find the slope of the line through each pair of points (1/2,0) and (0,4/7)

Answer:

7

3 times ? - 11

=

? + 3

? = 7

Step-by-step explanation:

3 times 7 is 21 -11 is 10

7+3 is 10

Both equations has to make 10 so it is the answer of 7

Hope this helps :)

Answer:

[tex]\boxed{x=7 }[/tex]

Step-by-step explanation:

3x - 11 = x + 3

→ Minus x from both sides to isolate the 'x's

2x - 11 = 3

→ Add 11 to both sides to isolate 2x

2x = 14

→ Divide both sides 2 to isolate x

x = 7

Answer:

b  > 250/9 and w ≥ 0

Step-by-step explanation:

7/9 (b - 27) > 49/81

First, simplify both sides of the inequality:

7/9b - 21 > 49/81

Add 21 to both sides

7/9b - 21 +21 > 49/81 +21

Multiply both sides by 9/7

9/7 x 7/9b > 49/81 x 9/7

b > 1750/81

Simplify

b > 250/9

11w - 8w ≥ 14w

Simplify both sides once again

3w ≥ 14w

Subtract 14w from both sides

3w - 14w ≥ 14w - 14w

-11w ≥ 0

Divide both sides by -11w

w ≥ 0

Answer:

4. 7/9 (b - 27) > 49/81

=> 7/9b - 21 > 49/81

=> 7/9b - 21 > 7/9

=> 7/9b -21 + 21 > 7/9 + 21

=> 7/9b > 7/9 + 189/9

=> 7/9b > 196/9

=> 7/9b / 7/9 > 196/9 / 7/9

=> To divide fractions, take the reciprocal of the divisor fraction and then multiply.

=> b > 196/9 x 9/7

=> b > 1764 / 63

=> b > 28

4th answer is b > 28

5. This question doesn't make any sense.

=> 11w - 8w greater or equal to 14w

=> 3w greater or equal to 14w.

If we make "w" as any number, this equation will not come true as 14 is larger than 3.

This answer may be correct the equation is like:

3w is smaller or equal to 14w.

Answer:

-6

Step-by-step explanation:

In an arithmetic sequence, the common difference is the difference between each number in the sequence.

In this sequence, the common difference is -6 because from left to right, we can see that the numbers decrease by 6 each time.

For example, 12 - 6 = 6.

Answer:

every step you subtract 6 so the common difference is -6

Answer:

[tex]A=135.37\ \text{inch}^2[/tex]

Step-by-step explanation:

Given that,

Radius of circle, r = 19 inch

Angle with sector, [tex]\theta=135^{\circ}[/tex]

We need to find the area of the sector.

The formula is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{135}{360}\times \pi (19)^2\\\\A=135.37\ \text{inch}^2[/tex]

So, the area of the sector is [tex]135.37\ \text{inch}^2[/tex].

Answer:

x = 3

Step-by-step explanation:

3(2x + 5) = 33

3 * 2x + 3 * 5 = 33

6x + 15 = 33

6x = 33 - 15

x = 18 / 6

x = 3

Answer:

Step-by-step explanation:

Let the number be x

The statement

twice a number is written as

2x

The sum of twice a number and seven is written as

2x + 7

The result is 13

So we have

2x + 7 = 13

Subtract 7 from both sides

That's

2x + 7 - 7 = 13 - 7

2x = 6

Divide both sides by 2

That's

[tex] \frac{2x}{2} = \frac{6}{2} [/tex]

We have the final answer as

x^15/x^8 = x^7

x^3⋅x^4 = x^7

(x^21)1/3 = x^7

Step-by-step explanation:

The equivalent expressions of expression x⁷ are (x²¹)¹/³, x⁷ and x¹⁵/x⁸.

Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).

Given:

An expression x⁷.

To find the equivalent expressions:

(1).

(x²¹)¹/³

Simplifying,

= ∛(x⁷)³

= x⁷

This is an equivalent expression of expression x⁷.

(2).

x¹⁵/x⁸

Simplifying,

= x⁸⁺⁷/x⁸

= x⁷

This is an equivalent expression of expression x⁷.

(3).

x¹³ / x²¹

Simplifying,

= x¹³/x¹³⁺x⁸

= 1/ x⁸

This is not an equivalent expression of expression x⁷.

(4).

x³ / x⁴

Simplifying,

= 1/ x

This is not an equivalent expression of expression x⁷.

(5).

x¹⁵ x⁸

Simplifying,

= x²¹

This is not an equivalent expression of expression x⁷.

(6).

x³x⁴

Simplifying,

= x⁷

This is an equivalent expression of expression x⁷.

Therefore, the equivalent expressions are (x²¹)¹/³, x⁷ and x¹⁵/x⁸.

Answer:

x4-x3-2x2-4x+12

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)

=> x4-4x2+4-(x3-2x2+4x-8)

=> x4-4x2+4-x3+2x2-4x+8

=> x4-x3-2x2-4x+12

The value of the function (f-g)(x) is [tex]x^4-x^3-2x^2-4x+12[/tex].

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given functions are [tex]f(x)=x^4-4x^2+4[/tex] and g(x)=x³-2x²+4x-8.

Now, (f-g)(x)=f(x)-g(x)

= ([tex]x^4-4x^2+4[/tex])-(x³-2x²+4x-8)

= [tex]x^4-4x^2+4[/tex]-x³+2x²-4x+8

= [tex]x^4-x^3-2x^2-4x+12[/tex]

Therefore, the value of the function (f-g)(x) is [tex]x^4-x^3-2x^2-4x+12[/tex].
