Find the point-slope equation of the line contains (-2,-3) and having slope m=4
Answer:
y + 3 = 4 x (x + 2)
Step-by-step explanation:
point slope formula is y-y1 = m(x-x1)
slope intercept form is y = 4x + 5
y=mx +b
m=4

Step-by-step explanation:
Two people are driving to work at different constant speeds. The graph below shows the distance traveled over time by driver 1.
The table (no graph included just the table) below shows the distance traveled over time by driver 2.
What is the difference between the speeds of the two drivers in mph?
Answer:
5 mph
Step-by-sep explanation:
To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.
Unit rate/speed = distance travelled/time = y/x.
Speed of Driver 1/unit rate:
The graph shows 1.5 miles (y) is travelled in 2 minutes (x).
Convert the 2 minutes to hour, you will have:
[tex] \frac{2}{60} = \frac{1}{30} hr [/tex]
Speed in mph = [tex] \frac{y}{x} = \frac{1.5}{\frac{1}{30}} = 1.5*\frac{30}{1} = 45 [/tex]
Speed of Driver 1 in mph = 45 mph
Speed of Driver 2/unit rate:
The table shows 2.5 miles (y) is travelled in 3 minutes (x).
Convert the 3 minutes to hour, you will have:
[tex] \frac{3}{60} = \frac{1}{20} hr [/tex]
Speed in mph = [tex] \frac{y}{x} = \frac{2.5}{\frac{1}{20}} = 2.5*\frac{20}{1} = 50 [/tex]
Speed of Driver 2 in mph = 50 mph
Difference between the speed of the two drivers = 50 - 45 = 5 mph

A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 8 of the large marbles are green, and 5 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or green?
Answer: 19/25.
Step-by-step explanation:
Given data:
Large marbles = 14
Small marbles = 11.
8 large marbles = green.
5 of small marbles = white.
Solution:
If 8 of large marbles are green, therefore the remaining 6 are white.
Likewise for the small marbles the remaining 6 are green marbles.
Total number of marbles = 14 + 11
= 25.
P(small or green) = P(small) + P (green) – P (Both)
= 11/25 + 14/25 – 6/11
= 19/25
Answer:
Answer is 0.7536
Step-by-step explanation:
Large Marbles = 14 Small Marbles = 11
Green LM = 8 Green SM = 6
White LM = 6 White SM = 5
QUESTION:
If a marble is randomly selected from the box, what is the probability that it is small or it is green?
Note the use of "or" and not "and".
SOLUTION:
In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!
The formula for this probability is hence
P(A or B) = P(A) + P(B) - P(A and B)
Let A = The event that the selected marble is small
B = The event that the selected marble is green
Total number of marbles = 14 + 11 = 25
P(A or B) = 11/25 + (8+6)/25 - [P(A) × P(B)]
P(A or B) = 11/25 + 14/25 - [11/25 × 14/25]
= 0.44 + 0.56 - 0.2464 = 1 - 0.2464 = 0.7536

Vertical Line Test - A function's x-values must have only 1 corresponding y-value. If the function fails this test, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass (x = 1). Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does pass. Therefore, the 2nd graph is a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass (x = 2). Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does not pass (x = -3). Therefore, the 4th graph is not a function.
Answer:
2nd graph is correct

The Tigers, a football team, must gain 10 yards in the next four plays to keep possession of the ball. The Tigers lose 24 yards, gain 4 yards, and lose 10 yards. How many yards do they need to keep possession?
40
20
-20
-8
Answer:
B. The must gain 20 yards to keep possessionStep-by-step explanation:
Let the number of yards gained be positive
Let the number of yards lost be negative
Since the total that must be gained in the next four games is 10, hence the total is +10
If The Tigers lose 24 yards, gain 4 yards, and lose 10 yards in the first three rounds with x being the number of yards in the fourth round, this is expressed as;
-24 + 4 - 10 + x = 10
-20 - 10 + x = 10
-30 + x = -10
x = -10 + 30
x = 20
Hence they need 20 yards in the last round to keep possession

Answer:
z = -ln│5eᵗ + C│
Step-by-step explanation:
dz/dt + 5eᵗ⁺ᶻ = 0
dz/dt = -5eᵗ⁺ᶻ
dz/dt = -5eᵗeᶻ
-e⁻ᶻ dz = 5eᵗ dt
e⁻ᶻ = 5eᵗ + C
-z = ln│5eᵗ + C│
z = -ln│5eᵗ + C│
