Answer:

69

Step-by-step explanation:

We are given the expression:

\displaystyle \large{10y - 7z}

Evaluate the expression when y = 9 and z = 3; substitute y = 9 and z = 3 in the expression.

\displaystyle \large{10(9)- 7(3)} \\  \displaystyle \large{90- 21} \\  \displaystyle \large{69}

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 2l + 2w=16, where l re
cricket20 [7]
2l + 2w = 16   
2(l+ w)  = 16    Divide both sides by 2
l + w =  16/2

l + w  =  8

So for example the length l could be 5 and the width could be 3.
Length could be 5.

Which set of ordered pairs represents a function?
mel-nik [20]
The one that doesn't have an "x" repeated, that is an X-REPEAT
notice, the pair is just an x,y  pair.. .so if the "x" is repeated, is NOT a function

let's see

\bf \{(2, -2), (\boxed{1}, 5), (-2, 2), (\boxed{1}, -3), (8, -1)\}\impliedby \textit{has an "x" rep}eated\\\\
\{(3, -1), (7, 1), (-6, -1), (9, 1), (2, -1)\}\\\\
\{(6, 8), (5, 2), (\boxed{-2}, -5), (1, -3), (\boxed{-2}, 9)\}\impliedby \textit{has an "x" rep}eated\\\\
\{(\boxed{-3}, 1), (6, 3), (\boxed{-3}, 2), (\boxed{-3}, -3), (1, -1)\}\impliedby \textit{an "x" rep}eated

What’s the domain and range?<br><br> An airplane travels at 565 mph.
viktelen [127]

Answer:

<u>Domain:</u>

The domain of this can be any value between 0 to 565 miles per hour

<u>Range:</u>

The reasonable range can be the distance traveled which can be from 0 to 13,560 miles (no plane travel is longer than 24 hours, we assume).

Step-by-step explanation:

Domain is the input, set of x values for the function.

Range is the output, set of y values for the function.

This isn't a function essentially, but it is given that an Airplane travels at 565 miles per hour.

<em>We can say that the domain will be the speed of the airplane and the range would be the distance it travels.</em>

<em />

<u>Domain:</u>

The domain of this can be any value between 0 to 565 miles per hour

<u>Range:</u>

The reasonable range can be the distance traveled which can be from 0 to (565*24=13,560 miles) 13,560 miles (no plane travel is longer than 24 hours, we assume).
