Answer:
y = x - 11
Step-by-step explanation:
Slope-intercept form: y = mx + b
<u>Step 1: Subtract x from both sides</u>
x - y - x = 11 - x
-y = 11 - x
<u>Step 2: Multiply both sides by -1</u>
-y * -1 = (11 - x) * -1
<em>y = x - 11</em>

Answer: y = x - 11
Given
the lengths of the 3 sides of a triangle
Find
the angle opposite the longest side
Solution
Strategy: make use of the Law of Cosines, which relates an angle and the three sides of a triangle.
... a² = b² + c² -2bc·cos(A)
... cos(A) = (b² + c² - a²)/(2bc) . . . . . . . solve for cos(A)
... A = arccos((b² + c² - a²)/(2bc))
Fill in the given values and evaluate.
... A = arccos((55² + 50² - 90²)/(2·55·50)) = arccos(-2575/5500)
... A ≈ 117.9°
Volume refers to the capacity of something, how much can something hold.
Area refers to, how much is needed to cover something.
Answer is G
Explanation: Since X= 5, we’ll plug in X to anywhere it’s in the inequality with the number 5. So
5-2<7
5-2= 3
3<7
3 is in fact less than 7
Answer:
58
Step-by-step explanation:
5^2 = 5 x 5 = 25
3 x 7 = 21
25 + 21 + 12
