Answer:

x = 13

Step-by-step explanation:

a^2 + b^2 = c^2

5 = a     12 = b

5^2 + 12^2 = c^2

25 + 144 = c^2

c^2 = 169

square root of 169 = 13

Given:

  [tex]f(x)=\dfrac{1}{8}x^3\\\\g(x)=2x^{\frac{1}{3}}[/tex]

We find that ...

  [tex]f(g(x))=\dfrac{1}{8}(2x^{\frac{1}{3}})^3=\dfrac{1}{8}(2^3)(x^{\frac{3}{3}})=\dfrac{8}{8}x\\\\\boxed{f(g(x))=x}\\\\g(f(x))=2\left(\dfrac{1}{8}x^3\right)^{\frac{1}{3}}=2\left(\dfrac{1}{8^{\frac{1}{3}}}\right)(x^{\frac{3}{3}})=\dfrac{2}{2}x\\\\\boxed{g(f(x))=x}[/tex]

x = - 6

y = - 2

-3x + 5y = 8  | ×(-2)

-2x + 7 y = -2​ | ×3

6x - 10y = - 16

- 6x + 21y = - 6

add

6x - 6x - 10y + 21y = - 16 - 6

11y = - 22

y = - 22 : 11

y = - 2

replace y

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

- 2x - 14 = - 2

- 14 + 2 = 2x

2x = - 12

x = - 12 : 2

Answer: y = - 1

Step-by-step explanation:

Answer:

y = -1

Step-by-step explanation:

-16y - 7y + -5 = 18

~combine like terms

-23y + (-5) = 18

~add 5 to both sides to get -23y by itself

-23y = 23

~divide by 23 on both sides to get just y by itself

-1 = y

Answer:

Two angles are said to be vertical angles if and only if their sides form two pairs of opposite rays.

Step-by-step explanation:

A biconditional statement is one that must fulfill the two conditions of the statement for it to be true. The two required conditions in the statement are always connected by if and only if.

The required statement is: Two angles are said to be vertical angles if and only if their sides form two pairs of opposite rays

Vertical angles are equal and opposite. Therefore for the biconditional statement to be true, the angles should be vertical and their sides must form two pairs of opposite rays.

6(2x -3) - 8 = -2 (remove the parantheses)

12x - 18 - 8 = -2 (calculate)

12x - 26 = -2 (move the constant to the right)

12x = -2 + 26 (calculate)

12x = 24 (divide both sides)

x = 2

Answer:

  The initial values of the two functions are different and the rates of change of the two functions are the same

Step-by-step explanation:

In order for output values to always be different, the two linear functions must describe parallel lines. That means the rates of change are the same, but the initial values are different.

Answer:

y= -4x-7 or 4x+y= -7

Step-by-step explanation:

we know y=mx+c

given,

m=-4 c=-7

the equation y= -4x-7 or 4x+y= -7

thank u

Answer:

y=-4x-7

Step-by-step explanation:

Hi there!

We are given that the slope of a line is -4, and the y intercept of this same line is -7

We want to write the equation of this line in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept, hence the name

As we are given the values for both the slope and the y intercept of this line, we can immediately substitute those values into the equation

Let's start with the slope; substitute -4 as m in the equation

y=-4x+b

Now with the y intercept; substitute -7 as b into the equation

y = -4x - 7

Answer: The answer is skew!

Step-by-step explanation:h

When lines are not parallel, and they do not intersect, such lines are said to be skewed.

Line AC and RS are skew.

From the diagram, we have two planes.

Line AC is on plane x, while line RS is on plane y

Plane x and plane y are not parallel;

So lines AC and RS are not parallel.

Also, both lines are not parallel.

Using the condition of skewness stated above, we can conclude that line AC and RS are skew.
