Answer:
B. (10,4)
Step-by-step explanation:
Let x be the independent variable and y represents the dependent variable in the graph,
∵Graph represents the direct variation,
⇒ y ∝ x
⇒ y = kx
Where, k is the proportionality constant.
Here, k = 0.4,
⇒ Equation that shows in the graph would be,
y = 0.4x
At (4, 10),
10 = 0.4(4) ( False ),
⇒ (4, 10) is not in the graph.
At (10, 4),
4 = 0.4(10) ( True )
⇒ (10, 4) is on the graph.
At (0.04, 10),
10 = 0.4(0.04) ( false )
⇒ (0.04, 10) is not on the graph.
At (10, 0.04),
0.04 = 0.4(10) ( false )
⇒ (10, 0.04) is not on the graph.
Answer:
Ron is the faster walker ; Ron = 3mph | Stacie = 2.5mph
Step-by-step explanation:
To find per hour it is easy since both are factors of 60
(0.5*6)/(10*6) = 3mph
(0.25*10)/(6*10) = 2.5mph
B.
It says x = y + 3. So what they did was put y + 3 in the place of x.
Answer:
3:20 3/20 3.20
Step-by-step explanation:
X represents the length of a deck. There are three parts to this equations. The 1. width, 2. the length, and 3. the 5 feet shorter. Using the key words, y = the width of a deck (uses the term is which means =) So that takes the width part out of the equation. Then, 5 feet shorter means -5 than a number. That takes away the 5 feet shorter part of the equation. That leaves x to equal the length of the deck.
