Set the to equal:
x^2 - 4x+4 = 2x-4
solve for X
subtract 2x from each side:
x^2 -6x + 4 = -4
subtract 4 from each side:
x^2 -6x = -8
add 8 to both sides:
x^2 -6x +8 = 0
factor the polynomial:
x = 4 and x = 2
using the line equation replace x with 2 and 4 and solve for y
y = 2(2) - 4 = 0
y = 2(4)-4 = 4
so the 2 points the line crosses the curve is (2,0) and (4,4)
using those 2 points you can calculate the length:
distance = sqrt((x2-x1)^2 +(y2-y1)^2
distance = sqrt( (4-2)^2 + (4-0)^2)
distance = sqrt (2^2 + 4^2)
distance = sqrt (4+16)
= sqrt 20
= 2 sqrt(5) EXACT LENGTH
4m - 3 = 100
4m = 103
m = 25 3/4
Hope this helps!
-9x+2y = -36
when x=0 ; 2y = -36
so y = -18
then y-intercept(x=0) is -18
Answer:
Let A1 be original area
A2 dilated Area
A1=pi*d^2/4
=3.143*5^2/4
A1=19.63 unit square
A2= 3.143*15/4
A2=176.74 unit square
A2 is 9 times greater than A1
Hence the answer is B
Step-by-step explanation:
Do 180 and subtract 171 so 9
