Yes, Graphs (depending on which one but I'm assuming your talking about coordinate grids) are proportional because they have on vertical and one horizontal line dividing them. They extend infinitely
Ur equation will be
citypop * (1.13^n)
where n is the number of years
a. 4/5 because
the equation to find slope is
y2-y1 divided by x2-x1
which is -5-(-1) divided by -2-3 which is -4/-5 which is 4/5.
Answer:
Side a = 35ft
Side b = 35ft
Side c = 20ft
Step-by-step explanation:
The formula for the perimeter of a triangle = Side a + Side b + Side c
In an isosceles triangle, 2 sides are equal to each other.
So, Side a = Side b
In the question, we are told that:
The two equal sides are each 5 ft less than twice the length of the third side.
Hence,
a = 2c - 5
b = 2c - 5
P = 90ft
P = a + b + c
90 = 2c - 5 + 2c - 5 + c
Collect like terms
90 = 5c - 10
90 + 10 = 5c
100 = 5c
c = 100/5
c = 20
The length of the third side = 20ft
a = 2c - 5
= 2 × 20 - 5
= 40 - 5
= 35 ft
b =2c - 5
= 2 × 20 - 5
= 40 - 5
= 35 ft
Therefore,
Side a = 35ft
Side b = 35ft
Side c = 20ft
