Answer:
we have
C = 1.5d
or
d=C/1.5
Step-by-step explanation:
when d is 12
C=1.5×12=18
when c=15
d=15/1.5=10
Solving this problem needs the distance formula of point to a line.
The formula is:
distance = | a x + b y + c | / √ (a^2 + b^2)
So we are given the equation: y = 2 x + 4
Rewriting this would be: y – 2 x – 4 = 0 -> a = -2, b = 1, c = -4
We are also given the points:
(-4, 11) = (x, y)
Plugging it in the distance formula at points (x, y):
distance = | -2 * -4 + 1 * 11 + -4 | / √ [(- 2)^2 + (1)^2]
= 15 / √ (5)
= 6.7
So the tree is approximately 6.7 feet away from the zip line.
Answer:
7
Step-by-step explanation:
Remove parentheses.

Add −8 and 4.5.

Subtract 8.25 from 6.25.

Multiply 4 by −3.5.

Divide −14 by −2.
= 7
The answer is A because all three of them have the same amount of coins
