3 mm would be the correct answer
Answer:
b a is the answer bea sue i don't know just looked it up
Step-by-step explanation:
Here, Translation factor: (x, y) → (x-4, y+5)
Coordinates of Image = B'(5, -6)
So, x-coordinate of point = x-4 = 5, x = 9
y-coordinate of point = y+5 = -6, y = -11
In short, Your Answer would be: Option B) (9, -11)
Hope this helps!
A total of $27,000 was invested; part of it at 10% and part of it at 12%. The total yield was $2990. How much was invested at each rate?
Let
x -----> amount invested at 10%
(27,000-x) -----> amount invested at 12%
we have that
0.10(x)+0.12(27,000-x)=2990 ------> equation A
solve for x
0.10x+3,240-0.12x=2,990
0.12x-0.10x=3,240-2,990
0.02x=250
x=$12,500
so
27,000-x=27,000-12,500=$14,500
therefore
amount invested at 10% ----> $12,500
amount invested at 12% -----> $14,500
