,400,000

200,000,000 + 41,400,000 = 241,400,000

Answer:

241,400,000

Step-by-step explanation:

200,000,000×100÷2.3= 4,600,000

2022-2013= 9

4,600,000×9= 41,400,000

200,000,000 + 41,400,000 = 241,400,000

Answer:

Max value: 9

Max x value: -2

Step-by-step explanation:

We're trying to find the vertex of y = 5 - 4x - x²

We can try to convert this equation to vertex form

First, subtract 5 from both sides

y = 5 - 4x - x²

- 5  -5

y - 5 = -4x - x²

Then add -4 to both sides (this is because this the sqaure of half b -4)

y - 5 - 4 = -4x - x²+ 4

y - 9 = -4 - 4x - x²

Factor the right side of the equation

y - 9 = -(x + 2)(x + 2)

y - 9 = -(x + 2)²

Add 9 to both sides

y - 9 = -(x + 2)²

 + 9      + 9

y = -(x + 2)² + 9

To find the max values we have to make it to where x + 2 = 0

x + 2 = 0

  - 2     - 2

x = - 2

When we make equation inside the parenthesis 0, we get y = 9

y = -(-2 + 2)² + 9

y = -(0)2 + 9

y = 9

Answer:

1 2/3

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{8}{5}[/tex]

Applying the fractions formula for division,

= [tex]\frac{8}{3} x \frac{5}{8}[/tex]

=[tex]\frac{40}{24}[/tex]

Simplifying 40/24, the answer is

1[tex]\frac{2}{3}[/tex]

Answer:

  c = -3; d = 5

Step-by-step explanation:

The function is differentiable if it is continuous and the derivative is continuous.

This function will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...

  5(3^2) +c = 45 +c

From the right, the limit is ...

  d(3^2) -3 = 9d -3

__

The derivative will be continuous if the limit as x approaches 3 from either side is the same. From the left, the limit is ...

  f'(x) = 10x

  = 10(3) = 30

From the right, the limit is ...

  f'(x) = 2dx

  = 2d(3) = 6d

__

This gives us a pair of simultaneous equations in 'c' and 'd':

  45 +c = 9d -3

  6d = 30

The latter tells us d = 5. Then the former tells us ...

  45 +c = 9(5) -3   ⇒   c = -3

The function is differentiable if c = -3 and d = 5.

With these values, the function becomes ...
