Each ordered pair is (x,y). Determine the coordinates by substitution.
for (15,y):
y=1/3 * 15 - 9
y=-4
for (x,-6):
-6=1/3x -9
1/3x=3
x=9
Answer:
(a) i believe it is $10
(b)I believe it is 98 people
Step-by-step explanation:
(a) we are trying to find "?" for this explanation. I came up with the equation 60=6 x ?. The 60 shows us the total amount of dollars that the 6 shares went down. We need to find the amount. of dollars that went down for 1 stock. So we divide 60 by 6. and get 10.
(b) we are trying to find "?" for this explanation. I came up with the equation
?=7 x 14. All you have to so is multiply 7 by 14 and you get 98.
Hope this helps :)

Answer:</h2>
The statement that best describes Imara's error is:
Option: D
D). She did not find the side lengths of the square with an area of 625.
<h2>
Step-by-step explanation:</h2>
Imara correctly did the previous calculation.
i.e. she correctly determined the area of square with side length 20 units (as 400 square units) and 15 units (i.e. 225 square units)
But when she sum the area of two squares then it won't give the length of hypotenuse it would give the area of a square.
Hence, the correct answer is:
Option: D
Answer:
<h2><u><em>
5</em></u></h2>
Step-by-step explanation:
X * 3^2 +2 = 47
X * 9 + 2 = 47
9X = 47 - 2
9x = 45
x = 45 : 9
X = 5
