Answer:
4 2 8 89 8
Step-by-step explanation:
Well, since point A represents the center, and B represents a point on the outer line of the circle, segment AB would represent the radius, since the radius represents the length from the center to the outside of a circle
Hope this helps
Answer:
$175
Step-by-step explanation:
If after a 20% discount, it cost $140, the $140 is only 80% of the cost.
So divide 140 by 4 then multiply the answer by 5 to get it back to 100%
140/4=35
35x5=175
Answer:
21 and 14
Step-by-step explanation:
The relationship between x and y is proportional thus the equation is
y = kx ← k is the constant of proportion
To find k use the ordered pair y = 84 when x = 28 , then
84 = 28k ( divide both sides by 28 )
k = 3
y = 3x ← equation of proportion
When x = 7 , then
y = 3 × 7 = 21 ← value required in top table
When y = 42 , then
42 = 3x ( divide both sides by 3 )
x = 14 ← value required in lower table
We need to put ur equation in y = mx + b form ...and the m will be ur slope and the b will be ur y int
so basically, we solve for y...
2x + y = 3....subtract 2x from both sides
y = -2x + 3
y = mx + b
y = -2x + 3......slope(m) = -2 and y int (b) = 3 <==
