Answer: x ≤ -4
Step-by-step explanation: The explination will be placed in the comment area :)
Answer:
120π
Step-by-step explanation:
diameter = 120
radius = 60
Cirumference= 2πr
2 x π x 60 = 120π
Answer:
x = 12 cm
Step-by-step explanation:
The product of lengths from the secant intersection point to the "near" and "far" circle intersection points is the same for both secants. When one "secant" is a tangent, the lengths to the circle intersection points are the same (so their product is the square of the tangent segment length).
8^2 = 4·(4 +x) . . . . . . measures in centimeters
16 = 4 +x . . . . . . divide by 4
12 = x . . . . . . . . . subtract 4
Answer:
y = 4 and x = 12
Step-by-step explanation:
Step by step explanation in the pic. Atleast the way I did it.
Answer:
Step-by-step explanation:
those are 2 lines, and to graph them find 2 points for each to draw a line trough them
line 1
y-2x=0 so y=2x
pick any value for x
(x=1, y=2*1=2), (x=3, y=2*3=6)
Draw a line trough points (1,2) and (3,6)
line 2
y=4x+3
(x=1, y=4*1+3=7), (x= -1, y= 4(-1)+3= -1)
Draw a line trough points (1,7) and (-1, -1)
