Lisa invests $4,000 in two types of bonds, bond A and bond B. Bond A offers a 10% return, and bond B offers a 6% return. Lisa invested in each bond in x and y amounts. To solve the problem using two equation: x +y =4000

                0.10x + 0.06y = 340

Solving the equation lisa invested $2500 in 10% rate and $1500 in 6% rate.

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.

If f(x)=3^x, then f(-2)= ?<br> A.1/9<br> B.9<br> C.-6<br> D.-9
statuscvo [17]
You start by plugging in x=-2 into f(x)
f(-2) = 3^-2
Which gives you
f(-2) = 1/3^2 since negative exponents change the number to a dividend.
Then you square the 3
f(-2) = 1/9 or .111 repeating
