Y=65+40x, i believe this is it im not to sure
Answer:
$1.3
Step-by-step explanation:
(11.75 - 5.25) / 5 = 1.3
Answer:
Part 1) The equation for the monthly charges for Runfast is and for BA&D is
Part 2) The solution of the system of equations is the point (1.75.22)
Step-by-step explanation:
Let
x -----> the number of gig of data
y -----> the total monthly charges
we know that
<em>Runfast Company</em>
-----> equation A
<em>BA&D Company</em>
-----> equation B
Part 2) Use your mathematical skill to solve this system of equations using the substitution method
we have
-----> equation A
-----> equation B
Substitute equation B in equation A and solve for x
Find the value of y
so
The solution is the point (1.75.22)
That means
For the number of gig equal to 1.75 the monthly charge is equal to $22 in both company's
therefore
For a number of gigs less than 1.75 the company Runfast has the better pricing, while for a number of gigs greater than 1.75 the company BA&D has the better pricing

Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° = =
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b = ≈ 7.5 ( to the nearest tenth )
sin39° = =
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c = ≈ 28.0 ( to the nearest tenth )
