A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
A system of linear equations has one solution when the graphs intersect at a point...!
Answer:
35 dogs
Step-by-step explanation:
x ---> the number of dogs
y ---> the number of cats
The last week of January we have 20 cats and the ratio is the same
so
\frac{x}{y}=\frac{49}{28} ----> equation A
y=20 ---> equation B
substitute equation B in equation A
\frac{x}{20}=\frac{49}{28}
solve for x
x=\frac{49}{28}(20)=35 dogs
180-15=165
15x=165
165/15
x=11
First find g(2).
g(2) = (2+4)2 = 12
Because g(2) is 12, h(g(2)) = h(12).
h(12) = 2(12)-7 = 17
answer: 17
Answer:
94.985in^2
Step-by-step explanation:
Given data
Diameter= 11inches
Radius = 5.5 in i.e 11/2= 5.5inches
The Area of a circle is given as
Area= πr^2
Substitute
Area= 3.14*5.5^2
Area= 3.14*30.25
Area= 94.985 in^2
Hence the area is 94.985in^2
