Answer: Perimeter = 74
Step-by-step explanation:
Let
A-----> the point (0.25,1)
B-----> the point (0.50,1.75)
we know that
the equation that represents the linear function is the equation of a line
so
step 1
find the slope m with the points A and B
m=(y2-y1)/(x2-x1)-----> m=(1.75-1)/(0.50-0.25)---> m=0.75/0.25--> m=3
step 2
with m=3 and point A (0.25,1)
find the equation of a line
y-y1=m*(x-x1)-------> y-1=3*(x-0.25)----> y=3x-0.75+1----> y=3x+0.25
the answer isy=3x+0.25
see the attached figure
Total Area = 2( 32 x 79) + (26 x 42) = 6148 m²
Number of 4 m² = 6148 ÷ 4 = 1537
Answer: The zoo can have 1537 plants.
Let
x-------------> t<span>he width of each postcard
y-------------> the </span>the length of each postcard
we know that
A=12 in²
A=x*y-------> 12=x*y-------> equation 1
y=x+4-----> equation 2
<span>I substitute 2 in 1
</span>12=x*y----------> 12=x*[x+4]------> 12=x²+4x------> x²+4x-12=0
x²+4x-12=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=-6----> is not solution
x=2 in
y=x+4----> y=2+4-----> y=6 in
the answer isthe length of each postcard is 6 inthe width of each postcard is 2 in
A slope of zero means that the line is flat. In other words, change in "y" is equal to zero. Such an equation, using general representation of linear equation, is written as
y=mx+b but m=0
then, y=b
In the current scenario, b=-8
Therefore, the line equation is
y=-8
