Answer: 25

Step-by-step explanation:

To figure out the mystery number, the biggest clue we have is the fact that the number is a double digit and the 2 integers add up to 7. We can list out the possible ways to get a sum of 7. Then we can see which is the mystery number.

0+7

1+6

2+5

3+4

With these pairs, we can automatically eliminate 0+7 because 70 is greater than 30. We can also eliminate 3+4 because 34 is even, not odd. When you flip it to 4+3, it is odd, but it is greater than 30. We can also eliminate 1+6 because 16 is even and 61 is greater than 30. Our answer is 25. 2+5=7 and 25 is odd that is less than 30.

ΔCAR has coordinates C (2, 4), A (1, 1), and R (3, 0). A translation maps point C to C' (3, 2). Find the coordinates of A' and R

shutvik [7]

Answer:

$A'= (2,-1)$ and $R'=(4,-2)$ under this translation.

Step-by-step explanation:

A translation in $R^{2}$ is a mapping T from $R^{2}$ to $R^{2}$ defined by $T(x,y) = (x + v_1,y+v_2)$ , where $v=(v_1,v_2)$ is a fixed vector in $R^{2}$ .

From the problem we know that $T(2,4)=(3,2)$ , so we need to find the values $v_1$ and $v_2$ such that $T(2,4) = (2 + v_1,4+v_2)=(3,2)$ , so $3=2 + v_1$ and $4+v_2=2$ , thus $v_1=1$ and $v_2=2$ .
