Simplified expression for the amount is 10(9m + 50)
Step-by-step explanation:
- Step 1: Form an equation for the amount of money Troy has received after m months.
If the total months that Troy's grandfather has given him money is m, then the number of months that Troy's mother has given him money is m - 4.
⇒ Total amount in account = 700 + 40m + 50(m - 4)
= 700 + 40m + 50m - 200
= 90m + 500 = 10(9m + 50)
The equation that represents the relationship between x. the number of hours of swimming lessons, and y the total amount charged it will be given by y=25x+50
The y-intercept of the equation is 50 means that the one-time registration fee for swimming lessons is $ 50
Hidden Treasures Walking Tour:
y= 9 x 6 + 25
= 79
Road-Less-Traveled Tours:
the function is y= 12x
y= 12 x 6 = 72
Bowman Bros:
The line is y -30 over x -1 = 50 - 30 over 3 - 1
y= 10x + 20
y= 10 x 6 + 20 = 80
72 < 79 < 80
So chose Road-Less-Travelled Tours
Answer:
Equation 2 represents the greatest value of x!
Step-by-step explanation:
Let's solve each equation for x.
Equation 1; x = 4.1 (about)
Equation 2: x = 5 (about)
Equation 3: x = 4 (exact)
Equation 4: x = 3 (exact)
Hope this helps. :)
I believe it is B because the y intersect is +6 and they slope is going down so it is -2
