Answer:

y = -1/2x - 4

Step-by-step explanation:

To find the inverse of a linear function, simply switch the x and y positions. Solve for y.

y = -2x - 8

x = -2y - 8

x + 8 = (-2y - 8) + 8

x + 8 = -2y

(x + 8)/-2 = (-2y)/-2

-1/2x - 4 = y

y = -1/2x - 4

I NEED HELP PLS I WILL MARK BRAINLIEST

ANEK [815]

Answer:

$\approx 11.2\:\mathrm{in}$

Step-by-step explanation:

The swing of the tip of pendulum is creating an arc. The question is actually asking for the length of this arc. The length of an arc is given by $2r\pi\cdot \frac{\theta}{360}$ , where $r$ is the radius of the circle and $\theta$ is the angle of the arc.

In this problem, we're given:

$\theta = 40^{\circ},\\r=16$

Substituting given values, we get:

$2\cdot 16\cdot \pi \cdot \frac{40}{360}=32\pi\cdot \frac{1}{9}\approx \boxed{11.2\:\mathrm{in}}$

Mrs. Duncan measured the lengths of a crayon and a pencil. The pencil is double the length of the crayon. The sum of their lengt

Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon = $x$

Length of a pencil = $2x$

As according to question that the sum of their length is 24 centimetres

So we have

$x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8$

Therefore the length of crayon = 8 centimetres

Length of pencil= $2x= 2\times x = 2\times 8 =16$ centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
