Step-by-step explanation:
A) Let X= the number of weeks 46 times 3/4 = 72. And 135+72 x >_ 580
B) 135+72 x >_ 580. 580-135. 72/72 >_ 445/72
x >_ 6.2
She must work a minimun of 7 weeks to get $580.
Answer: D)3.5h+4
Step-by-step explanation:
Let h denotes the number of hours that the ice skates are rented.
Since, The cost of renting ice skates is $4 plus $3.50 for each hour that the ice skates are rented.
So , the total cost for ice-skating = $4 + $3.50 x (number of hours that the ice skates are rented.)
= 4+3.50 x ( h) [as expression]
Hence, the expression can be used to find the cost in dollars of renting ice skates for h hours :-

When rewritten your equation in the problem is y=x-2
You need to find an answer that when put with the equation above, cancels it out resulting in no solution because the slopes are the same
The equations rewritten are
y=5
y=x-4. This one is the answer.
y=-x+2
y=-x+2
You plug in y=x-2 into y=x-4 so it’s
x-2=x-4
The Xs will camel resulting in no solution
14 is that answer but I am not sure how to show my work on here
