Answer:

It will cost $36.38 to travel 8.9 miles.

Step-by-step explanation:

In order to get how much it will cost to travel 8.9 miles, you need to first set up a linear equation (in slope-intercept form, which is y=mx+b ). You can do this with what the problem has given us. Since there's a flat fee of $3, that is the y-intercept or the b slope-intercept form. Then there is $3.75 added for every additional mile traveled, making it the slope or the m in slope-intercept form. That makes the equation look like:

y=3.75x+3

The x in that equation represents how far you traveled. Therefore in order to find out 8.9 miles, plug in 8.9 for x.

y=3.75(8.9)+3

Simply solve the equation and you will have how much it will cost to travel 8.9 miles.

y=33.375+3

Now add the like terms:

y=36.375

Since it needs to be rounded to the nearest cent, you will round to the nearest tenth:

y=36.38

Therefore, it will cost $36.38 to travel 8.9 miles.

What is the slope and y-intercept of the linear equation y = 5x - 4?<br> m2 =<br> ь
Ksju [112]

Answer:

Where m is the slope and b is the y-intercept. So in this case m=5 and b=-4, or in other words the slope is 5 and the y-intercept is (0,-4) (since x=0 for all y-intercepts).

Which polynomial is a perfect square trinomial?
Levart [38]

Answer:

\large\boxed{16x^2-24x+9=(4x-3)^2}

Step-by-step explanation:

\text{Perfect square:}\ (a-b)^2=a^2-2ab+b^2\\=======================\\\\25x^2-20x-16\to\text{NOT. Because is}\ -16=-4^2\\\\9a^2-30a-25\to\text{NOT. Because is}\ -25=-5^2\\\\25b^2-15b+9=(5b)^2-2(5b)\left(\dfrac{3}{2}\right)+3^2\to\text{NOT. Because is}\ b=\dfrac{3}{2}\ \text{and}\ b^2=3^2\\\\16x^2-24x+9=(4x)^2-2(4x)(3)+3^2=(4x-3)^2\ \boxed{YES\ :)}
