Answer:
3 and 1
Step-by-step explanation:
Answer:
Solution given:
A(a,b) lie in 6x-y =1
substituting value of A in equation ,we get
6a-b=1...................(1)
B(b,a) lie in 2x - 5y = 5
substituting value of B in equation ,we get
2b-5a=5
b=5(a+1)/2............(2)
substituting value of b in equation 1 ,we get
6a-5(a+1)/2=1
12a-5a-5=2
7a=2+5
a==1
substituting value of a in equation 1 ,we get
6×1-b=1
6-1=b
b=5
<u>so</u><u> </u><u>points</u><u> </u><u>are</u><u> </u><u>A</u><u>(</u><u>1</u><u>,</u><u>5</u><u>)</u><u> </u><u>and</u><u> </u><u>B</u><u>(</u><u>5</u><u>,</u><u>1</u><u>)</u>
we have
equation of line having two points
y-5=1-x
<u>x+y=6 is a required equation of line AB.</u>
if you add a negitive to a positive its like subtracting like 20 - (-30) (that would be -10) for your question its 0.6
Answer:
Step-by-step explanation:
That is correct.
P=4s=4(12)=48in
A=s^2=12^2=144in^2
Answer: After 18.05 minutes, the temperature of steel becomes 100 degrees.
Step-by-step explanation:
Since we have given that
Initial temperature = 2500
At t = 0,
we get that
After 2 minutes, the temperature of the steel is 1500 degrees.
so, it becomes,
So, We need to find the number of minutes when the temperature of steel would be 100 degrees.
So, it becomes,
Hence, after 18.05 minutes, the temperature of steel becomes 100 degrees.
