When you isolate the y on one side, the slope intercept form of the line is

Two plot point examples would be (0, - 3) (which is the y intercept) and (1, -7)
Let a and b be odd number.
Because they are odd, by definition:
a = 2n + 1
b = 2m + 1
If we add them up:
a + b = 2n + 1 + 2m + 1
= 2n + 2m + 2
= 2(n + m + 2)
= 2k where k = n + m + 2
therefore a + b is always even.
Answer:
Step-by-step explanation:
<u>Given function</u>
- V(x) = 275000(1.09)^(2/3x)
<u>Every year the value is changing at the rate:</u>
- (1.09)^(2/3) = 1.059 ≈ 1.06
The rate of 1.06 is equivalent of 6% increase per year
Answer:
7
Step-by-step explanation:
the altitude creates two congruent 30-60-90° triangles
the ratio of the sides in a 30-60-90°, respectively, are 1 :
: 2
therefore we can set up a proportion to find the side length:
let 'x' = side length of equilateral Δ
/ 1 = 21 / x
cross-multiply:
x = 21
x = 21 / 
rationalize the denominator by multiplying numerator and denominator by 
21
/
·
= 21
/ 3 or 7
