What is the range of f(x) = ( 3/4)* - 4?


{yly>-4}
{yly> 3/4}
{yly<-4}
{yly< 3/4}

This is because of the rule that if we have rational coefficients, then one root of [tex]a+\sqrt{b}[/tex] must have a conjugate pair of [tex]a-\sqrt{b}[/tex]. Multiplying the conjugates will have the square roots cancel out.

Answer:

the correct answer is HLI

Answer:

x = 25

y = 6

Step-by-step explanation:

< B = < M

2x - 20 = 30

2x = 50

x = 25

AB = LM

7y - 8 = 2y + 22

5y = 30

y = 6

Answer:

Marcia is not correct.

See explanation below.

Step-by-step explanation:

The terms are

2x²

4xy

8xy^4

The terms broken down into products of prime factors are:

2x² = 2 × x × x

4xy = 2 × 2 × x × y

8xy^4 = 2 × 2 × 2 × x × y × y × y × y

To find the GCF, we circle the common factors of the three terms (here we use bold type instead of circling.)

2x² = 2 × x × x

4xy = 2 × 2 × x × y

8xy^4 = 2 × 2 × 2 × x × y × y × y × y

The GCF is the products of the circled (bold) factors.

GCF = 2x

Marcia's answer is the Least Common Multiple.

For the LCM, you use all factors that are common and not common with the larger exponent.

LCM = 2 × 2 × 2 × x × x × y × y × y × y = 8x²y^4

Marcia's mistake is that she calculated the LCM instead of the GCF.

Answer:

Marcia is not correct.

The explanation is above.

Answer:

See below.

Step-by-step explanation:

2x^2, 4xy, and 8xy^4

She is incorrect.

The GCF is 2x.

She found the greatest term, rather than the greatest factor.

Answer:

I don't see any answer options, but the total cost should be:

c = $5.00 + $1.25g

Step-by-step explanation:

Assuming that the cost is for one person playing g games, and that person needs to rent 1 pair of shoes, the cost should be:

c = $5.00 + $1.25g

Answer:

distance = 27x³ + 9x² - 3x , time = 3x ,

rate =?

[tex]distance = rate \times time \\ \\ rate = \frac{distance}{time} \\ \\ r = \frac{d}{t} \\ \\ r = \frac{27 {x}^{3} + 9 {x}^{2} - 3x}{3x} \\ \\ r = \frac{3x(9 {x}^{2} + 3x - 1) }{3x} \\ \\ r = 9 {x}^{2} + 3x - 1[/tex]

So; The rate of the car equal (9x²+3x-1)

Using the Fundamental Counting Theorem, it is found that there are 4,440 ways to assign the analysts.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

In this problem:

Hence:

N = (8 x 7 x 5 x 10) + (5 x 8 x 4 x 10) = 4400.

2:50 p.m.

Step-by-step explanation:

After he got home, his activities were:

homework: 45 minutes

break & snack: 35 minutes

baseball practice: 1 hour 55 minutes

1 hour = 60 minutes

Total time of activities:

45 minutes + 35 minutes + 60 minutes + 55 minutes = 195 minutes

195 minutes = 180 minutes + 15 minutes = 3 hours 15 minutes

Now we subtract 3 hours 15 minutes for 6:05 p.m.

   6:05

-   3:15

----------

We need to borrow 1 hour from 6 hours. 1 hour is 60 minutes. 6 hours becomes 5 hours. We add the 1 hour as 60 minutes to the 5 minutes.

Using the percentage concept, it is found that he keeps 21% of his mask collection on the wall.

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

[tex]P = \frac{a}{b} \times 100\%[/tex]

In this problem, the parameters are a = 63 and b = 300, hence the percentage is given by:

Answer:

If XYZ is a triangle, then Y = 8 cm

Step-by-step explanation:

X^2 + Y^2 = Z^2, by the Pythagorean Theorem.

Z, in this equation, represents the hypotenuse; the hypotenuse must be the longest side, and we can therefore eliminate C, 10 cm, without even beginning. Then, we may plug the given values in.

(6)^2 + Y^2 = 10^2

36 + Y^2 = 100

Y^2 = (100 - 36) = 64

Y = 8 cm

Answer:

4,767

Step-by-step explanation:

From the relationship between the distance and time, the rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the distance travelled by the bike after x minutes.

From the table:

Rate of change = (4480 - 1120) / (4 - 1) = 1120 ft/min

The rate of change is constant and represents a speed of 1120 ft/min. The cyclist rides her bike at a rate of 1120 ft/min.
