The answer is A because 2 multiplied by 9 is 18
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:
Option 4
Step-by-step explanation:
Given:
Sinθ =
Since, cos2θ = 1 - 2sin²θ
cos2θ =
cos2θ = 1 -
cos2θ =
cos2θ =
Therefore, Option 4 will be the answer.
