Answer:

yes

Step-by-step explanation:

There are several ways to go at this.

My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.

Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.

(((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0

The value of h(5) is zero, so x-5 is a factor of h(x).

In a fish tank 8/11 of the fish have red a stripe on them. If 16 of the fish have red stripes how many total fish are in the tan

Nataly_w [17]

X - the number of fish

8/11 of the fish have a red stripe.
16 of the fish have a red stripe.

$\frac{8}{11}x=16 \\
x=16 \times \frac{11}{8} \\
x=2 \times 11 \\
x=22$

There are 22 fish in the tank.

On the coordinate grid, the graph of y= 3/x-1+3 is shown. it is a translation of y =3/x

crimeas [40]

Answer:

1 unit right and 3 units up

Step-by-step explanation:

The graph of the given function has equation

$f : y = \frac{3}{x - 1} + 3$

This is obtained after translating the graph of

$g : y = \frac{3}{x}$

We can rewrite f in terms g to obtain:

$f(x) = g(x - 1) + 3$

This is a shift to the right by 1 unit and and a shift up by 3 units.

Therefore

$y = \frac{3}{x - 1} + 3$

is a translation of

$y = \frac{3}{x}$

1 unit right and 3 units up

If Mary traveled 200 miles on foot, then traveled 200 miles on bike then traveled 200 miles by car how long did it take her to g

Serjik [45]

Step-by-step explanation:

Distance word problems are a common type of algebra word problems. They involve a scenario in which you need to figure out how fast, how far, or how long one or more objects have traveled. These are often called train problems because one of the most famous types of distance problems involves finding out when two trains heading toward each other cross paths.

In this lesson, you'll learn how to solve train problems and a few other common types of distance problems. But first, let's look at some basic principles that apply to any distance problem.

The basics of distance problems

There are three basic aspects to movement and travel: distance, rate, and time. To understand the difference among these, think about the last time you drove somewhere.

The distance is how far you traveled. The rate is how fast you traveled. The time is how long the trip took.

The relationship among these things can be described by this formula:

distance = rate x time

d = rt

In other words, the distance you drove is equal to the rate at which you drove times the amount of time you drove. For an example of how this would work in real life, just imagine your last trip was like this:

You drove 25 miles—that's the distance.

You drove an average of 50 mph—that's the rate.

The drive took you 30 minutes, or 0.5 hours—that's the time.

According to the formula, if we multiply the rate and time, the product should be our distance.

And it is! We drove 50 mph for 0.5 hours—and 50 ⋅ 0.5 equals 25, which is our distance.

What if we drove 60 mph instead of 50? How far could we drive in 30 minutes? We could use the same formula to figure this out.

60 ⋅ 0.5 is 30, so our distance would be 30 miles.

Solving distance problems

When you solve any distance problem, you'll have to do what we just did—use the formula to find distance, rate, or time. Let's try another simple problem.

1 meter is equivalent to 100 centimeters. Kemp is 193 centimeters tall. Trey is 1.9 meters tall. Who is taller, Kemp or Trey?
