Answer:
y = 0.03x + 70
Slope here represents the variation in the charges with the change in the number of flyers
Positive slope means that the cost is increasing with increase in number of flyers
Step-by-step explanation:
Given:
for 100 copies advertiser is charged = $73
For 400 copies advertiser is charged = $82
Now,
here the charge is a function of number of flyers
we have the general line equation for a linear relationship as:
y = mx + c
here m is the slope
c is the constant
for the first case we have
y = $73
x = 100
thus,
73 = 100m + c ...........(1)
for the second case, we have
y = $82
x = 400
thus,
82 = 400m + c ...........(2)
subtracting (1) from (2)
82 = 400m + c
- ( 73 = 100m + c )
==================
9 = 300m + 0
or
m = 0.03
substituting the value of slope in equation (1)
73 = 100 × 0.03 + c
73 = 3 + c
or
c = 70
Hence,
the equation is y = 0.03x + 70
here y is amount charged and x are the number of flyers.
Slope here represents the variation in the charges with the change in the number of flyers
Positive slope means that the cost is increasing with increase in number of flyers
Since you know the amount of what she earns you would use the number 15 and you dont know how long she worked you would put "x" next to the 15. so you would have 15x and then put a plus 5 to show her transportation fee. so you would have the equation of 15x+5:) and instead of x use h to show hours because h=hours
you feel me?
great!
Step-by-step explanation:
c >= 2
that means any value of c greater or equal to 2 is a valid solution. so, yes, 2 is a solution for this.
c < 2
that means any value of c smaller than 2 is a valid solution. so, no, 2 is not smaller than 2, so it is not a solution.
c < 3
that means any value of c smaller than 3 is a valid solution. so, yes, 2 is smaller than 3, so 2 is a solution.
3 < c
that means any value of c, for that 3 is smaller, is a valid solution. our in other words, any value for c larger than 3 is a valid solution. so, no, 2 is not larger than 3, so it is not a solution.
-8 < c
that means any value of c, for that -8 is smaller, is a valid solution. our in other words, any value for c larger than -8 is a valid solution. so, yes, 2 is larger than -8, so it is a solution.
Answer:
2/3 , 13/18, 7/9 , 5/6 (least to greatest order)
Step-by-step explanation:
1. You need to convert all the fractions into decimal form .
2. 7/9.00 = 0.78 (rounded)
3. 13/18.00 = 0.72
4. 5/6.00 = 0.83
5 . 2/3.00= 0.67 (rounded)
