Answer:
23.25 MPH
Step-by-step explanation:
7 3/4 x 3 = 23.25
1/3 x 3 = 3/3 = 1
So for 1 hour she will ride 23.25 MPH :D
Answer:
The value of x = -6
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that g(x) = 2 x + 4 and g (x ) = -8
⇒ Equating
2 x +4 = - 8
Subtracting '4' on both sides, we get
2 x + 4 - 4 = -8 -4
⇒ 2 x + 0 = -12
⇒ 2 x = -12
<u><em>Step(ii):-</em></u>
Dividing '2' on both sides, we get
x = -6
The value of x = -6
Let x be the time in hours and y be the distance driven in miles. If x = 0, then no time has passed which means he can't drive anywhere. So y = 0 when x = 0. The first point is (0,0). Note: the y intercept is 0 as this is where the graph crosses the vertical y axis.
One hour later, he has driven 35 miles because 140/4 = 35. In other words, his speed is 35 miles per hour (mph). So we have the second point (x,y) = (1,35). Note: the rate of change is the same as the slope in this problem. Also the rate of change is the same as saying "speed" for this problem.
Plot the two points (0,0) and (1,35) and draw a straight line through the two points. Extend the line as far as you can. The graph is linear assuming he maintains his speed to be the the same throughout the whole trip.
Answer:
(1, 4) and (1,3), because they have the same x-value
Step-by-step explanation:
For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.
In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.
Therefore, the relation is not a function anymore if both ordered pairs are included.
<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
