Ummm ok. for informing us

Answer:

the image is given below

step-by-step explanation:

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the speed is [tex]135[/tex]miles per hour > is false

step-by-step explanation:

we know that

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

[tex]y/x=k[/tex]

for the point [tex](1.5,90)[/tex]

substitute the values of x and y

[tex]k=90/1.5=60\ miles/hour[/tex]

the linear equation is equal to

[tex]y=60x[/tex]

statements

case a) it takes [tex]2[/tex] hours to go [tex]120[/tex]miles

the statement is true

because

substitute

for [tex]x=2[/tex]

find the value of y in the linear equation

[tex]y=60(2)=120\ miles[/tex] > is correct

case b) the speed is [tex]135[/tex]miles per hour

the statement is false

because the speed is [tex]60\ miles/hour[/tex]

case c) the unit rate for the trip is [tex]60\ miles/hour[/tex]

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took [tex]20[/tex] minutes to go the first [tex]20[/tex]miles

the statement is true

because

substitute

for [tex]x=20\ minutes=(1/3)\ hour[/tex]

find the value of y in the linear equation

[tex]y=60(1/3)=20\ miles[/tex] > is correct

What's the denominator
