Please help<br> Me<br> Quick
Mrac [35]

Answer:

5

Step-by-step explanation:

First figure out the equation:

We know this is a linear equation because it appears to have a constant slope

Its y-intercept is where it passes in the y-axis, so it's -8

Furthermore, you should also figure out the slope. Notice that the y value increments by 3 every 1 x-value. Rise/Run is 3/1 = 3. Thus, the slope is 3

So your equation is g(x) = 3x - 8

Now we find our inverse function, which is just swapping the x-y values.

Thus, inverse of g(x) ==>  y = 3x - 8 ==> x = 3y - 8 ==>  x+8 = 3y ==> \frac{x+8}{3}

Plug in 7 for x and you get 5

Maggie's brother is 9 years younger than three times her age. The sum of their ages is 43. How old is Maggie?
bekas [8.4K]

Answer:

Maggie's age is 13 years

Step-by-step explanation:

Let

x ------> Maggie's brother age

y ------> Maggie's age

we know that

x+y=43 ------ > equation A

x=3y-9 ------> equation B

substitute equation B in equation A and solve for y

(3y-9)+y=43

4y=43+9

4y=52

y=13

therefore

Maggie's age is 13 years

In an obstacle course, participants climb to the top of a tower and use a zip line to travel across a mud pit. The zip line exte
barxatty [35]

Using relations in a right triangle, it is found that the length of the zip line is of 40.4 feet.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

This situation can be modeled by a right triangle, in which the extension of the zip line of 48.2 feet is the hypotenuse and the length is the adjacent side to the angle of 33º, hence:

\cos{33^\circ} = \frac{l}{48.2}

l = 48.2 x cos(33º)

l = 40.4.

The length of the zip line is of 40.4 feet.
