Answer:
y=-x-2
Step-by-step explanation:
The line passes through the points -2,0 and 0,-2. The line is slanted towards the left so the line has a negative slope.
equation of line with negative slope: y=mx+b
using the rise over run tactic: 2/2= 1
y=-x+b
the y intercept is 0,-2
y=-x-2
Answer:
<em>84 centimeters of the width of the item in reality</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
1 = 14 ⇒ x - width of item in reality (cm)
6 x
<em>2. Now let us cross multiply, and solve through simple algebra:</em>
14 * 6 = x,
<em>x = 84 centimeters of the width of the item in reality</em>
Answer:
8 laps
Step-by-step explanation:
Assuming in the equation given than n represents the number of laps run and t represents the time in minutes, when we plug in 16 in for t and simplify we get:
n=5/10*16
n=1/2*16 (Simplify the fraction by dividing top and bottom by 5)
n=16/2 (Multiply the fractions together by writing 16 as 16/1 and multiplying straight across)
n=8
12*6=72 radius of 3, 3*3.14=9.42 so 72+9.42=81.42 :)
