PLEA HELP ME WORTH ALOT OF POINTS
Harlamova29_29 [7]
<h2>Answer:</h2>

  • option (c) = -19 + x = -21

<h2>Step by step explanation:</h2>

<u>Question</u> : A number added to -19 is -21

<h3><u>Solution</u> ↓</h3>

First of all to make equation

Equation means LHS = RHS

For eg we take :-

50 - 20 = 10 + 20

30 = 30

Therefore, LHS = RHS

<h3>According to the question :</h3>

  • Which number would we add in -19 to get -21 and we get LHS = RHS

Make an equation

-19 + x = -21

x = -21 + 19

x = -2

Add -2 in the variable of x

Variable means any unknown value we used in maths. For eg :- x,y,z,a,b,c,p,q,r etc.

-19 + (-2) = -21

-19 - 2 = -21

-21 = -21

Therefore, LHS = RHS.

A person riding in a elevator travels 240 feet in 30 seconds. What equation represents this relationship? How many feet will the
frosja888 [35]
The answer to this question is letter C

We can approach this by first finding the rate of feet per second traveled.

240(feet)/30(seconds)= 8 feet per second.

This answer resembles the slope for answer choice C.

To find the distance traveled in 10 seconds we do 10*8= 80 feet.

I hope this helps, please like and brainliest if correct, thank you!

Someone please explain the differentiation product rule. It'd be great if you can use the example question given below.
Vikentia [17]

Answer:

The product rule is if the two "parts" of the function are being multiplied together, and the chain rule is if they are being composed. For instance, to find the derivative of f(x) = x² sin(x), you use the product rule, and to find the derivative of g(x) = sin(x²) you use the chain rule.

(sorry i didn't use the example but i hope this sort of helps!)
