Graph 14x+34y=1 pretty please with a cherry on top!Also thank-you

Mathematics

Svetlanka [38]3 years ago

To make it much easier, it should be converted to the slope-intercept form
 y = mx + b

To do so, 14x + 34y = 1 turns to:
34y = -14x + 1

Divide both sides by 34:
\frac{34y}{34} =  \frac{-14}{34} x +  \frac{1}{34}
Simplified:
y = \frac{-7}{17} x + \frac{1}{34}

Answer: y = -\frac{7}{17} x + \frac{1}{34}
Here is the graph:

Mariana [72]
<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?
-----
n = [z*s/E]^2
---

n = [2.17*18/4]^2 = 96 when rounded up

A ladder 25 feet long is leaning againstthe wall of a house. The base of the ladder ispulled away from the wall at a rate of 2 f
WITCHER [35]

Answer: a) -7/12 ft/s, -20 ft/s, -7 ft/s

              b) 527/24 Ft²/s

              c) 2/25 rad/sec

Step-by-step explanation:

a) b=7 ; a^2+b^2 = 25^2

             a^2+b^2 = 625

Differentiate w.r.t = 2a (da/dt) + 2b ( db/dt) = 0

                                    b(db/dt) = -a(da/dt)

As found from above put a=24 b=7,15 and 24. You will get the reuqired answer.

b) Area of the triangle = 1/2 * b*h

differentiate wrt to time leads to the following relation:

2dA/dt= h(db/dt)+b(dh/dt) \\dA/dt=24-49/24 = 527/24 Ft^2/sec

c) sin (Θ) = b/25

differentiate it again to give

cos(0.284)(d\theta/dt) =  (1/25) (db/dt) \\=2/25 rad/sec

Sketch a graph of the function. Given the piecewise definition f(x) ={- 2x - 4 if x &lt; - 2 f (x)= {x+3 if x&gt;-2 Domain: Rang
kakasveta [241]

Explanation:

f(x)=\begin{cases}-2x-4\text{    if x -2}\end{cases}

The line of the first part of the function, without the restriction of x <=-2:

The line of the second part of the function, without the restriction is:

To graph the full function, we have to draw a line over the green dashed line until x = -2 and then continue drawing but now over the orange dashed line

Answer:

The graph of the function is:

• Domain:

\begin{gathered} (-\infty,\infty) \\ \text{ or also} \\ -\infty• Range[tex]\begin{gathered} \lbrack0,\infty) \\ \text{ or also} \\ 0\le y

Find the value of x and y. (geometry)
saveliy_v [14]
Ok so the value of x is 6 those lines on the 6 and x lines means that they are congruent. Then to figure out y you would use Pythagorean theorem 6^2+6^2
36+36=72
Square root 72 is about 8.5
8.5 would be y. Let me know if this is right and if this helps
