Hey there! :)
2x - 3y - z ; When x = -2, y = 3, & z = -2
Since we're given the values of x, y, & z, we can very simply plug everything in!
2(-2) - 3(3) - (-2)
Simplify.
(-4) + (-9) + 2
Get rid of parenthesis.
-4 - 9 + 2
Remember to do PEMDAS!
Parenthesis
Exponents
Multuply
Divide
Add
Subtract
So, since adding comes before subtracting, let's add! :)
-4 - 9 + 2
-4 - 7
Simplify.
-11
So, our answer is [A] : -11
~Hope I helped!~
B. Because a domain is the "x" value and on a graph you would notice the the "x" are all positive numbers (to the left). Hope that made sense. A range is the "y" value and are negative numbers (to the right) on a graph just in case you would like to know that as well:)
Answer:
A) 49x^2-36 km
Step-by-step explanation:
Remember that speed is equal to distance divided by time. Therefore, if you multiply time with speed, then you get the distance traveled.
So, we will do (7x+6) kph multiplied by (7x-6) hours to get 49x^2-36 km.
