Answer:
$18500 at 6% and $28500 at 8%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then x+10000 is the amount invested at 8%. The total income from the two investments is the sum of the products of the amount invested and the interest rate:
x·6% +(x+10000)·8% = 3390
0.14x + 800 = 3390 . . . . . . . . collect terms
0.14x = 2590 . . . . . . . . . . . . . .subtract 800
2590/0.14 = x = 18500 . . . . . divide by the coefficient of x
Sue has invested $18500 at 6% and $28500 at 8%.
Answer:
reflect y = cos x over the x-axis
Step-by-step explanation:
When a function is reflected over the x-axis, the transformation is:
y = -f(x)
If it were reflected over the y-axis, the transformation would be:
y = f(-x)
Answer:
Graph 3
Step-by-step explanation:
EXAMPLE 6=60
4= 40
SINCE THERE IS NO NORMAL NUMBERS AND THERE ARE 10 , 20 ,30 ETC..
THE NORMAL NUMBERS TURN INTO 10 20 AND SO ON..

Answer:
Option A = 8t
Step-by-step explanation:
6t + 3t - 8t = t
6t + 3t = 9t
9t - 8t = t

<h3>How to prove congruent angles?</h3>
The image of the transversal line is attached.
1) We know that lines a and b are parallel and that line c is a transversal because that is given.
2) We can tell that angles 2 and 5 are congruent because vertical angles are congruent.
3) Angles 5 and 7 are congruent because corresponding angles by parallel lines cut by a transversal are congruent.
4) Therefore, angles 2 and 7 are congruent based on the transitive property.
