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 invests $x in bond a and $y in bond b. her total return on the investment is $340. the system of linear equations defining the situation iswhat . the amount lisa invested at the rate of 10% is what , and the amount she invested at the rate of 6% is what

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.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

b. x + 1
