With 2 I think you minus 32 by 93 but idrk sorry
-(-7y + 12) = 7y - 12
u are distributing the -sign through the parenthesis...so u take the number outside of the parenthesis (and if it just a sign, the number is 1)...and u multiply it by everything in the parenthesis.
-1(-7y + 12) = -1 * -7y + (-1) * 12 = 7y + (-12) = 7y - 12
So if 7 is the middle x-value, you calculate how far it is from the given endpoint in order to determine how far it is from the other endpoint. So,
7 -5 =2, so the other endpoint must be 2 away from 7 in the opposite direction, 7+2=9
Then repeat with y,
3-1/2=5/2, therefore 1/2 - 5/2 = -4/2= -2
So the point is (9, -2)
Given:
In a right triangle at B,
To find:
The length of the sides b and c and angle B.
Explanation:
Using the trigonometric ratio,
Using the trigonometric ratio,
Using the angle sum property,
The angle B becomes,
Final answer:
The values are,
Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.
Solution
2.7 ≤ b + 5 Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b Write with the variable on the left.
b ≥ - 2.3 <<<< answer
