Find the missing factor BBB that makes the equality true. -35x^6=(-5x^2)(B)−35x 6 =(−5x 2 )(B)minus, 35, x, start superscript, 6

Sveta_85 [38]

Answer:

$B=7x^4$

Step-by-step explanation:

The given equality is

$-35x^6=(-5x^2)B$

Take the term $(-5x^2)$ to the left hand side. This means the term $-35x^6$ will be divided by $(-5x^2)$

$\dfrac{-35x^6}{(-5x^2)}=B$

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

$\dfrac{35x^6}{(5x^2)}=B$

Now $5\times 7=35$ and $x^{6-2}=x^4$

$7x^4=B$

So, the missing factor $B=7x^4$

Jasmine rides her bike 9 miles in 50 minutes. what is jasmines speed per hour

Firdavs [7]

<u>Given</u>:

Given that Jasmine rides her bike 9 miles in 50 minutes.

We need to determine the speed per hour.

<u>Time per hour:</u>

The time taken is 50 minutes. We need to convert minutes into hours.

Thus, we have;

$\frac{50}{60}=\frac{5}{6} \ hr$

Thus, the time taken to cover 9 miles is $\frac{5}{6} h r$

<u>Speed:</u>

The speed can be determined using the formula,

$Speed =\frac{Distance}{Time}$

Substituting the values, we have;

$Speed =\frac{9}{(\frac{5}{6})}$

Simplifying, we get;

$Speed =9 \times {\frac{6}{5}}$

$Speed =\frac{54}{5}$

$Speed = 10.8$

Thus, Jasmine's speed is 10.8 miles per hour.

What are the domain and range of the function Rx) = 4(x2 +6x2+5x-4)?

Snezhnost [94]

R(x) is a polynomial. Thus, the domain is the same as the range.

Domain = range = ALL REAL NUMBERS.

We can also express the answer as

(-infinity, infinity).
