Answer:
y=absolute value of x-1 Looks kind of like y=Ix-1I
Step-by-step explanation:
Answer:
(a^4+b^4)/(a^2b^2)
Step-by-step explanation:
Answer: The equations are A= 600 + 125w and A = 1100 + 50w. Look into the steps for more information.
Step-by-step explanation:
Zypel's situation can be represented by the equation, A= 600 + 125w where A is the amount of money she will have after w weeks.
The same way we can represent Joshua's situation by the equation
A = 1100 + 50w where a is also the amount of money he will save after w weeks.
It says that there are 4 weeks in one month which means there will be 16 weeks in 4 months.
Now input 16 into the equations for w and solve for A.
A = 600 + 125(16)
A= 600 + 2000
A = 2600
So Zypel will save $2600 in a 4 months
A = 1100 + 50(16)
A= 1100 +800
A= 1900
So Zypel will save more than Joshua in four months.
We check with each options
'Or' represents the intersection of two graphs
'And' represents two separate graphs'
We have two separate shaded part in the given graph
So we ignore the options that has 'and' in between
LEts check first and second option
Simplify the first part and second part
multiply both sides by 2 .
x < 2 or 4x - 2 > = 26
solve 4x-2 > = 26
add 2 on both sides and then divide both sides by 4
4x >= 28
x >= 7
So solution is x<2 or x>=7 . that is the graph on number line
Lets check with second option
3x-3<3 or 2x+8>=22
add 3 on both sides
3x < 6
divide both sides by 3
so x< 2
2x+8>=22
subtract 8 on both sides
2x >= 30
divide both sides by 2
x >= 15
x<2 or x>=15 that does not satisfies the graph
So option A is correct
