Answer:
Step-by-step explanation:
find all of tehe factors to both numbers
15x = 5 3 x
35 = 5 7
pull 5 out of both of them and put the remaining factors in parentheses
5(3x + 7)
Answer:
j(x) = 5 |x+9|-23
Step-by-step explanation:
f(x) = |x|
translate left 9 units
y = f(x + C) C > 0 moves it left
g(x) = |x+9|
translate down 23 units
y = f(x) + C C < 0 moves it down
h(x)= |x+9|-23
stretch by a factor of 5
y = Cf(x) C > 1 stretches it in the y-direction
j(x) = 5 |x+9|-23
STEP 1:
Add the number of total students
= 27+25+23
=75
STEP 2:
Find the percentage that 18 out of 75 students is.
18/75=x/100
cross multiply
(18*100)=(75*x)
1800=75x
divide both sides by 75
24%=x
Check:
75 * 24%= 18
Hope this helps! :) Good luck!
