Answer:
z=4, y=11, x=1
Step-by-step explanation:
The sides don't change when a shape is reflected over,
so we can use the other sides to find the variables.
3z=12, so z=4. 2y-4=18, so y=11. 9x+6=15, so x=1

have a great day :) also this anwser is 100% correct. i tested it.
Answer:
y = -6x + 30
Step-by-step explanation:
The inicial value you have is $30, so this will be the value of y after 0 weeks, that is, x = 0
After one week, you spend $6, so you will have y = 30 - 6 = 24 when x = 1.
With these pair of values, we can find the linear equation:
y = ax + b
for x = 0, y = 30:
30 = a*0 + b
b = 30
for x = 1, y = 24:
24 = a*1 + 30
a = 24 - 30 = -6
So, our equation is:
y = -6x + 30
Answer:
B) 7v^3-15v^2-17v-3
Step-by-step explanation:
(v-3)(7v^2+6v+1)
7v^3+6v^2+v-21v^2-18v-3
7v^3+6v^2-21v^2+v-18v-3
7v^3-15v^2-17v-3
1/4 = 3/12
3/12 < 5/12
Therefore, 5/12 is greater than 1/4
