Answer:
The product of x and y would be (8)(-1) = -8. by adding the two equations you get 2x = 16 so x = 8. then y = 7 - x = -1. Therefore xy = -8.
Answer: The area of the notebook that the sticker covers is 128 cm^2
Step-by-step explanation:
The equation for the area of a rectangle should be:

-The height of the stickers measures 16 cm:

-So, if the base is half as long as the height, you divide it by 2:

-Then, you substitute it:
· 
-Result:

EXPLANATION
The perimeter of triangle OQR is the sum of the distance around the triangle.
Thus,

We can observe that two of the angles are equal.
The angles that are equal measures 62° each.
Therefore triangle OQR is an isosceles triangle. This means that

Hence,

units.

Answer:
yield of this new bond is 4.42%
Step-by-step explanation:
given data
bond = $5000
coupon rate = 4.6%
purchased bond = $5195
to find out
yield of this new bond
solution
We get here first amount paid to the bond holder
amount paid = 4.6% × $5000
amount paid = $230
and
so Tim earned $230 on a bond that cost her $5195
so yield of this new bond =
yield of this new bond = 4.42 %
