Answer:

x + 2y = -4

Step-by-step explanation:

A system of linear equations has one solution when the graphs intersect at one point.

Rewrite y = (1/2)x + 2 into the same format as the possible solutions and compare:

y = (1/2)x + 2

multiply both sides by 2: 2y = x + 4

Subtract 2y from both sides: 0 = x - 2y + 4

Subtract -4 from both sides: -4 = x - 2y

⇒ x - 2y = -4

Compare:

2x - 4y = 4 ⇒ parallel
x + 2y = -4 ⇒ intersects at one point
x - 2y = -4 ⇒ equivalent
x - 2y = 4 ⇒ parallel

Which of the following best describes the solution to the system of equations below?

OverLord2011 [107]

Answer: OPTION A

Step-by-step explanation:

The equation of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b the y-intercept.

Solve for y from each equation:

$\left \{ {{5y=-4x+7} \atop {10y=-8x+14}} \right.\\\\\left \{ {{y=\frac{-4}{5}x+\frac{7}{5}} \atop {y=\frac{-8}{10}x+\frac{14}{10}}} \right.\\\\\left \{ {{y=\frac{-4}{5}x+\frac{7}{5}} \atop {y=\frac{-4}{5}x+\frac{7}{5}}} \right.$

As you can see the slope and the y-intercept of each equation are equal, this means that both are the exact same line. Therefore, you can conclude that the system has infinitely many solutions.

REALLY NEED HELP

IgorLugansk [536]

You can compare information on up to three different Loan Options at one time. When entering information into the calculator, please use the following guidelines:
Interest Rate is the APR from the loan rate chart. If the loan rate is 6.5% you would type 6.5 into the Interest Rate blank
# of Payments is the number of monthly payments you will make to pay off the loan. For example, if the approximate term of the loan is 4 years or 48 months, you would enter 48 in the # of Payments blank
Principal is the amount of money you want to borrow. If you want to borrow $7,500 you would enter 7500 in the Principal blank
Monthly Payment is the estimated amount of money you will need to pay each month to pay off the loan
