The answer is option A.
The $50 initial membership fee represents the y-intercept (b), while the $20 monthly membership fee represents the slope (m) of the equation.
Option B:
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Solution:
Given expression:
To find the equivalent expression for the given expression.
Apply absolute value rule:
<em>If |x| ≤ m then -m ≤ x ≤ m.</em>
⇒ -5 ≤ a ≤ 5
⇒ -5 ≤ a and a ≤ 5
Switch the sides, we get
⇒ a ≥ -5 and a ≤ 5
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Option B is the correct answer.
Y=2x+0.5
4.5=2x+0.5
4.5-0.5=4
4=2x
4÷2=2
x=2
so
The slope is -3/4 for your question
