Answer:
-3 is the answer.
Step-by-step explanation:
Answer: Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Answer:
x = 6 lb
Step-by-step explanation:
Let
Total weight of the candy = x
3/20x + 1.2 lb + 3/5x + 0.3 lb = x
3/20x + 3/5x + 1.5 lb = x
3x+12x/20 + 1.5 lb = x
15/20x + 1.5 = x
1.5 = x - 15/20x
1.5 =20x -15x /20
1.5 = 5/20x
1.5 = 1/4x
x = 1.5 ÷ 1/4
= 1.5 × 4/1
= 6
x = 6 lb
Answer: Yes; " d/t = r " ;
__________________________
is, in fact, an equivalent equation to: "d = r t" .
___________________________
Explanation:
___________________________
Consider the equation: "d = rt" (which is, " d = r*t ").
We are asked if: " d/t = r " an "equivalent equation" [ to: " d = rt "] .
___________________________
Note that: "d/t = r " is the same as: ↔ "r = d/t ".
So, given: "d = rt" ; let us rewrite the equation, by isolating: "r" on one side of the equation:
_____________________
→ d = r t ; divide EACH SIDE of the equation by "t" ; to isolate "r" on one side of the equation:
__________________________
→ d/t = (r*t) / t ; to get:
→ d/t = r ; so yes; "d/t = r" and: "d = rt" are equivalent equations.
___________________________
Note: In practice, these variables are often used in the formula:
"d = rt" ; or, "distance = rate * time" .
