Answer:

A - 108 strips

Step-by-step explanation:

1 yard = 36 inches

3 yards = 108 inches.

If Sara cuts 1-inch strips, she will have 108 strips in total.

Hope this helps!

Answer:

A 108 strips

Step-by-step explanation:

1 yd = 3 ft

3 ft = 3 * 12 inches = 36 inches

3 yds = 3 * 36 = 108

If each strip is 1 inch, we can cut 108 1 inch strips

Answer:

Part A) The equation in standard form is $75x-y=60$

Part B) The equation in function notation is $f(x)=75x+60$

Part C) The graph in the attached figure

Step-by-step explanation:

Part A)

Let

x -----> the number of days

y ----> the total rent hat Maria has to pay for renting the coat

we have

(3,285) and (6,510)

Find the slope of the linear equation

$m=(510-285)/(6-3)=75\frac{\$}{day}$

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

we have

$m=75$

$(x1,y1)=(3,285)$

substitute

$y-285=75(x-3)$ ----> equation of the line into slope point form

Find the equation of the line into slope intercept form

$y=mx+b$

$y=75x-225+285$

$y=75x+60$ ----> equation of the line into slope intercept form

Find the equation of the line into standard form

$Ax+By=C$

$y=75x+60$

$75x-y=60$ -----> equation of the line into standard form

Part B) Write the equation obtained in Part A using function notation.

we have

$y=75x+60$

Convert to function notation

Let

f(x)=y

substitute

$f(x)=75x+60$ ---> equation in function notation

Part C) Describe the steps to graph the equation obtained above on the coordinate axes

To graph the linear equation find out the intercepts

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=75(0)+60=60$

The y-intercept is the point (0,60)

Find the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$0=75x+60$

$x=-60/75=-0.8$

The x-intercept is the point (-0.8,0)

To graph the line plot the intercepts ad join the points

see the attached figure
