Answer:
Step-by-step explanation:
Height of the triangle = 3 units
Height is always the perpendicular length.
A) Interest = principal * rate * time
I = (800)(0.05)(3) = $120
b) $800 + $120 = $920 after the three years. $920 * (1 - 0.02) = $901.60.
Answer:
240 square units
Step-by-step explanation:
rectangle= 20x10=200
triangle= 1/2(4)(20)=40
200+40=240
The point that is a solution to the system of inequalities is (5, 0)
<h3>How to determine the points on the solution?</h3>
The system of inequalities is given as:
y ≤ 2x + 2
y ≥ -5x + 4
Next, we test the given options.
From the list of options, we have
(x, y) = (5, 0)
Substitute (x, y) = (5, 0) in y ≤ 2x + 2 and y ≥ -5x + 4
y ≤ 2x + 2
0 ≤ 2 * 5 + 2
0 ≤ 12 -- this is true
y ≥ -5x + 4
0 ≥ -5 * 5 + 4
0 ≥ -21 -- this is true
Since both results are true, then it means that the point that is a solution to the system of inequalities is (5, 0)

<u>Complete question</u>
Which point is a solution to the system of inequalities graphed here? y ≤ 2x + 2
y ≥ -5x + 4
A. (1,6)
B. (-6,0)
C. (0,5)
D. (5,0)
First set up a system of equations and solve.
4x+y=10
x+3y=8
In order to have one variable cancel out, I will multiply the top by -3.
-12x-3y=-30
x+3y=8
____________
-11x=-22
x=2
Then plug the x value into one of the original equations.
(2)+3y=8
3y=6
y=2
Now plug both into the final equation:
5(2)+8(2)/3
(10+16)/3
26/3
8.667 is the answer or 26/3.
