Answer:
10028.6 ft/hr
Step-by-step explanation:
speed = distance / time
234 Inches = 19.5 Feet
7 seconds = 0.00194444 hrs
so using the formula : 19.5 / 0.00194444 = 10028.6 ft/hr
(0,2)(-2,0)
slope = (0 - 2) / -2 - 0) = -2/-2 = 1
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
equation is : y = x + 2......solid line, means there is an equal sign....shaded below the line means less then....
ur inequality for this line is : y < = x + 2
(0,6)(3,0)
slope = (0 - 6) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(0,6)...x = 0 and y = 6
sub and find b, the y int
6 = -2(0) + b
6 = b
ur equation is : y = -2x + 6....dashed line means there is no equal sign...and shading below the line means less then...
so ur inequality of this line is : y < -2x + 6
In summary, ur 2 inequalities are : y < = x + 2 and y < -2x + 6
C. -5.4 -17.6+12.2= -5.4 because -17.6 goes first in the calculator but also its a negative
Answer:
and 
do not lie on the line
Step-by-step explanation:
Given
Required
Determine which points that are not on the line
First, we need to determine the slope (m) of the line:
Where
So;
Next, we determine the line equation using:
Where
becomes
To determine which point is on the line, we simply plug in the values of x to in the equation check.
For

Substitute 4 for x and 2 for y in
<em>This point is on the graph</em>
