Answer:
Step-by-step explanation:
To find the inverse of a function, begin by switching the places of the 'y' and 'x' variables. Instead of f(x), we will substitute in 'y' for this purpose.
Substitute in 'y':
Swap the 'y' and 'x':
Square both sides:
Simplify:
**Keep in mind, when finding the inverse of a square root function, there is always going to be a restricted domain. In this instance, the restricted domain is
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>
Answer:
He traveled 612 miles in total.
Step-by-step explanation:
You simply multiply the mph he was going to how long he traveled for. This gives us 72x8.5 equaling 612.
Answer:
I belive x=4.9
Step-by-step explanation:
(i) XYZ = 180 - 64
= 116 degrees
Opposite angles in a cyclic quadrilateral add up to 180 degrees
(ii) YXZ = 23 degrees
Alternate angles in a segment are the same
(iii) OXZ = 26
XOZ = 64 x 2
= 128 degrees
The the angle at the centre is double the angle at the circumference.
180 - 128 = 52
OXZ = 52/2
= 26
Triangle OZX is an isosceles triangle
