Answer:
<em>(a). - 1 ; (b). y = - x + 11</em>
Step-by-step explanation:
(1, 10)
(6, 5)
<em>(a).</em> <em>m</em> = 
= 
= <em>- 1</em>
<em>(b).</em> y - 5 = - 1(x - 6)
<em>y = - x + 11</em>
Probability is about estimating or calculating how likely or 'probable' something is to happen.
When Javier writes 40 on both accounts they cost him the same amount of money so it should be 41.
Javier needs to write 41 checks for the second bank to beat better
Hey!
------------------------------------------------
First Equation:
2x + 3 = -7
2x + 3 - 3 = -7 - 3 (Subtract 7 to both sides)
2x = -10
2x/2 = -10/2 (Divide 2 to both sides)
x = -5
------------------------------------------------
Second Equation:
4.5x - 7 = 20
4.5x + (-7) + 7 = 20 + 7 (Add 7 to both sides)
4.5x = 27
4.5x/4.5 = 27/4.5 (Divide 4.5 to both sides)
x = 6
------------------------------------------------
Third Equation:
-3x + 7 = 28
-3x + 7 - 7 = 28 - 7 (Subtract 7 to both sides)
-3x/-3 = 21/-3 (Divide -3 to both sides)
x = -7
------------------------------------------------
Answers:
2x + 3 = -7 → x = -5
4.5x - 7 = 20 → x = 6
-3x + 7 = 28 → x = -7
------------------------------------------------
Hope This Helped! Good Luck!
