2x+4y=16 what is the slope intercept form

1 answer:

3 0

Since slope intercept is y=mx+b, you first want to get rid of the 2x by subtracting it from both sides. after, you should end up with 4y=16-2x or 4y=-2x+16, they both are the same, but some teachers might prefer the slope first. after that, you want to get the y alone, so you divide everything by 4. you should end up with the slope intercept form being y=-2/4x+4, simplified to y=-1/2x+4.

HELP ASAP PLZ &THANK YOU :)

The standard form:

$Ax+By=C$

The slope-intercept form:

$y=mx+b$

m - slope

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

b - y-intercept (0, b).

We have the point (0, 43) → b= 43.

Next point (2, 55). Substitute to the slope formula:

$m=\dfrac{55-43}{2-0}=\dfrac{12}{2}=6$

Therefore we have:

$y=6x+43$ <em>subtract 6x from both sides</em>

$\boxed{-6x+y=43}$

What is the area of this partial circle with a radius of 14 inch

AveGali [126]

Step-by-step explanation:

Since this circle is partial we will divide the area of the whole circle by 2

the area of a circle is expressed by $\pi r^2$ so insert 14 for the radius.

$14^2\pi$

$196\pi$

divide the area by 2

$98\pi=307.876$

Hope that helps :)

Answer: 2 and three-fourths (2 3/4)

Step-by-step explanation:

11 * 1/4

1/4 = 0.25

0.25 * 11 = 2.75

.75 = 3/4

Suppose you have a cache of radium, which has a half-life of approximately 1590 years. how long would you have to wait for 1/5 o

lubasha [3.4K]

<span>You would have to wait 318 years for 1/5 (20%) of the Radium to disappear. 1590 is the point where half of the Radium would decay, so if you take 20% of that, it would equate out to 318 years. Radium has a long half life!</span>
