Answer: w = -3/2u + 2
Step-by-step explanation: The independent variable, normally x, is not impacted by other variables. The problem is asking you to put the equation in w= form. W is the dependent variable while u is the independent variable (we’re used to seeing y= form, where x is independent and y is dependent. This is the same thing with different letters).
-12u + 13 = 8w - 3
-12u + 16 = 8w (add 3 to both sides)
(-12u + 16)/8 = w (divide both sides by 8)
-12/8u + 16/8 = w
-3/2u + 2 = w (simplify)
So to start off you subtract y2 - y1/x2 - x1. This should look like -5 - -1/ -4 - -4. Now you do the math and you should get -4/0. Therefore the slope is undefined.

Answer: 4) y = -1/3x² + 2x - 1
Step-by-step explanation:
Given :
y = 
+ 2
Expanding (x-3)² will give :
- 6x + 9
substituting into the function , we have :
y = 
- 6x + 9 ) + 2
Expanding , we have
y = 
+ 2x - 3 + 2
y = 
+ 2x - 1
Answer:
Sabrina bought 6 yellow bananas and 3 green bananas
Step-by-step explanation:
Let
Green bananas = x
Yellow bananas = y
Green bananas = $14.00
Yellow bananas = $12.00
Total cost = $114.00
x + y = 9 (1)
14x + 12y = 114 (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
14(9 - y) + 12y = 114
126 - 14y + 12y = 114
- 14y + 12y = 114 - 126
-2y = -12
Divide both sides by -2
y = -12 / -2
= 6
y = 6
Substitute y = 6 into (1)
x + y = 9
x + 6 = 9
x = 9 - 6
= 3
x = 3
