Answer:
B) y = (-7X/5) + 4
Step-by-step explanation:
Recall two lines are perpendicular if their slopes are negative reciprocals (5/7 goes to -7/5).
Assuming in the form y = mx + b:
Solving for b:
-7/5(-5) + x = 11
(5's & negatives cancel out...)
7 + x = 11
x = 4
y = -7/5x + 4
Answer:
g + 1
Step-by-step explanation:
(2g + 6) - (g + 5)
Distribute the negative
2g + 6 - g - 5
Combine like terms
2g - g + 6 - 5
g + 1
Answer:
1/2D meters
Step-by-step explanation:
I hope this helps
Theoretical: desired outcomes/total possible outcomes
the same as it was his first time picking before since the prevous results have no bearing on what this trial will yeild
if he didn't replace the marbles then it would be differnt
experimintal=number of event occurnces/total number of trials
so 4/4 or 100% is experimental
so
equal number of red and black and white
1/3 of the bag is black
therefor the probablity of picking a black marble is 1/3
A. 1/3 is theoretical, 4/4=experimental
B. differnce? dunno sorry
C. 4 in a row
1/3*1/3*1/3*1/3=1/81
Please see the attached figure. This is how you draw a hyperbola. Its general formula is:
(x-h)²/a² - (y-k)²/b² = 1, where
(h,k) is the center
a is the semi-major axis
b is the semi-minor axis
The given equation is
(x+4)²/16 - (y+3)²/25 = 1
So, from the general form we can deduce that,
Center(-4,-3)
a = 4
b = 5
So, the first point we can plot is the centerpoint. Next, you draw the two intersecting lines. Their slopes are +/- b/a. Thus, it corresponds to +/- 5/4. Using this slope, we can find the equation of the two lines by using the slope and the center.
-3 = +5/4 (-4) + b ---> b= 2
-3 = -5/4 (-4) + b ---> b= -8
So, you plot the equations y=5/4x + 2 and y = -5/4 x -8 by assigning values of x and plotting them against y. Then, the vertex of the hyperbolas are 4 units from the center, denoted by the green dots. The hyperbola is shown in the next picture.
