Does anyone know this?​

Answer:

[tex] \frac{3 - 3}{20 - 19} = \frac{0}{1} = 0 = m \\ \frac{ - 4 - 7}{ - 6 - ( - 4)} = \frac{ - 11}{ - 2} = \frac{11}{2} = m \\ \frac{8 - ( - 13)}{17 - 17} = \frac{21}{0} = und[/tex]

Answer:

1, 3, 5

Step-by-step explanation:

let the 3 consecutive odd numbers be n , n + 2 , n + 4 , then

5(n + 2) = 2(n + n + 4) + 3 ( 5 times 2nd = twice sum of 1st and 3rd + 3 )

5n + 10 = 2(2n + 4) + 3

5n + 10 = 4n + 8 + 3

5n + 10 = 4n + 11 ( subtract 4n from both sides )

n + 10 = 11 ( subtract 10 from both sides )

n = 1

n + 2 = 1 + 2 = 3

n + 4 = 1 + 4 = 5

The 3 consecutive odd numbers are 1, 3, 5

Step-by-step explanation:

let the three consecutive odd number be x + 1 , x + 3 , x + 5

a/q

5 times the middle number = 5(x + 3) is

3 more than twice the sum of 1st and 3rd number = 3 + 2(x+1 + x + 5 )

so,

= 5 ( x + 3 ) = 3 + 2 ( x + 1 + x + 5 )

= 5x + 15 = 3 + 4x + 12

= 5x + 15 = 4x + 15

= -4x + 5x = 15 - 15 = 0

= x = 0

so, the 3 consecutive odd numbers are,

x + 1 = 1

x + 3 = 3

x + 5 = 5

and also a/q

5 times the middle number = 5×3 = 15

is equal to 3 more than twice the sum of 1st and 3rd number = 3 + 2(1+5) = 12 + 3 = 15

LHS = RHS

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

f(x) = -3 when x = -1

Step-by-step explanation:

Let's go through this!

So our equation is f(x) = 2x - 1

we are asked for the value of f(x) when x = -1

Let's consider this, the f(x) value is the y value

and the x value in f(x) is the x value

So when x = -1

what is the y value?

we can use the equation to subsitute -1 into x and solve for f(x)

f(x) = 2(-1)-1

f(x) = -3

Our answer is -3

7k^3-3k^2+35k+21

Answer:

175%

Step-by-step explanation:

1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.

2. To find that percentage, we can write an equation of [tex]\frac{x}{100} * 4 = 7[/tex] because "of 4" means to multiply by 4, and "is 7" means that the product is 7.

3. Now, let's solve our equation.

Step 1: Simplify both sides of the equation.

Step 2: Multiply both sides by 25.

Step 3: Check to see if solution is correct.

Therefore, the answer is 175%.

Answer:

0.025

Step-by-step explanation:

Divide the percentage by 100 to convert it to decmals.

1/5 of 20 is 4

Answer:

24

Step-by-step explanation:

Since the lines L and M are parallel:

Angle 1 and and 2 are alternate and their measurement is equal.

3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)

6 + 12 = 6x - 3x

18 = 3x divide both sides by 3

6 = x to find the angle measure replace x with 6

3x + 6 is 3*6 +  6 = 24

Answer:

The solution is A. (-2,7) and C. (3,2)

Step-by-step explanation:

x+y = 5 ............(1)

x²+y = 11 ............(2)

_________________________

y = 5-x

x²+(5-x) = 11

x²+5-x-11 = 0

x²-x-6 = 0

x²+2x-3x-6 = 0

(factor statement)

x(x+2)-3(x+2) = 0

(x+2) (x-3) = 0

x+2=0 x-3 =0

x = -2 x = 3

(x1 = -2, x2 = 3)

_________________________

y = 5-x

y = 5-(-2) ............(1)

= 7

y = 5-3 ............(2)

= 2

(y1 = 7, y2 = 2)

_________________________

(x1,y1) & (x2,y2)

(-2,7) & (3,2)

So, A. (-2,7) and C. (3,2) correct

Answer:

Simplifying

4x + -6 = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(3 + 2x)

-6 + 4x = (3 * 2 + 2x * 2)

-6 + 4x = (6 + 4x)

Add '-4x' to each side of the equation.

-6 + 4x + -4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 + 0 = 6 + 4x + -4x

-6 = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 = 6 + 0

-6 = 6

Solving

-6 = 6
