Answer:
The amount invested at 7% is $1,400 and the amount invested at 9% is $7,600
Step-by-step explanation:
Let
x ----> amount invested at 7%
(9,000-x) -----> amount invested at 9%
we know that
The interest earned by the amount invested at 7% plus the interest earned by the amount invested at 9% must be equal to $782
so
The linear equation that represent this problem is
solve for x
therefore
The amount invested at 7% is $1,400 and the amount invested at 9% is $7,600

The solutions to the system are -11.3 and 11.3.
The length of one leg of the sun shade is 11.3 feet.
Steps:
graph y=1/2 x^2
graph y=64
zoom out.
find the points of intersection.
done.
find y=mx+b for line parallel to AB.
The line that is parallel will have the same slope as line AB:
the slope of line AB is
m=(8-3)/(-10-2)
=5/-12
=-5/12
Since the line going through X is parallel the vertical distance of the new line to AB is the same for all values of the domain(x-axis).
at x=-5 the point X has the y value of 10 which is 4 more than the y value for AB based on the graph.
To find the intercept b of the line going through X that is parallel to AB we just add 4 to the intercept of AB, which is 4 so
4+4=8
