Answer:
x=3 and y=−2
Step-by-step explanation:
Multiply the first equation by 4,and multiply the second equation by 3.
4(2x−3y=12)
3(3x+4y=1)
Becomes:
8x−12y=48
9x+12y=3
Add these equations to eliminate y:
17x=51
Then solve17x=51for x:
17x=51
17x
17
=
51
17
(Divide both sides by 17)
x=3
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
2x−3y=12
Substitute3forxin2x−3y=12:
(2)(3)−3y=12
−3y+6=12(Simplify both sides of the equation)
−3y+6+−6=12+−6(Add -6 to both sides)
−3y=6
−3y
−3
=
6
−3
(Divide both sides by -3)
y=−2
Answer:F(x)=3
Step-by-step explanation:
KK!
The two plans charge the same amount in 11 months.
The plan I would recommend if the plans are contracted for two months is the Fidoll plan.
<h3> When will the two plans charge the same amount?</h3>
The equation that represents the amount that would be paid by Kayla if she buys the phone from Rongers is : $127x
Where x represents the number of months
The equation that represents the amount that would be paid by Kayla if she buys the phone from Fidoll is : $363 + $94x
Where x represents the number of months
The two above equations would be equal when the plan charge the same amount: $363 + $94x = $127x
Combine similar terms
$363 = $127x - $94x
Add similar terms
$363 = $33x
Divide both sides by 33
x = 11 months
<h3>Which plan would be recommended if the plan is for 2 years?</h3>
Rongers: $127(24) = $3,048
Fidoll = $363 + $94(24) = $2619
I would recommend the Fidoll plan
