Complete the equation of the line through <br> (-8,8) and (1,-10).<br> use exact numbers <br> Y=
lyudmila [28]

Answer:

Step-by-step explanation:

Find the equation of the line thru the points (2,1) and (3,5)

---------------------

This is a 2 step process. First find the slope of the line thru the points.

slope, m = diffy/diffx

m = (5-1)/(3-2)

m = 4

---------

Now use y = mx + b with either point to find b, the y-intercept.

y = mx + b

5 = 4*3 + b

b = -7

The line y=5x+b is tangent to the graph y=/x at the point P= (a,/a) Find P and determine b.
Naily [24]
P = (1/100 , 1/10)
b = 1/20
Equate both equations. Use the substitution y=/x (/ means square root). Obtain an equation in terms of y. 5y2 - y + b = 0 Use b2 - 4ac = 0 for tangent. You'll get the answer for b then replace in equation, overall 5y2 - y + 1/20 = 0. Use the quadratic formula to solve for y. You'll obtain y = 1/10 as answer. Using the substitution y=/x, x=y2, x = (1/10)2 = 1/100, /x = 1/10. 5y2 and (1/10)2 are ...to the square....5y to the power of 2.

The number 2400 is first increased by 30%.The value obtained is next decreased by 20%.Find the final number
kvasek [131]

<em>2400 is increased by 30%.</em>

so,

2400 + (30/100 * 2400)

2400 + (30 * 24)

2400 + 720

3120

<em>this number is decreased by 20%.</em>

so,

3120 - (20/100 * 3120)

3120 - (2 * 312)

3120 - 624

2496

therefore, the final number will be 2496.
