Step-by-step explanation:
2A
x=1 y=3
x=4 y=0
y=mx+b
3=m+b
0=4m+b
3=-3m
m= -1
0=-4+b
b=4
y= -x +4
2B
x=2 y=0
x=0 y= -4
0=2m+b
-4=b
b=-4
0=2m-4
2m=4
m=2
y=2x-4
Meters are used to measure everything between the length of a ruler and the distance between things in a room. Most household objects such as tables, rooms, window frames, television screens, etc. would be measured in meters. Kilometers are used to measure long distances.
<em>a. 2√21 units</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<u><em>Area formula</em></u>
<em>A = π·r²</em>
<em>84π = πr²</em>
<em>r² = 84π/π</em>
<em>r² = 84</em>
<em>r² = 2²×3×7</em>
<em>r = √2²×3×7</em>
<em>r = 2√3×7</em>
<em>r = 2√21</em>
<em>Good luck !</em>
The range of f(x) = x + 5 is the set {0, 10}.
Therefore
x + 5 = 0 and x + 5 = 10
x = -5 and x = 5
<h3>The domain is {-5, 5}.</h3>
It’d be 12.458 , rounded to the nearest tenth makes it 12.5. Hopefully, I helped.
