Answer:
(5,19) lies on the graph of the transformed function y = f(1/5x)
Step-by-step explanation:
Suppose (1,19) is on the graph of y = f (x)
the graph of the transformed function y = f(1/5x)
1/5 is multiplied with x in f(x)
1/5 is less than 1 so there will be a horizontal stretch in the graph by the factor of 1/5
To make horizontal stretch we change the point
f(x)=f(bx) then (x,y) --->( x/b,y)
We divide the x coordinate by the fraction 1/5
(1,19) ----> 
So (5,19) lies on the graph of the transformed function y = f(1/5x)
Answer:
B. y ≤ –3x + 5
Step-by-step explanation:
Its B, all y-values are less than -3x+5. also consider root by setting -3x+5=0
x=5/3 is positive so its the second one

Answer:
Step-by-step explanation:
we know that
The solution of the inequality is the shaded area below the solid line (the gray area)
The slope of the solid line is negative
The y-intercept of the solid line is positive
The equation of the solid line is equal to
therefore
the equation of the inequality is equal to
Answer:
c
Step-by-step explanation: not much has change the perminater will always stay the same
So,
The length is always 1.5 times the width.
l = 1.5w
lw = 24
lw = 54
lw = 96
Or, we could put it this way:
1.5w(w) = 24
1.5w(w) = 54
1.5w(w) = 96
So,
1.5w^2=24
1.5w^2=54
1.5w^2=96
Dividing both sides by 1.5, we get:
w^2 = 16
w^2 = 36
w^2 = 64
And solving for the only logical dimension, we get:
w = 4
w = 6
w = 8
And their corresponding lengths:
l = 1.5(4) = 6
l = 1.5(6) = 9
l = 1.5(8) = 12
So a few lengths could be:
(l,w)
(6,4)
(9,6)
(12,8)
Of course, there are infinite solutions.
