PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000
PART B:
For the price of 3.50 we have:
y = -1000 * (3.5) +9000
y = 5500
Answer:
Option B Yes by AAA
Step-by-step explanation:
we know that
If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
so

substitute the values and verify

simplify
-------> is true
therefore
The triangles are similar by AAA------> the three angles are congruent
Answer:
4
Step-by-step explanation:
since it's all addition, we can remove the parentheses

Now we combine like terms


We subtract both sides by 12 to get,

now we divide both sides by 11


-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
