Compare the average score of a student at the beginning of a month and at the end of that month, if at first, it increased by 40

IceJOKER [234]

Answer:

Increased by 5%

Step-by-step explanation:

Let at the beginning the student's score be $s$ points.

At first, it increased by 40%. So, the new score is

$s+0.4s=1.4s$

Then it decreased by 25%, so the new score is

$1/4s-0.25\cdot 1.4s=1.4s-0.35s=1.05s$

At the beginning of a month the score was $s$ and at the end of that month the score was $1.05s$ . Since $1.05>1,$ the score increased by $1.05-1=0.05=5\%$

Which point-slope form passes through the point (-2, -1) and has slope 5?

guajiro [1.7K]

Answer:

D. (y+1)=5(x+2)

Step-by-step explanation:

Point-slope form follows: y - y1 = m(x - x1)

Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.

m(slope)=5

y-(-1)=5(x-(-2))

y+5=5(x+2)
