The answer: c. 24
1/2 x 24 = 12
Answer:
(x+1)^2 + (y+1)^2 = 49
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- -1)^2 + (y- -1)^2 = 7^2
Simplifying
(x+1)^2 + (y+1)^2 = 49
I can only give possible combinations of the ages. This is because only the product is given. Had the sum of all ages been given, possible combinations would boil down into 1 combination.
3 kids with a youngest. This means that the ages are not the same.
We do prime factorization to get the age combination.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72
Possible combination with no repeating number.
1 x 8 x 9 = 72
2 x 4 x 9 = 72
4 x 6 x 3 = 72
1 x 6 x 12 = 72
Answer:
Step-by-step explanation:
D. No solution
This is simply because -3x-6 cannot equal -3x-7 because -6 and -7 are different numbers therefore x is a false statement.
In math, an isometry is a congruent transformation in which the distance (or length) and the angle is preserved or remains the same even after the transformation.
The transformation can be translation, rotation, reflection, etc.
Let us not use this definition of isometry to answer our question, one at a time.
(I) In here, as we can see the distances 10 and 5 and the angle 43 degrees has been preserved. So, <u>this is an isometry.</u>
(II) In here, distances have been halved, so this is<u> not an isometry</u>, even though the angles have been preserved.
(III) In here, the corresponding distances and the angles have been preserved. So, <u>this is an isometry.</u>
