Given the following information, write the equation of the line in slope-intercept form. Slope = -8 and y-intercept = 4

Montano1993 [528]

Answer:

y = -8x + 4

Step-by-step explanation:

Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.

In this case, the slope is -8 and the y-int is 4 so we naturally plug those in

Find f'(x) if f(x)=3squareroot(x+2)<br>using the definition of the derivative!

ycow [4]

I hope this helps you

f (x)=(x+2)^3/2

f'(x)=3/2. (x+2)^3/2-1

f'(x)=3/2 (x+2)^1/2

f'(x)=3/2.square root of (x+2)

Zepler [3.9K]

Answer:

$6 * (3 - 1) + 5 \div 1 = 17$

Step-by-step explanation:

Given

$6\ [\ ]\ (\ 3\ [\ ]\ 1\ )\ [\ ]\ 5\ [\ ]\ 1\ =\ 17$

Required

Fill in the box with +,-, x, and ⌯ (once each)

This question is solved using trial by error approach.

After some tests, the solution that matches the equation is:

$6 * (3 - 1) + 5 \div 1 = 17$

A carpenter is assigned the job of expanding a rectangular deck where the width is one-fourth the length. The length of the deck

leva [86]

Let the width be W, then the length is 4W (since the width is 1/4 the length)

The area of the original deck is $W*4W=4W^{2}$

The dimensions of the new deck are :

length = 4W+6
width=W+2

so the area of the new deck is :

$(4W+6)(W+2)= 4W^{2}+8W+6W+12= 4W^{2}+14W+12$

"<span>the area of the new rectangular deck is 68 ft2 larger than the area of the original deck</span>" means that we write the equation:

$4W^{2}+14W+12=68+4W^{2}$

$14W+12=68$

$14W=68-12=56$

$W= \frac{56}{14}= 4$

the length is $4W=4*4=16$ ft

Answer: width: 4, length: 16
