Answer:
B, C, D
Step-by-step explanation:
You can solve for x, or you can try x=3.5 to see if that makes the equation true. Here, we decided to solve for x.
A. x =(8×3 -3)/7 = 3
B. x = 15 -11.5 = 3.5
C. x = (34 -6)/8 = 3.5
D. x = 15.5 -12 = 3.5
E. x = 20 -15.5 = 4.5
Answer:
y =
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
m = Slope of the line
b = y-intercept
Since, slope of a line passing through two points
and
is given by,
m = 
Since, the given line passes through two points (-5, 1) and (4, -2)
Slope of the line 'm' =
= 
Equation of the line will be,
y = 
Since, this line passes through (4, -2),
-2 = 
b = 
b = 
Therefore, equation of the line will be,
y =

Answer:

Step-by-step explanation:
Assuming the maximum score for the final is
, we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of
, their overall grade for the course would be:
.
To find the minimum score they need to earn a 75% for the course, we set up the following equation:
, where
is the minimum score she needs.
Solving, we get:
.
