Answer:

Step-by-step explanation:

16) 4 * y/5

The value of y should be greater than 5

For example if y = 6, then 4* 6/5 = 24/5 = 4.8

If y= 10, then 4* 10/5 = 4 * 2 = 8

y > 5

17) 1 pound = 16 ounce

3020 pounds =3020 * 16 = 48320 ounces

What’s the derivative of x^2 - 3

geniusboy [140]

Answer:

$\displaystyle \frac{dy}{dx} = 2x$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Derivative Property [Addition/Subtraction]: $\displaystyle \frac{d}{dx}[f(x) + g(x)] = \frac{d}{dx}[f(x)] + \frac{d}{dx}[g(x)]$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle y = x^2 - 3$

Step 2: Differentiate

Derivative Property [Addition/Subtraction]: $\displaystyle y' = \frac{d}{dx}[x^2] - \frac{d}{dx}[3]$
Basic Power Rule: $\displaystyle y' = 2x$

Please help asap question five*

AysviL [449]

Answer:

slope = - 3 y-intercept = 36

Step-by-step explanation:

12x + 4y = 144 , will allow this to be done.

so 4y = - 12x + 144

now dividing both sides of the equation by 4 will give

y = - 3x + 36 , which is now in the required form

slope = - 3 and y-intercept = 36

jok3333 [9.3K]

Answer:

Option D) c = 100, a = 50, s = 20

Step-by-step explanation:

we have

6c + 7a + 2s = 990 -----> equation A

3c + 3a + 4s = 430 -----> equation B

2c + 4a + 4s = 480 ----> equation C

Isolate variable s in equation A

2s = 990 -6c-7a

s=495-3c-3.5a -----> equation D

Substitute equation D in equation B and in equation C

3c + 3a + 4(495-3c-3.5a) = 430

3c + 3a +1,980-12c-14a= 430

-9c-11a=-1,550 -----> equation E

2c + 4a + 4(495-3c-3.5a) = 480

2c+4a+1,980-12c-14a=480

-10c-10a=-1,500 -----> 10c+10a=1,500 -----> equation F

Solve the system of equations E and F by graphing

using a graphing tool

Let

The variable c -----> the x-axis

The variable a ----> the y-axis

The solution is the point (50,100)

see the attached figure

c=50, a=100

Find the value of s

s=495-3(50)-3.5(100)=-5 -----> is not make sense

therefore

Let

The variable c -----> the y-axis

The variable a ----> the x-axis

The solution is the point (50,100)

a=50, c=100

Find the value of s

s=495-3(100)-3.5(50)=20

therefore

The solution is

c=100,a=50,s=20

Find the equation of the line graphed below. Write the equation in the form y = mx + b and identify m and b m = b =

Alla [95]

ANSWER:

m = -3/4

b = -3

$y=-\frac{3}{4}x-3$

STEP-BY-STEP EXPLANATION:

We have that the equation in its slope-intercept form is the following:

$\begin{gathered} y=mx+b \\ \text{where m is the slope and b is y-intercept} \end{gathered}$

We calculate the slope as follows:

$m=\frac{y_2-y_1}{x_2-x_1}$

To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:

$m=\frac{-3-0}{0-(-4)}=\frac{-3}{4}=-\frac{3}{4}$

Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:

$y=-\frac{3}{4}x-3$
