Answer:
x = 100
Step-by-step explanation:
(100-40)/2
= 60/2
= 30
So it's 100

Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)
Slope = (-2)
38) (7 , 0) & (3 , 2)
39) The line is parallel to x-axis and so its slope is 0
Slope = 0
40) The line is parallel to y-axis and so its slope is undefined
Slope = undefined

Brian will need <em><u>8</u></em> book shelves to hold 304 books.
304/38 = 8
Hope this helps!
B. 60°
This is an equilateral triangle, so all angles should be equal. 180/3=60, so you’re answer is 60.
Each colection day: D
Number of tops collected on that day: N
D1=1; N1=2
D2=3; N2=8
1) Linear model
N-N1=m(D-D1)
m=(N2-N1)/(D2-D1)
m=(8-2)/(3-1)
m=(6)/(2)
m=3
N-N1=m(D-D1)
N-2=3(D-1)
N-2=3D-3
N-2+2=3D-3+2
N=3D-1
when D=6:
N=3(6)-1
N=18-1
N=17
<span>What is the number of tops collected on the sixth day based on the linear model?
</span>The number of tops collected on the sixth day based on the linear model is 17.
2) Exponential model
N=a(b)^D
D=D1=1→N=N1=2→2=a(b)^1→2=ab→ab=2 (1)
D=D2=3→N=N2=8→8=a(b)^3→8=a(b)^(1+2)
8=a(b)^1(b)^2→8=ab(b)^2 (2)
Replacing (1) in (2)
(2) 8=2(b)^2
Solving for b:
8/2=2(b)^2/2
4=(b)^2
sqrt(4)=sqrt( b)^2 )
2=b
b=2
Replacing b=2 in (1)
(1) ab=2
a(2)=2
Solving for a:
a(2)/2=2/2
a=1
Then, the exponential model is N=1(2)^D
N=(2)^D
When D=6:
N=(2)^6
N=64
<span>What is the number of tops collected on the sixth day based on the exponential model?
</span><span>The number of tops collected on the sixth day based on the exponential model is 64</span>
