write the equation of the line using the given information. type your awnser in slope intercept form,y=mx+b​
faltersainse [42]

Answer:

y=3/-1x+4

Step-by-step explanation:

Okay so first thing you need to know is that if there is an ordered pair (x, y) where x is 0, your y-intercept is your y. For example, your problem has (0, 4) your x is 0 and your y is 4. Therefore your y-intercept is 4 which is the b. To find your mx, or slope, you need to do (y2-y1)/(x2-x1). Your y2 will be your y in your second ordered pair and your y1 will be in your y in the first ordered pair. Same for your x. So, (4-1)/(0-1) which equals 3/-1. 3/-1 is your slope. So, your answer in slop intercept form is: y= 3/-1x+4. You could also try y= -3x+4 if that makes you more comfortable.

I know this is long this is my first time doing this lol.

To complete the square, how do you find the value that must be added to the expression to make a perfect square trinomial? What
Molodets [167]
Take half of the coefficient of x (which is 2/5) and square it:

[ (1/2)(2/5) ]^2 = (1/5)^2 = 1/25, or 0.04

Thus, to rewrite x^2 + (2/5)x to include a perfect square trinomial,

x^2 + (2/5)x  = x^2 + (2/5)x + (1/5)^2 - (1/5)^2, or

                 (x+1/5)^2 - (1/5)^2, or (x + 1/5)^2 - 1/25

The circumference of a circle is given by the formula C=2πr. Find r if the circumference is 396 meters and π is 22/7.
larisa86 [58]

Answer:

r = 63 meters

Step-by-step explanation:

C=2πr

We know pi and C

396 =  2*22/7*r

396 = 44/7 *r

Multiply each side by 7/44 to isolate r

396*7/44 = 7/44 *44/7 *r

63 =r
