Answer:

I'm sorry if it's worng but I think it's A

Answer: a- 1

Step-by-step explanation:

Step-by-step explanation:

the slope = 5/3

through (1, -1)

the equation :

y -(-1) = 5/3 (x -1)

y+1 = 5/3 x -5/3

y = 5/3 x -5/3 -1

y = 5/3 x - 8/3 or y = 5/3 x - 2⅔

Answer

1. f - 3/4

2. 62 + h

Step-by-step explanation:

1. 1/4 of the fish are angelfish, all fish are one whole, one whole - 3/4's = 1/4

2. we dont have the value of H so we in turn have to figure out the equation and 62 + h is the only answer we can come to

i do know the answewr and it is b because the irrational product is negative 6

Answer:

1) [tex]\frac{x+3}{2x-5}=\frac{3}{2}[/tex]   (x ≠ 2,5)

=> 2(x + 3) = 3(2x - 5)

⇔ 2x + 6 = 6x - 15

⇔ 4x = 6 + 15

⇔ 4x = 21

⇔ x = 5,25

2) [tex]\frac{5y-2}{2y+8}=\frac{5}{6}[/tex] (y ≠ -4)

⇒6( 5y - 2) = 5(2y + 8)

⇔30y - 12 = 10y + 40

⇔ 20y = 52

⇔ y = 2,6

3) the denominator of the rational number is x (x ≠ 0)

because the denominator is greater than the numerator by 6

=> the numerator is x - 6

If the numerator is decreased by 1 and the denominator increased

by 1 , the number obtained is 1/3. so we have:

[tex]\frac{x-7}{x+1}=\frac{1}{3}[/tex]

⇒ 3(x - 7) = x + 1

⇔ 3x - 21 = x + 1

⇔ 2x = 22

⇔ x = 11

with x = 11 => the rational number is 5/11

4) the number we need to find is ab (a ≠ 0)

because Sum of the digits of this number is 8

=> a + b = 8 (*)

When we interchange  the digits , it is found that the resulting new number is less than the  original number by 18, we have:

ab - ba = 18

⇔ 10a + b - (10b + a) = 18

⇔ 9( a - b) = 18

⇔ a - b = 2 (**)

(*)(**) => a + b = 8

             a - b = 2

=> a = 5

    b = 3

=> the original number is 53

5) the present Arjun's age is x (years old)( x, y E N*)

the present Shriya's age is y

because now, Arjun is twice as old as Shriya => x = 2y

Five years ago, his age was three  times Shriya’s age, we have:

=> x - 5 = 3(y - 5)

⇔ x - 5 = 3y - 15

⇔ 3y - x = 10

but x = 2y => y = 10

=> x = 20

so now, Arjun is 20 years old, Shriya is 10 years old

Answer: $535

Step-by-step explanation

He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):

So the formula for interest is

Interest = (principal ×interest rate × time for which the money was deposited) / 100

Interest = ?

Principal = $500

Interest rate = 7%

Time = 1 year

Now

Interest = (500 × 7 × 1) / 100

Interest = 3500/ 100

Interest = $35

So the refrigerater's cost = 500 + 35

Cost = $ 535

Answer:

104 = 10,000 x 1.3 = 13,000

Step-by-step explanation:

step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 13,000

New Number: 1.3000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 3 0 0 0

Decimal Count:   1 2 3 4

There are 4 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.3 (Please notice any zeroes on the end have been removed)

b = 4

Now the whole thing:

1.3 x 104

Step 4

Check your work:

104 = 10,000 x 1.3 = 13,000

The graph of a function gives the set of a ordered pair of the function

Pease find attached and included the appearance of the graph and table of values of the given function f(x) = 2·x³ - 7·x² + 2·x + 3

The given function is presented as follows;

f(x) = 2·x³ - 7·x² + 2·x + 3

Required:

To find the graph that represents the given function

Solution:

From the given function, at x = 0, we have;

f(0) = 2 × 0³ - 7×0² + 2×0 + 3 = 3

Therefore, at x = 0, f(x) = 3, and a  point on the graph is the point (0, 3)

At x = 1, f(x) = 2 × 1³ - 7×1² + 2×1 + 3 = 0 therefore, a graph point is (1, 0)

At x = 0.5, f(x) = 2 × 0.5³ - 7×0.5² + 2×0.5 + 3 = 2.5 therefore, a graph point is (0.5, 2.5)

With the above function, the following table can be obtained

[tex]\begin{array}{|c|cc|}\mathbf{x}&&\mathbf{y}\\-1&&-8\\-0.5&&0\\0&&3\\0.5&&2.5\\1&&0\\1.5&&-3\\2&&-5\\2.5&&-4.5\\3&&0\\3.5&&10\end{array}\right][/tex]

From the above table of values, the graph of the function can be drawn as shown in the attached diagram created with MS Excel

HP

Answer:

see explanation

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1

Consider left side

(2sinx + 3cosx)² + (3sinx - 2cosx)² ← expand parenthesis using FOIL

= 4sin²x + 12sinxcosx + 9cos²x + 9sin²x - 12sinxcosx + 4cos²x

Collect like terms

= 13sin²x + 13cos²x ← factor out 13 from each term

= 13(sin²x + cos²x)

= 13 × 1

= 13

= right side , thus proven
