Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs = 
= 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51
Answer:
<h2>
y-9 = 17(x+7)</h2>
Step-by-step explanation:
Given the points (-8, -8) and (-7, 9), the general form of equation of the line passing through this point is expressed as y-y1 = m(x-x1) where;
m = slope or gradient and (x1, y1) is the point
m = Δy/Δx = y₂-y₁/x₂-x₁
m = 9-(-8)/-7-(-8)
m = 17/1
m = 17
The slope of the line is 17.
The point-slope equation of the line through the point (-7, 9) is expressed as
y-9 = 17(x-(-7))
y-9 = 17(x+7)
Answer:
B. Rational functions
Step-by-step explanation:
The partial fraction decomposition is used for functions there are described by fractions, and for which the substitution method is not possible. These are rational functions, in which both the numerator and the denominator are polynomials.
So the correct answer is:
B. Rational functions
