Answer:
A)3.74
B)17.04
C)61.92
Step-by-step explanation:
The equation of the line of best fit:

Where x is time in hours
y = midterm score
a)For an increase of one hour in the time spent studying, what is the predicted increase in the midterm score?
General equation y = mx+c
where m is the slope .
On comparing m = 3.74
Slope is the rate of increase per hour
So, For an increase of one hour in the time spent studying, the predicted increase in the midterm score is 3.74
b)What is the predicted midterm score for a student who doesn't spend any time studying?
Substitute x = 0
y=3.74x+17.04
y=3.74(0)+17.04
y=17.04
c)What is the predicted midterm score for a student who studies for 12 hours?
Substitute x = 12
So,y=3.74x+17.04
y=3.74(12)+17.04
y=61.92
Answer:
No
Step-by-step explanation:
The point is not in the shaded section. Every single point on the shaded section is a solution.
Given:
The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is

Using this rule, we get



Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).
Up is the y value and left is the x value.
In the point ( t,u) t is the x value and u is the y value.
Moving to the left, you subtract the value and moving up you add the value.
The answer would be (t, u) → (-t – 3, u + 8)
