Answer:

(a) Output = 37

(b) Input = 9

Step-by-step explanation:

Given

$y =x5 - 3$

Solving (a): Output, when input = 8

This means that, we solve for y when x = 8

So, we have:

$y =x5 - 3$

$y =8*5 - 3$

$y =40 - 3$

$y = 37$

Solving (b): Input, when output = 42

This means that, we solve for x when y = 42

So, we have:

$y =x5 - 3$

$42 = x5 - 3$

Collect like terms

$x5 = 42 + 3$

$x5 = 45$

Divide both sides by 5

$x = 9$

Sylvia read that the height of the Empire State Building is 443.2 m and wants to build a scale model of the building in her room

Answer:

Scale of 181: 1

Step-by-step explanation:

The first thing to do is to pass the feet by the meter, to work in the same units and thus create a consistent scale:

We know that one foot equals 0.3048 meters, therefore:

8 feet * 0.3048 meters / 1 foot = 2.4384 meters

So the scale would be:

443.2 / 2.4384 = 181.75

Which means that it is best to make a scale of 181: 1

Where 181 meters from the Empire State Building would equal 1 meter at home 0 181 inches would equal 1 inch at home

can someone help me with this. its called identifying angle relationships in parallel lines, but like solve them or something on

likoan [24]

Here, The relation between two angles is alternate exterior angles. And we know that alternate interior angles are equal, Let's find the value of x with the help of this statement...

$\red{{ : } \implies} \blue{ \sf16x + 22 = 134}$

$\red{{ : } \implies} \blue{ \sf16x = 134 - 22}$

$\red{{ : } \implies} \blue{ \sf16x = 112}$

$\red{{ : } \implies} \blue{ \sf \: x = 7}$
