Answer:
4
Step-by-step explanation:
y=3 is a horizontal line, so it will not affect the x coordinate.
The x-coordinate of the image when M(4,-1) is reflected in y = 3 is : 4
What is reflection?Reflection is the mirror image of a shape.
It is the process of flipping a shape around a certain axis to look like the original shape.
Analysis:
Since the reflection is at y = 3 which is along the x-axis, only the y coordinate changes. The x coordinate remains the same. So, the x- coordinate is still 4.
In conclusion, the x-coordinate is 4.

The graph below shows the height through which an elevator travels, y, in x seconds:
A graph is shown with x-axis title as Time in seconds. The title on the y-axis is Height of Elevator Above Ground in feet. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 75 in increments of 15 for each grid line. A line is shown passing through the ordered pairs 1, 15 and 2, 30 and 3, 45 and 4, 60. The title of the graph is Rate of Ascent.
What is the rate of change for the relationship represented in the graph?

15
Answer:
D. 15Step-by-step explanation:
Rate of change is:
The change in the height over change in timem = (y2 - y1) / (x2 - x1)Substitute values with ordered pairs:
m = (60 - 15)/(4 - 1)m = 45/3m = 15Correct option is D. 15
Answer:
A line is shown passing through the ordered pairs (1, 15) and (2, 30) and (3, 45) and (4, 60).
The rate of change of height :---
[tex]slope( = m) = \frac{(60 - 15)}{(4 - 1)} = \frac{45}{3} = 15\\[/tex]
D. 15 is the right answer.Which function has an inverse that is also a function?
Can someone please help me with this problem?
Answer:
The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].
Step-by-step explanation:
The only function whose inverse is also a function is the linear function, also named first-order polynomial. The inverse of a linear function is also a linear function. That is:
[tex]y = \frac{1}{3}\cdot x -\frac{3}{4}[/tex]
[tex]\frac{1}{3}\cdot x = y + \frac{3}{4}[/tex]
[tex]x = 3\cdot y + \frac{9}{4 }[/tex]
The function that has an inverse that is also a function is [tex]x = 3\cdot y + \frac{9}{4 }[/tex].

Write an equation that represents the remaining number of meals y, after x number of hours. (❍ᴥ❍ʋ)help please
Answer:
y=600-55x
Step-by-step explanation:
Since there is a total of 600, and there is 55 being taken away every hour, there needs to be the x next to the 55, and then that will get you the amount of meals remaining, which is y.

Select all angles that have a cosine of 9/15
Answer:
Step-by-step explanation:
All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Triangle PQR is similar to triangle XYZ.
Hence, We get;
In triangle PQR,
cos P = 9/15
And, In triangle XYZ,
cos X = XZ / ZY
cos X = 9 / 15
Thus, All the angles that have a cosine of 9/15 are,
⇒ ∠P and ∠X

N= 17 and P=0.8 is it suitable to use a normal distribution
Answer:
Since n(1-p) < 10, it is not suitable to use a normal distribution.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 10
n(1-p) >= 10
In this question, we have that:
n = 17, p = 0.8. So
np = 17*0.8 = 13.6 -> Ok
n(1-p) = 17*0.2 = 3.4 -> No
So, since n(1-p) < 10, it is not suitable to use a normal distribution.

Answer:
120 degrees.
Step-by-step explanation:
All the angles in a triangle add up to 180. You have two of the angles given:
50 degrees and 70 degrees
To find the third angle of the triangle (BAC), use the expression:
180 - (50 + 70)
180 - 120
60
So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.
