Step-by-step explanation:      

<u>Step 1: Simplify</u>

<u />=-\frac{7}{2}z+4+\frac{1}{5}z-15<u />

<u>Step 2: Factor out common terms</u>

<u />=z\left(-\frac{7}{2}+\frac{1}{5}\right)+4-1<u />

<u>Step 3: Simplify</u>

<u />=-\frac{33}{10}z+4-15<u />

<u>Step 4: Subtract the numbers 4 - 15 = -11</u>

<u />=-\frac{33}{10}z-11<u />

<u>Step 5: Simplify</u>

<u />=-\frac{33z}{10}-11<u />

 

Explanation in words:        

- To solve this equation, the first step is to simplify the equation.

- To solve this equation, the second step is to factor out the common terms in this equation

- To solve this equation, the third step is to simplify the equation from step two.

- To solve this equation, the fourth step is to subtract the numbers 4 - 15 = -11

- To solve this equation, the fifth step is to simplify the equation from step four.

 

Answer:      

=-\frac{33z}{10}-11  

Hope this helps.

Step-by-step explanation:

(-\frac{7}{2} z +4)+(\frac{1}{5} z -15)\\\\=-\frac{35}{10} z+4+\frac{2}{10}z -15\\\\=-\frac{33}{10}z -11

Can someone help me please
Ostrovityanka [42]

Answer:

D

Step-by-step explanation:

as we can easily see, the x-coordinates of all points increased by 7.

so, we need a solution with "x+7". that eliminates B and C.

with that transition (glide) the triangle moved to the right into the 4th quadrant.

and now, as a second step, it needs to move up, above the x-axis, into the 1st quadrant.

and that is a reflection across the x-axis.

a reflection across the y axis would bring it back into the 3rd quadrant, where it started.

so, it is D.

Consider the given density curve.
alisha [4.7K]

The Median of the density is -6.

An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

It is clearly visible from the uniform density curve given in the question that the median of the population density is  -6.
Because the area to the left and right of the density curve is the same.

Hence, the Median of density is -6.

In ΔNOP, the measure of ∠P=90°, PO = 77, NP = 36, and ON = 85. What ratio represents the cosine of ∠N?
Usimov [2.4K]

Answer:

36:85

Step-by-step explanation:

Given the right angled triangle as shown in the attachment, the cos of angle N can be gotten by simply using the CAH method in SOH CAH TOA.

According to CAH

Cos∠N = Adjacent/Hypotenuse

Hypotenuse is the longest of the triangle |ON| = 85

Since the opposite side to ∠N is 77, the third side will be the Adjacent side.

Adjacent side will be |NP| = 36

Therefore:

Cos∠N = 36/85

The ratio that represents the cosine of ∠N is 36:85

Please just give me the actual answer to this question Or at least help me understand because I don't get it and I have looked i
iren [92.7K]

Step-by-step explanation:

To begin with, this is an English question.

Here is what ethos, pathos and logos mean:

Ethos: writing an ethos response requires an argument that includes trustworthy language.

Pathos: writing a pathos response requires an argument that includes emotion and make the reader use their feelings while reading the piece.

Logos: writing a logos response requires an argument that includes facts and logic to ensure the reader that what you are saying is true and reasonable.

In this task, you must use ethos, pathos, and logos separately and try to convince your parents to stay home by yourself.

example:

Logos: Staying home by myself can teach me great responsibility and prepare me for the future. It is much better for me to learn how to take care of myself and what to do in case of an emergency. It is a great opportunity to practice independency. My grandparents would probably rather be undisturbed and I don't wish to trouble them. I am getting older and need to learn how to take care of everything alone. I think I can handle it and is good training. Furthermore, it is a good chance to have some alone time as it is shown that being alone can be healthier for individuals. To sum up, staying home alone is a responsibility I need to practice and I am ready for it.

I hope that helped

What is the equation of the line that passes through the point (-2,7) and has a slope of zero​
Lina20 [59]

Answer:

Equation of the line that passes through the point (-2,7) and has a slope of zero​ is given as

y=7

Step-by-step explanation:

Equation of line is given as

y-y_1=m(x-x_1)   -----------(1)

Here

m=0 \ \ \ and \ \ \ (x_1, y_1) = (-2, 7)

Substituting values in equation (1)

y-7=0(x+2)\\y=7
