Answer:
i think it is B
Step-by-step explanation:
By the Pythagorean Theorem, the length of x is
a^2 + b^2 = c^2 Pythagorean Theorem
6^2 + b^2 = 10^2 Substitute known variables
6^2 + b^2 - 10^2 = 0 Subtract 10^2 from each side
6^2 - 10^2 = b^2 Subtract b^2 from each side
√6^2-10^2 = √b^2 Take square root of each side
8 = b Simplify
So, the length of x is 8. I hope this helps!
Answer:
B. 3.79797979797979
Step-by-step explanation:
Your original inequality is
.. w -2 ≤ 8
The additive property of equality applies to inequalities as well as to equations. You use the additive property of equality to solve this. Add 2 to both sides.
.. w -2 +2 ≤ 8 +2
The purpose of adding 2 is to cancel the effect of subtracting 2. That is, -2+2=0, and w+0 = w.
.. w ≤ 10
The correct selection would be B.
To find this, just plug the numbers into the expressions.
5x = y
5(2) = 7
10 = 7
So it can't be A.
x + 2 = y
2 + 2 = 7
4 = 7
x + 4 = y
2 + 4 = 7
6 = 7
2x + 3 = y
2(2) + 3 = 7
7 = 7
The correct answer is
D. 2x + 3
