Rearrange so x is the subject:-
(im assuning the f unction f(x) = (x + 2) / 7):-
f(x) = (x + 2)/7
7f(x) = x + 2
x = 7f(x) - 2
replace f(x) by x and x by another function
f = 7x - 2
Its D

Answer:
3/5
Step-by-step explanation: so far he has rolled 6/10 giving him a 6/10 probability, simplify that by 2 and you get 3/5.
Answer:
Thus, 2645 needs to be divided by 5 to become a perfect square. Thus, the required smallest whole number by which it should be divided so as to get a perfect square number is 5 and the square root is √529= 23.
Step-by-step explanation:
Yes, you are correct.
From the image, we can see 3 triangles, the large triangle and the two triangles that make the larger triangle.
All 3 of these triangles are similar since they're angle measurements are the same (can be proven by geometry).
We can gather the following information from the given information.
- The largest triangle (the one made up of two triangles) has a hypotenuse of 3+9=12, and a leg length of x. The hypotenuse to leg ratio is 12/x
- The second largest triangle has a hypotenuse length x and leg length 9. The hypotenuse to leg ratio is x/9
We know the hypotenuse to corresponding leg ratio must be equal since these two triangles are similar. Thus, we have the equation:
12/x = x/9
Using the cross product property gives us:
x² = 9 × 12
x² = 108
Taking the square root of both sides gives us:
x = √108
= 6 √3
Thus, your answer is correct. Great job!
