Answer:
AC=7.5 cm
CB=10.5cm
Step-by-step explanation:
Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm
Answer:
A.
Step-by-step explanation:
To find the inverse of a function, first make f(x) a y
So,
y = 
-18
Then switch the x and the y
x = 
- 18
Solve, for y
16y²+12y = 4y(4y+3)
D. 4y(4y + 3)
Answer:
Each person will get 5.34 ounces of soda.
Step-by-step explanation:
In order to find out how many ounces of soda each person gets we need to take the total amount of soda Magalie brought to the party and divide it by the number of people that will drink the soda. In this case we have:
amount per person = 48/9 = 5.34 ounces
Each person will get 5.34 ounces of soda.
Company A : 15h + 20
Company B : 5h + 40
when would company B be cheaper....
15h + 20 > 5h + 40 ...put the less then sign towards Company B, then solve
15h - 5h > 40 - 20
10h > 20
h > 20/10
h > 2
Company B would be cheaper when the hours (h) are greater then 2
