Answer:
b There is No Solution for this system
Step-by-step explanation:
When graphing out equations, the two equations have to intersect at one point to have a solution. If they are parallel, it means that they will never intersect at one point and thus there is no solution for the system. A pair of lines would only have infinitely many solutions when both lines are at the same position travelling in the same direction, overlapping each other.

There are 130 people in a sport centre. 61 people use the gym.
68 people use the swimming pool.
60 people use the track.
25 people use the gym and the pool.
30 people use the pool and the track.
19 people use the gym and the track.
6 people use all three facilities.
Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?
Answers
Step-by-step explanation:
Number of people who uses the gym and the track, and also uses the pool = Number of people who use all 3 facilities = 6. (given)
Number of people who uses the gym and the track, and may or may not use the pool = 19. (given)
Therefore number of people who use the gym and track, but do not use the pool = 19 - 6 = 13.
Probability = (13/19) * 100% = 68.4%.

n = -4 because youre finding the n
Answer:
n = -9
Step-by-step explanation:
Multiply 2 by both sides to cancel out the fraction which will leave -5 + n = -14. Lastly add 5 on both sides which the final answer would be n = -9.

Answer:
The graph of f is shifted 6 units up to create the graph of g
Option A is correct option.
Step-by-step explanation:
We are given f(x)=x
and g(x)=f(x)+6
We need to find how f(x) and g(x) are related.
We know that according to translation rules:
if we have f(x) as original graph and f(x)+d as translated graph it means the original graph f(x) is shifted d units up.
So, in our case f(x)=x
g(x)=f(x)+6
The graph of f is shifted 6 units up to create the graph of g
Option A is correct option.
In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 100 fewer people went to the pool than in the first week. In the third week, 140 more people went to the pool than in the second week. In the fourth week,146 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answers
Answer: 10%
Step-by-step explanation:
As per given ,
Initial number of people went to pool = 1060
After 4 weeks periods, number of people went to pool = 1060 - 100 +140 -146 ['+' for addition . '-' for decrease]
= 954
The percent decrease in the number of people who went to the pool over these four weeks = [tex]\dfrac{1060-954}{1060}\times 100[/tex]
[tex]=\dfrac{106}{1060}\times100\\\\=10\%[/tex]
Hence, the percent decrease in the number of people who went to the pool over these four weeks = 10%

find the slope of a line that intersects the points (-2,6) and (4,-4)
hurry i’ll give 20 points
Answers
First find the slope of the line connecting these two points:
6-5
m = ------------ = -1/2
-4+2
Substitute this slope into y = mx + b: y = (-1/2)x + b.
Next, subst. 5 for y and -2 for x, and find b:
5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and
the equation of the line is y = (-1/2)x + 4.
A bee flies at 6 feet Per second directly to a flower bed from its hive. The bee stays at the flower bed for 19 minutes, and then flies directly back to the hive at 4 ft per second. Is away from the high for a total of 24 minutes. What equation can used to find the distance of the flower bed from the hive? How far is the flower bed from the hive?
Answers
Answer:
720 feet
Step-by-step explanation:
We can Find the travelling time. We know that the bee spends 19 minutes hunting down the nectar in the flowerbed. But was away from the hive for a total of 24 minutes, then the travelling time becomes(24min - 19min) = 5 min
Then let us Convert to seconds vfir consistency
1 minute = 60 seconds
5 minutes = (5×60 )= 300 seconds.
Then the travelling time becomes 300 seconds
We can Find the time each way, since we know that the total time is 300 seconds, though not evenly divided
Let us denote the time there = t
the time back = (300 - t)
But the distances are the same.
r = 6 m/s and r1 = 4 m/s
t1 = t and t2 = (300 - t)
Let dthere = dback
Where, d =( rate × time)
(6× t )= 4 (300 - t)
6t= 1200 - 4t
10t=1200
t=120 seconds
To Find the distance?
d =( rate × time)
d = ? r = 6 m/s and t = 120 second
d = r*t
d = 6 × 120
= 720 feet
Hence, instance of the flower bed from the hive is 720 feet while the equation is ( d = r*t)

Is the discriminant of g positive, zero, or negative?
Answers
Answer:
The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.
Step-by-step explanation:
The discriminant of the quadratic equation g is negative.
In algebra, the discriminant of a quadratic equation plays a crucial role in determining the nature of its roots. For a quadratic equation of the form ax² + bx + c = 0, the discriminant is given by Δ = b² - 4ac. Depending on whether the discriminant is positive, zero, or negative, we can determine the types of roots the equation possesses.
When the discriminant is negative, it implies that the quadratic equation has no real roots. In this case, the graph of the quadratic equation does not intersect the x-axis at all, indicating that it has complex roots. These complex roots are a pair of complex conjugates of the form (p + qi) and (p - qi), where p and q are real numbers and i is the imaginary unit (√(-1)).
