Explain whether the points (−3,8), (−2,3), (−1,−2), (0,−7), (1,−12), and (2,−17) represent the set of all the solutions for the
Volgvan
Answer:
D
Step-by-step explanation:
We simply put each of the points to test
For a point to be correct, if we substitute the x-coordinate value, we should get the value of the y-coordinate
So let’s proceed
(-3,8)
8 = -5(-3) - 7
8 = 15 -7
8 = 8
(-2,3)
3 = -5(-2) - 7
3 = 10 -7
3 = 3
(-1,-2)
-2 = -5(-1) - 7
-2 = 5-7
-2 = -2
(0,-7)
y = -5x -7
y = -5(0) - 7
y = 0-7 = -7
(1,-12)
y = -5(1) -7
-12 = -5 -7
-12 = -12
(2,-17)
-17 = -5(2) -7
-17 = -10-7
-17 = -17
We can see that all the listed points are on the given line
Although all these points lie on the line, we cannot say they represent the set of all solutions
The set of all solutions can simply be represented by the line of the equation
Hey there! :D
Just plug in the values of x.
y= 1/2(-5)-2
y= -2.5-2
y=-4.5
First point: (-5, -4.5)
y= 1/2(-2)-2
y=-1-2
y=-3
Second point: (-2, -3)
y= 1/2(1)-2
y =.5-2
y=-1.5
Third point: (1,-1.5)
y= 1/2(3)-2
y= 1.5-2
y=-.5
Fourth point: (3, -0.5)
y= 1/2(6)-2
y=3-2
y=1
Fifth point: (6,1)
I hope this helps!

66° 44 and 70 make 114. 180 minus 114 makes 66
Answer:
Step-by-step explanation:
The function is
Where
x = Time in hours
y = Velocity in kilometers per hour
Here y = 30 km/hr
The particle will reach 30 km/hr after .
