Answer: y=7+2x
Step-by-step explanation: Divide 5 by all. 5y/5=35/5 +10x/5.
Answer:
C
Step-by-step explanation:
A is right, D is right because they are on the outside and on different sides, B is actually right since they are on the inside and on different sides, so that leaves c, so this has to be the wrong one because they are not both interior since 5 is on the outside and 6 is inside even if they are both on the same side
housing: 900/4500 = 0.2 = 20%
transportation: 650 / 4500 = 0.14 = 14%
utilities: 120/4500 = 0.026 = 2.6% ( round to 3% maybe)
food: 475/4500 = 0.105 = 10.5% (round to 11% maybe)
savings: 1600 / 4500 = 0.355 = 35.5% (round to 36% maybe)
Student Loan: 270 / 4500 = 0.06 = 6%
Other expenses: 485 / 4500 = 0.107 = 10.7% (round to 11% maybe)
You didn't say if they needed to be rounded so I gave you the options on the ones that may need it.
the answer is B these are the steps of getting your answer
Note that the 2nd equation can be re-written as y=8x-10.
According to the second equation, y=x^2+12x+30.
Equate these two equations to eliminate y:
8x-10 = x^2+12x+30
Group all terms together on the right side. To do this, add -8x+10 to both sides. Then 0 = x^2 +4x +40. You must now solve this quadratic equation for x, if possible. I found that this equation has NO REAL SOLUTIONS, so we must conclude that the given system of equations has NO REAL SOLUTIONS.
If you have a graphing calculator, please graph 8x-10 and x^2+12x+30 on the same screen. You will see two separate graphs that do NOT intersect. This is another way in which to see / conclude that there is NO REAL SOLUTION to this system of equations.
