Domain is the x value. So you would just plug in every value in the domain set into the f(x) function.
5 (-2) + 4 =
-6
5 (3) + 4 =
19
5 (5) + 4 =
29
Your answer is B.
Well first we need to focus on the first rope. So that is 2000 inches long now we need to subtract 264 from that which is 1738. Now the second rope is 2,681 inches so we will subtract 2,681 - 1738 to see which is longer 2,681 - 1738 = 943!
So your answer is 943
Answer:
<u>(-3, -10)</u>
Step-by-step explanation:
We are asked to solve the system of equations simultaneously.
We need to equate the equations.
=============================================================
Solving :
⇒ -4 + 2x = 4x + 2
⇒ 4x - 2x = -4 - 2
⇒ 2x = -6
⇒ x = -3
============================================================
Finding y :
⇒ y = 4(-3) + 2
⇒ y = -12 + 2
⇒ y = -10
============================================================
Hence, the solution :
<u>(-3, -10)</u>
Assume that the cost of the milk is x.
We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:
cost of sandwich = cost of milk + 0.75
cost of sandwich = x + 0.75
Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.
We will transform this into an equation as follows:
total cost = cost of 4 sandwiches + cost of 4 containers of milk
7 = 4(x+0.75) + 4(x)
Solve the above equation to get x as follows:
7 = 4x + 3 + 4x
7-3 = 8x
8x = 4
x = 0.5
Therefore:
cost of milk = x = $0.5
cost of sandwich = x+0.75 = 0.5+0.75 = $1.25
