Rx + sx/t = 1 solve for x

2 answers:

4 0

(rx + sx) / t = 1....multiply both sides by t
rx + sx = t...factor the left side
x(r + s) = t ...divide both sides by (r + s)
x = t / (r + s) <===

abx - cdx = 15m...factor left side
x(ab - cd) = 15m...divide both sides by (ab - cd)
x = (15m) / (ab - cd) <====

Thanks for your question!

First thing we have to do here is take t to the other side by multiplication:

rx + sx = t

Now, group together, x as the GCF:

x(r+s) = t

Now, divide

x = t/(r+s)

Hope this helps!

Select the correct answer. which equation could possibly represent the graphed function?

MakcuM [25]

The function for the given graph is f(x) = (x - 4)(x + 2)(x + 4).

<h3>How to represent a graph by an equation?</h3>

A graph can be represented by the equation y = f(x).
In the equation, the variable x is called the independent variable and the variable y is called the dependent variable.

<h3>Calculation:</h3>

In the given graph,

The points that lie on the x-axis are (-4, 0), (-2, 0), and (4, 0) where y-coordinate is 0 and the x coordinates are -4, -2, and 4.

On solving the given functions,

Option A:

f(x) = (x - 4)(x + 2)(x + 4)

Since y = 0 consider f(x) becomes 0

So,

(x - 4)(x + 2)(x + 4) = 0

According to the zero product rule,

x - 4 = 0, x + 2 = 0, and x + 4 = 0

⇒ x = 4, x = -2 and x = -4.

Thus, option A represents the function of the given graph.

I need help this question?

Masja [62]

Answer:

Correct answer: F. graph F or x ∈ |-5 ; 5| (including endpoints)

Step-by-step explanation:

Let us first define the absolute value:

| x | = 1. { x with condition x ≥ 0 }

or 2. { - x with condition x < 0 }

This is a linear inequality

1. x ≤ 5 ∧ x ≥ 0 ⇒ 0 ≤ x ≤ 5 or interval x ∈ |0 ; 5| (including endpoints)

2. - x ≤ 5 when we multiply both sides of the equation by -1 we get:

x ≥ -5 ∧ x < 0 ⇒ -5 ≤ x < 0 or interval x ∈ |-5 ; 0) (including -5)

The solution to this linear inequality is the union of these two intervals:

x ∈ |-5 ; 0) ∪ |0 ; 5| ⇒ x ∈ |-5 ; 5| (including endpoints)

x ∈ |-5 ; 5| (including endpoints)

God is with you!!!

If sin theta equals 12 divided by 13 and theta is in quadrant 2 cos20 equals? and cos theta equals?

Anni [7]

Answers:

cos(2theta) = -119/169
cos(theta) = -5/13

=====================================================

The given info is:

sin(theta) = 12/13
theta is in quadrant II

From that, we can use the pythagorean trig identity to find that cos(theta) = -5/13. Keep in mind that cosine is negative in quadrant II.

Now use the trig identity below to compute cos(2theta)

$\cos(2\theta) = \cos^2(\theta)-\sin^2(\theta)\\\\\cos(2\theta) = \left(\frac{-5}{13}\right)^2-\left(\frac{12}{13}\right)^2\\\\\cos(2\theta) = \frac{25}{169}-\frac{144}{169}\\\\\cos(2\theta) = \frac{25-144}{169}\\\\\cos(2\theta) = -\frac{119}{169}\\\\$

Other options you could use are these identities

$\cos(2\theta) = 2\cos^2(\theta)-1\\\\$

$\cos(2\theta) = 1-2\sin^2(\theta)\\\\$
