Rate of change=R∆=(y2-y1)/(x2-x1)=∆y/∆x
(X1,Y1)(X2,Y2)
(1,2)(2,4)
R∆=∆y/∆x
=(4-2)/(2-1)
R∆=2
(2,4)(3,8)
R∆=(8-4)/(3-2)
R∆=4
(3,8)(4,16)
R∆=(16-8)/(4-3)
R∆=8
Answer:
<h2>$22.25</h2>
Step-by-step explanation:
Step one:
given data
we are told that the cost of one ride is $2.25
the entry fee= $6.5
the linear function for the situation is represented by the equation of line
y=mx+c
Step two:
let x be the number of ride
given that x=7
substituting we have
y=2.25(7)+6.5
y=15.75+6.5
y=22.25
In all Lupe we have to pay $22.25
I think it’s 1.8 because if you divide it and you get your answer if you were saying what goes in it

Answer:
(-3, 4)
Step-by-step explanation:
The midpoints of the diagonals of a parallelogram are coincident. This means the sums of coordinates at the ends of the diagonals are the same. For missing point P, we must have ...
P +(0, -3) = (-6, -6) +(3, 7)
P = (-6, -6) +(3, 7) -(0, -3)
P = (-6 +3 -0, -6 +7 -(-3))
P = (-3, 4)
Answer:
Plane speed = 40 m/s.
Wind speed = 300 m/s.
Step-by-step explanation:
Let the speed of the plane = Y
And the speed of the wind = X
If the plane then travel 340 miles per hour with the wind, that means the plane and the wind are moving in the same direction. Therefore,
X + Y = 340 ..... ( 1 )
Also, 260 miles per hour against the wind. That is, the plane is moving opposite to the direction of the wind. Therefore,
X - Y = 260 ..... ( 2 )
Solve the two equations simultaneously by addition. That will eliminate Y
X + Y = 340
X - Y = 260
2X = 600
X = 600/2
X = 300 m/s
Substitutes X in equation (1)
300 + Y = 340
Make Y the subject of formula by collecting the like terms
Y = 340 - 300
Y = 40 m/s
Therefore, the speed of the plane is 40 m/s. While the speed of the wind is 300 m/s.
