Answer:
x=9
Step-by-step explanation:
We have two similar triangles because both lines are parallel, use proportions to solve:

Generally plug 0 in for x and solve for y. whatever y is is your y intercept

A parent increases a child’s monthly allowance by 20% each year. If the allowance is $8 per month now. This is an exponential function, An exponential function is given by:
Let x be the number of years and y be the allowance. The initial allowance is $8, this means at x = 0, y = 8
Since it increases by 20% each year, i.e 100% + 20% = 1 + 0.2 = 1.2. This means that b = 1.2
Therefore:
To find the number of years will it take to reach $20 per month, we substitute y = 20 and find x
x = 6 years to the nearest year
Answer:
total number of students is 25
AIZA AND GLAIZA came 60% of the 25 students that is 15th position

B) Students who has scored greater than them were=> 15-2=13 (as they niether got less than 12 nor more than 12.)
