Let the amount invested at 4% be = x
Let the amount invested at 3% be = y
Given is:
or
.... (1)
As, total income for the two investments is $194, so equation is:
....(2)
Putting value of x from (1) in (2)




And x=5200-y

Hence, money invested at 4% is $3800 and money invested at 3% is $1400
Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
Area of a triangle: A = (1/2)BH
You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.
A = (1/2)(4)(4)
A = 8
** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

Answer:
B) 20
Step-by-step explanation:
Don't think to hard about the answer, all the numbers and text can be distracting.
Look at only the length of both Rachel 12 and Amos 16
Now use the Pythagorean theorem to find the unknown side in this right triangle.

Answer:
54 m^2
Step-by-step explanation:
Area of a kite is the two diagonals multiplied and then divided by 2.
3+3=6
12+6=18
18(6)=108
108/2=54
Therefore, 54 m^2
I hope this helped and have a good rest of your day!
