Colin was thinking of a number. Colin adds 10, then divides by 6 to get an answer of -8. What was the original number?

Answer:

∠BCD=95°

Step-by-step explanation:

∠B+∠D=127+43=170

360-170=190

∠A=∠C

∠A+∠C=190

∠C+∠C=190

∠C=190/2=95°

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b  has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x =  m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b)  = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.

A

Answer:

Step-by-step explanation:

Given function in the question is,

[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]

       [tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]

       [tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]

Given function is not defined at x = -2

At x = -2,

[tex]f(-2)=\frac{1}{2}(2)[/tex]

          [tex]=1[/tex]

Therefore, there is a hole in the graph at (-2, 1).

Graph of the function 'f' will be a straight line with a hole at (-2, 1).

Horizontal asymptote → None

Vertical asymptote → None

x-intercept → No x-intercept [Line passes through origin (0,0)]

y-intercept → No y-intercept [Line passes through origin (0,0)]

Hole → (-2, 1)

Answer:

X=4, y=5

Step-by-step explanation:

5x + 4y =40 equation 1

6x + 4y =44 equation 2

-1(5x + 4y)=-1(40) multiply equation 1 by -1 so equation will eliminate y

-5x - 4y=-40 modif equation 1

6x + 4y= 44  equation 2

         x=4.     Add above 2 equations

solve for y:

5x + 4y =40

5(4)+4y=40

20+4y =40

4y=20

y=5

check solution ;

6x+4y=44

6(4) + 4(5)=44

24 + 20=44

44=44

Answer:

The length of side PQ is 2 units.

The length of side QR is 2.24 units.

The perimeter of the parallelogram PQRS is about 8.48 units.

Step-by-step explanation:

The given figure is as follows :

To find - The length of side PQ is ....... units.

              The length of side QR is about ......... units.

               The perimeter of the parallelogram PQRS is ........

Solution -

From the figure , we can see that

P = (-5, 3)

Q = (-3, 3)

R = (-4, 1)

S = (-6, 1)

Now,

By distance formula, we get

PQ = √(3 - 3)² + (-3 + 5)²

     = √0 + 2²

     = √4

     = 2

∴ we get

The length of side PQ is 2 units.

Now,

QR = √(1 - 3)² + (-4 + 3)²

     = √(-2)² + (-1)²

     = √4 + 1

     = √5

     = 2.236

∴ we get

The length of side QR is 2.24 units.

Now,

We know that,

Perimeter of Parallelogram = 2(a + b) where a is the base and b is the side

Here Given that,

a = 2

b = 2.24

So,

Perimeter of parallelogram PQRS = 2(2 + 2.24)

                                                         = 2(4.24)

                                                         = 8.48

∴ we get

The perimeter of the parallelogram PQRS is about 8.48 units.

Answer:

PQ 2 units

QR 2.24 units.

Answer:

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Step-by-step explanation:

The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:

[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Initial point.

[tex]B(x,y)[/tex] - Terminal point.

If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:

[tex]\vec v = (-3,1) -(-5-5)[/tex]

[tex]\vec v = (2, 6)[/tex]

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Step-by-step explanation:

Answer:

Option D.

Step-by-step explanation:

We have the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

First, let's  try to isolate x in one side of the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

(5/2)*x ≥ 2*x - 13/2 - 3

(5/2)*x - 2*x ≥  - 13/2 - 3

Now all the terms with an x are in the left, and the terms without are in the right.

We can rewrite this inequality as:

(5/2)*x - (4/2)*x ≥  - 13/2 - 6/2

(1/2)*x ≥ -19/2

Now, multiplying both sides by 2 we get:

2*(1/2)*x ≥ (-19/2)*2

x ≥ - 19

So the graph will be a solid point in x = -19, and a ray that extends to the right (the values that are larger than -19)

The correct option is the last graph, option D.
