Answer:

None of the equations are true for p = 3.4

Step-by-step explanation:

In order for the inequality to be valid we need to apply the value for p and check wether or not it is true. We gonna do for each of the following:

A. 3p < 10.2

3*3.4 < 10.2

10.2 < 10.2

Not true, since the left side is equal to the right side and not less.

B. 13.6 < 3.9p

13.6 < 3.9*3.4

13.6 < 13.26

Not true since 13.6 is greater than 13.26

C. 5p > 17.1

5*3.4 > 17.1

17 > 17.1

Not true since 17 is less than 17.1

D. 8.5 > 2.5p

8.5 > 2.5*3.4

8.5 > 8.5

Not true since the left side is equal to the right side.

State the domain of the following : a. y = √ x + 1 /√ 25 − x^2 b. f(x) = (√ 1 − x ) ln x

almond37 [142]

Answer:

a.) -1 < x < 5

b.) x <= 1

Step-by-step explanation: Domain is the independent variable (x).

For both question a and b, make sure that the number under the square root does not end up being negative. And the denominator of the fractional number is not equal to zero when variable x is being substituted for any value.

a.) y = √ x + 1 /√ 25 − x^2

Domain : -1 < x < 5

That is the minimum value for x is 0 and the maximum value is 4

b. f(x) = (√ 1 − x ) ln x

Domain : x <= 1

That is, x is less than or equal to 1

The maximum value for x is 1. x can be

1, 0, -1, -2, -3, ..........

I need this problem worked out. I already know the answer just not the work.

Answer

n = 30

Explanation

To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.

You 'remove' these numbers in backward PEMDAS.

So to 'remove' the 18, you subtract both sides by 18.

3-18 = -15

-n/2+18-18 = -n/2

So now you are left with -15 = -n/2.

To 'get rid' of the 2, you multiply each side by 2.

-15×2 = -30

-n/2×2 = -n

And now you have -30 = -n.

To 'get rid' of the negative sign, you multiply both sides by -1.

-30×-1 = 30

-n×-1 = n

So you get 30 = n or n = 30.

If you still have questions I'll answer them in the comments (under this question).

Write the equation of a line with a slope of 5 and a y-intercept of (0, 3). Write the equation in slope-intercept form.

lina2011 [118]

Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We are given that a line has a slope of 5, and a y intercept of (0,3)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.

Starting with the slope:

Substitute 5 as m into the equation

y=5x+b

Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3

Substitute 3 as b into the equation.

y=5x+3

Hope this helps!

Donal currently has 7,200 points in his fantasy baseball league, which is 20% more point than Scott how many points does scott h

Sati [7]

ANSWER:

Scott has 6000 points in his fantasy baseball league.

SOLUTION:

Given, Donal currently has 7,200 points in his fantasy baseball league.

It is 20% more points than Scott points.

We need to know how many points does scott have?

Let the points with scott be x.

Then, according to give information

Donal points = scott points + 20% of scott points

$\begin{array}{l}{7200=x+20 \% \times x} \\\\ {7200=x+\frac{20}{100} \times x} \\\\ {7200=x+\frac{1}{5} \times x} \\\\ {7200=x+\frac{x}{5}}\end{array}$
