Given two points: A(x₁,y₁) and B(x₂,y₂), the slope of the line that passes through these points will be:
<span>m=(y₂-y₁)/(x₂-x₁)
We take 2 points of this line:
For example:
(0,3) and (5,3).
We compute the slope:
m=(3-3)/(5-0)=0/5=0
Answer: B) 0</span>
Answer:1/2 inch
Step-by-step explanation: the longest is one inch. The shortest is half an inch. 1-0.5=0.5, aka 1/2
Answer:
P = 0.09r²
Step-by-step explanation:
Price, p is proportional to the square of its radius, r
P = k*r²
a mirror with radius 20cm has a price of £36
P = k * r²
36 = k * 20²
36 = k * 400
36 = 400k
k = 36/400
k = 0.09
Substitute the value of k into the equation:
P = k * r²
P = 0.09 * r²
P = 0.09r²
Answer:
149*
Step-by-step explanation:
The interior of a triangle equals 180*
63 + 86 = 149
180 - 149 = 31 (the missing value of the triangle.)
The line is also equal to 180*
180 - 31 = 149*
I hope this helps! :)
