How many solutions does this system have? no solutions one unique solution O O two solutions O or an infinite number of solutions
Answer:
no solutions
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
equation of blue line is y = x + 2 , in slope- intercept form
with slope m = 1
equation of red line is y = x - 3 , in slope- intercept form
with slope m = 1
• Parallel lines have equal slopes
then the blue and red lines are parallel.
the solution to the system is at the point of intersection of the 2 lines
since the lines are parallel then they do not intersect each other.
thus the system shown has no solution.

The total number of rabbits bought by Doña Rose for your farm is 4 times the Number of given rabbits.
The number of rabbits bought by Doña Rose for your farm, we need to consider that the given rabbits represent only a quarter of the total number.
the total number of rabbits as 'x'. According to the information, the given rabbits represent a quarter of 'x', which can be expressed as:
Given rabbits = (1/4) * x
To find the value of 'x', we can multiply both sides of the equation by 4
4 * Given rabbits = x
Therefore, the total number of rabbits bought by Doña Rose for your farm is 4 times the number of given rabbits.
the exact value of 'x'. However, we can state that the total number of rabbits bought is four times the number of the given rabbits.
So, if the given rabbits represent 'n' in quantity, the total number of rabbits bought would be 4n.

On a number line, point C is at 8, and the midpoint E of CD is at -3.
Point D is at
on the number line.
Answer: C
Step-by-step explanation:
Point D is at -14 on the number line.
How to determine the midpoint of a line segment?In Mathematics, the midpoint of a line segment with two end points can be calculated by adding each end point on a line segment together and then divide by two (2).
Since E is the midpoint of line segment CD, we can logically deduce the following relationship:
Line segment CD = Line segment C + Line segment D
Midpoint E = (point C + point D)/2
By substituting the given points into the equation above, we have the following:
-3 = (8 + D)/2
-6 = 8 + D
D = -6 - 8
D = -14

Here's a graph of a linear function. Write the
equation that describes that function.
xpress it in slope-intercept form.
Answer:
the slope intercept form is y = (1/2)x - 1
Step-by-step explanation:
The slope-intercept form is, y = mx + b
We see from looking at the graph that,
at x = 0, y = -1
So, from this we find that b = -1
at x = 2, y = 0,
now, we find the slope m,
using,
\(m = \frac{y_{2} -y_1}{x_2-x_1}\)
Using x_2 = 2, y_2 = 0,
x_1 = 0, y_1 = -1, we get,
m = (0-(-1))/(2-0)
m = 1/2
So, the slope intercept form is,
y = (1/2)x - 1

A new car is bought for $100,000. If the annual depreciation is 10%, find the value of the car after 3 years.
Remaining Amount = 100,000(1 -0.1)3

How to determine the valueTo determine the value, we have to use the formula;
Value = Initial value × (1 - Depreciation rate)ⁿ
Substitute the values given, we get;
Remaining value after 3 years = $100,000 × (1 - 0.10)³
Expand the bracket, we get;
Value after 3 years = $100,000 × (0.90)³

Let the random variable X be equal to the number of days that it takes a high-risk driver to have an accident. Assume that X has an exponential distribution. If P(X < 50) = 0.25, compute P(X > 100 | X > 50).
The detailed answer of this question is:
P(X > 100 | X > 50)=0.455
Given that X follows an exponential distribution, we know that the probability density function (PDF) of X is given by:
f(x) = λe^(-λx) for x ≥ 0
where λ is the rate parameter of the distribution.
We are given that P(X < 50) = 0.25. Using the cumulative distribution function (CDF) of X, we can write:
P(X < 50) = 1 - e^(-λ*50) = 0.25
Solving this equation for λ, we get:
λ = -ln(0.75)/50 ≈ 0.0278
Now, we are asked to find P(X > 100 | X > 50). Using the definition of conditional probability, we can write:
P(X > 100 | X > 50) = P(X > 100 and X > 50) / P(X > 50)
= P(X > 100) / P(X > 50)
= e^(-λ100) / e^(-λ50)
= e^(-λ*50)
Substituting the value of λ, we get:
P(X > 100 | X > 50) = e^(-0.0278*50) ≈ 0.455
Therefore, the probability that a high-risk driver will have an accident after 100 days given that they have not had an accident for the first 50 days is approximately 0.455.

The function f(x) = -2(4)^x+1 +140

What is the practical domain and range of the function?
If necessary, round to the nearest hundredth.
The practical domain of the situation is ?
The practical range of the situation is ?
PLEASE SEE PHOTO FOR FUNCTION
The function f(x) = -2(4)ˣ⁺¹ +140 represents the number of tokens a child has x hours after arriving at an arcade. The practical domain and range of the function are x ≥ 0 and The practical range of the situation is [140, ∞).
The given function is f(x) = -2(4)ˣ⁺¹+ 140, which represents the number of tokens a child has x hours after arriving at an arcade.
To determine the practical domain and range of the function, we need to consider the constraints and limitations of the situation.
For the practical domain, we need to identify the valid values for x, which in this case represents the number of hours the child has been at the arcade. Since time cannot be negative in this context, the practical domain is x ≥ 0, meaning x is a non-negative number or zero.
Therefore, the practical domain of the situation is x ≥ 0.
For the practical range, we need to determine the possible values for the number of tokens the child can have. Looking at the given function, we can see that the term -2(4)ˣ⁺¹represents a decreasing exponential function as x increases. The constant term +140 is added to shift the graph upward.
Since the exponential term decreases as x increases, the function will have a maximum value at x = 0 and approach negative infinity as x approaches infinity. However, due to the presence of the +140 term, the actual range will be shifted upward by 140 units.
Therefore, the practical range of the situation will be all real numbers greater than or equal to 140. In interval notation, we can express it as [140, ∞).
To summarize:
- The practical domain of the situation is x ≥ 0.
- The practical range of the situation is [140, ∞).

A new drug claims to reduce the number of epileptic seizures an individual with epilepsy diagnosed before the age of 4 years
old. In a study on the effectiveness of the new drug, 300 subjects were given the new drug and another 300 subjects were
given a placebo.
At the end of the 1-year study, the group given the new drug reported an average of 1.3 epileptic in the year. The group given the
placebo reported an average of 3.1 epileptic seizures in the year.
The data from the study are rerandomized 10 times. The difference of the means from rerandomization are
1.2, 2.4, 1.8, 1.3, 2.1, 0.9, 1.5, 0.7, 2.1, and 2.3.
What is the most appropriate conclusion about the new drug to draw from this information?
The new drug appears to reduce epileptic seizures since the rerandomized mean differences are considerably less
than the mean difference found between the two groups studied.
The new drug does not appear to reduce epileptic seizures since the rerandomized mean differences are close to
the mean difference found between the two groups studied.
The new drug does not appear to reduce epileptic seizures since the rerandomized mean differences are
