An article in a psychology journal claims that young students who play a musical instrument tend to have
higher test scores on state math exams.
Which statement most likely describes the relationship
between playing an instrument and state math exam
scores?
O Playing a musical instrument causes a student to
become better at solving math problems.
Students who do not play musical instruments do
not have high scores on state math exams.
O Students who have high math scores should be
encouraged to play a musical instrument so they
become proficient with music as well.
Students who play a musical instrument tend to
excel in other skills, which may explain their higher
math scores

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

step-by-step explanation:

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
