Answer:
y = -2x+4
Step-by-step explanation:
points (1,2) (4,-4)
slope = (y2-y1)/(x2-x1)
= (-4-2)/(4-1)
= -6/3
= -2
point slope form
y-y1= m(x-x1)
y-2 = -2(x-1)
to change to slope intercept form
distribute
y-2 = -2x+2
add 2 to each side
y = -2x+4
Answer:
<h2>(4, -6)</h2>
Step-by-step explanation:
The formula of a midpoint of the segment AB:
We have A(7, -2) and B(1, -10). Substitute:
Answer:
Probability (Roulette ball not landing on red) = 10 / 19
Step-by-step explanation:
Given:
Number of total slots = 38
Number of red slots = 18
Number of black slots = 18
Number of green slots = 2
Find:
Probability (Roulette ball not landing on red)
Computation:
Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)
Probability (Roulette ball not landing on red) = 1 - (18 / 38)
Probability (Roulette ball not landing on red) = 20 / 38
Probability (Roulette ball not landing on red) = 10 / 19
Answer:
8.4 inches
Step-by-step explanation:
You divide 1 3/4 by 2 1/2 then multiply by 12
So this is ratios
actual height to shadow height=10 to 18=10:18=10/18=5/9
ratio is 5:9
if the shadow height=12 then find actual height
x:12=5:9 since they should be in the same ratio
x/12=5/9
multiply both sides by 12
x=60/9
x=6 and 6/9
x=6 and 2/3
height of person is 6 and 2/3 foot or 6.66ft or 6ft and 8 inches
