Answer:
I'm not sure bu I think the answer is 8 × x × 7 = 2
Math:
7 dogs, 3 cats, 5 birds. In total, there are 15 animals all together.
So ignore the 3 and 5 those are in there to throw you off. To get the percentage, you do 7/15
So you'd get 0.4666667
Answer: 0.467
Rounded Answer: 0.47 (Or 47% B)
Step-by-step explanation:
a general line equation is
y = ax + b
the original line is
y = 3/5 x + 10
the factor of x is always the slope (inclination of the line).
it is "y change/x change".
the slope of a perpendicular line (angle of 90°) is turning the slope of the original line upside-down and flips the sign.
so, it is -5/3.
we use the point information to get the right "b" for our new line :
-5 = -5/3 × 15 + b
-5 = -5×5 + b
-5 = -25 + b
b = 20
so, the perpendicular line equation going through (15, -5) is
y = -5/3 x + 20
