Answer:
y=13/3x-1
Step-by-step explanation:
k=(y2-y1) /(x2-x1)
A(0,-1) x1=0,y1=-1
B(3,12) x2=3, y2=12
k=(12-(-1))/(3-0)
k=(12+1)/3
k=13/3
y-y1=k(x-x1)
y-(-1)=13/3(x-0)
y+1=13/3*x
y=13/3*x-1
Answer:
27/20
Step-by-step explanation:
The absolute value of any expression is always positive or zero
3/5 + 3/4
Add the fractions
27/20
Solution
27/20
Alternate form
1 7/20, 1.35
The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry
Answer:
a) <em>"K" is proportional Constant K= 0.0833</em>
<em>b) The value of b = 99.639</em>
Step-by-step explanation:
<u><em>Explanation</em></u> :-
Given 'a' is directly proportional to 'b'
a ∝ b
<em> a = k b ....(i)</em>
<em>where "K" is proportional Constant</em>
<u><em>Case(i)</em></u><em>:-</em>
<em>when a =6 and b=72</em>
<em> a = k b </em>
<em> ⇒ 6 = k (72)</em>
<em> ⇒ </em>
<em> </em>
<u><em>Case(ii)</em></u><em>:- </em>
<em> Given a = 8.3 </em>
<em> a = k b </em>
<em>⇒ 8.3 = 0.0833 ×b</em>
<em>⇒ </em>
<em></em>
<u><em>Final answer</em></u><em>:-</em>
a)<em>"K" is proportional Constant K= 0.0833</em>
<em>b) The value of b = 99.639</em>
