Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: <em>$95 + $55 = $150</em>
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: <em>There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55. </em>
c. What is the total cost for x months? (Write an equation for the situation.)
answer for c: <em>95 + 55x = y</em>
The ratio of the problem is 3:5.
To solve for 5, divide both sides by 5.
3/5 = .60
5/5 = 1
The ratio is .60:1.
There are .60 pints of water for every 1 pint of fruit juice.
Answer: y=1,5x-8
Step-by-step explanation:
At first transform the equation
2x+3y=18
3y= 18-2x
y= 6 - (2/3)x
The linear function has general form, which looks like that:
y=mx+n
perpendicular means that m1*m2=-1
In our case m1= -(2/3) and m2 is unknown
(-2/3)*m2= -1
m2=3/2 so m2=1,5
The line has to go through the point (6,1)
so 1=6*1,5+n
1=9+n
n= -8
so the function looks like that y=1,5x-8
X letter is formed by two lines. The minimum amount of cubes that one side may have to look a line that cross other line is 3, but given that one cube is shared by the two lines you only need 5 cubes. So the answer is that the fewest unit cubes that Peter can use to build the figue in the shpe of X is 5 cubes.
