Answer:
Step-by-step explanation:
Domain is the set of all possible inputs (x) for the function f(x)
The range is the set of all possible values for that domain
This function is 4x + y = 3 which can be re-written as y = 3-4x
Plug in each of the domain values and you will get the range
For -2 : y = 3-4(-2) = 3 + 8 = 11
For 1: y = 3-4(1) = -1
For 5: y = 3-4(5) = -17
So range is {-17, -1, 11}
0.75 x 500 is 375 of gold in 500 kg of ore
Remember

so
notice that 200=2*2*2*5*5, so x cannot be a whole number
take the log base 10 of both sides


divide both sides by


if we used

instead of

we would get

because
Answer:
cost of large delivery truck = $60,000
cost of small delivery truck = $45,000
Step-by-step explanation:
let,
the cost of large delivery truck = 'x'
the cost of small delivery truck = 'y'
Now, according to the question,
3x + 2y = 270000
4x + 3y = 375000
By solving the above 2 equation , we get;
x = 60000
y = 45000
Perpendicular slopes multiply to -1, so are <em>negative reciprocals.</em>
-1 / -3 = 1/3
Answer: B. 1/3
