Answer:
(x) = 1/2x-3/2
Step-by-step explanation:
The inverse is the opposite of the equation given in this case is 2x+3 and the inverse is when you switch the x and the y and you solve for y.
You would write it 2=10(20+2)
Answer:
D
Step-by-step explanation:
The basic equation to solve this would be D = RT, which is
D is Distance
R is Rate (speed)
T is time
To find total distance D, we can find individual distances for two legs of the whole.
First Leg:
R = 8
T = a
D = 8a
Second Leg:
R = 7.5
T = b
D = 7.5b
Total distance D is:
D = 8a + 7.5b
Moreover, we know student runs 45 minutes in total hence a + b = 45 or we can say a = 45 - b, so we can replace this in the equation found:
D = 8a + 7.5b
D = 8(45 - b) + 7.5b
Answer choice D is right.
Answer:
Yes
Step-by-step explanation:
Given that there is ¹/12 foot in 1 inch, this can be interpreted as being the constant of proportionality for the relationship between feet and inches. This means, for the graph to be said to represent this relationship, the constant of proportionality, which is y/x must be ¹/12.
How do we know this? Check this out using the four points given on the graph.
(12, 1) => y/x = ¹/12
(24, 2) => y/x = ²/24 = ¹/12
(36, 3) => y/x = ³/36 = ¹/12
(48, 4) => y/x = ⁴/48 = ¹/12
As we can see, the graph represents the shows a relationship between feet and inches.
<h2>y = 1x + 2</h2><h2>or</h2><h2>y = x + 2</h2><h2 /><h3>1x is the slope and +2 is the y-intercept</h3>
