Answer:
One
Step-by-step explanation:
6z - 3z - 7 = -2 + 3
Combine like terms
3z-7 = 1
Add 7 to each side
3z-7+7 = 1+7
3z=8
Divide each side by 3
3z/3 = 8/3
z = 8/3
There is one solution
The wording "earns 8% interest each year" does not make it clear whether the savings account interest is compounded. (It usually is in real life, but not always in math problems.) The graphical solution shows both simple interest and interest compounded annually.
Simple interest: the balances will both be $2941.18 after 5.88 years.
Compound interest: the balances will both be $3111.06 after 5.74 years.
Answer:
1. y = x + 7
Step-by-step explanation:
Find the slope
Choose two points and find the slope using rise/run
(1,8) (2,9)
9-8/2-1
1/1 = 1 = m (slope)
Find b using the slope and one point
m=1 (1,8)
8 = 1 (1) + b
8 = 1 + b
7 = b
Fill in m and b into y = mx + b
y = 1x + 7
Answer:
The player will not make the team.
Step-by-step explanation:
To find the percentage he is shooting, divide the number he has made by the number he has taken.
9/15 = 60%
60% is less than the needed 65%
