Answer:
y = 15.75x + 25 is the linear equation
$88 would be the total cost
Step-by-step explanation:
First, create the equation using y = mx + b, where x is the number of hours:
y = 15.75x + 25 will be the equation, since the charge is $15.75 per hour and the flat fee is $25
There are 4 hours in between 8:30 AM and 12:30 PM, so to find the cost, plug in 4 as x and simplify:
y = 15.75x + 25
Plug in 4 as x:
y = 15.75(4) + 25
y = 63 + 25
y = 88
So, the total cost would be $88
I’m pretty sure it would be angle 3 and angle 5 and then angle 1 and angle 7
You just need to substitute 4(2)-2(5)/2
8-10/2
8-5
=3

If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
Hope this helps. :)
