Answer:
1.D
2.c
Step-by-step explanation:
f(m/4)=8(m²/16)-4(m/4)
=m²/2-m
f(-4)=-3(-4)²+5(-4)
=-3(16)-20
=-48-20
=-68
If the 1m turns into 3m then he cm increases also by 3.The 3 meters would equal 300 cm.
Account balance is not proportional to the number of weeks.
Answer: x=19
Step-by-step explanation:
a triangle always=60 so
14+12+15=41
41-60
=19
Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.
