Answer:
<h2>39 minutes</h2>
Step-by-step explanation:
In this problem we can see that there is a constant/flat rate charge of $4 on every first minute
we can model the cost for calls as
where x is the number of extra minutes spent
given that y = $13.75
We can simply substitute our given values into the equation 1 above and solve for x
Divide both sides by 0.25 to find x
Answer: the correct options are B, D and F
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
m = slope = rate of change
Looking at the equations given, the three that apply are
B) slope = 7
y intercept = 4
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
D) y = 9x + 1
slope = 9
y intercept = 1
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
F) y = 8x + 5
slope = 8
y intercept = 5
It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
Answer:
2
Step-by-step explanation:
x - 4y
where x = 26 and y = 6
x - 4y
26 - 4(6)
26 - 24

Answer:
Think its B. but if not it should be E.
Step-by-step explanation:
Answer:
The value of x is 4
Step-by-step explanation:
we know taht
<u>The intersecting chords theorem</u> states that the products of the lengths of the line segments on each chord are equal.
so
In this problem
solve for x
