The initial expression is:

So we can solve for r so:
Answer:
1.2
Step-by-step explanation:
Gradient = y2-y1/x2-x1
Coordinates = (4,6), (-16,-18)
-18 - 6/-16 - 4
-24/ -20
= 1.2
Hope it helps.
Answer:
<h2><em><u>-x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em></h2>
Step-by-step explanation:
<em><u>If</u></em><em><u>,</u></em>
x = -2
<em><u>Then</u></em><em><u>,</u></em>
-x = -(-2)
=> <em><u>-x = 2 (Ans)</u></em>
1) -149, -1; -148, -2; -147, -3
2) No, according to the commutative property of addition, it does not matter the order they are put in.
Hope this helps!
You'd do $0.50 × 11 = $5.50 which is the total cost for the rides, and then you'd add $6 to make $11.50 which is the total amount you spent.
