Replace the w with it’s value in the equation :
w⒳ = -2x + 1
-7 = -2x + 1
⓶
Then, you just simplify the right side in order to isolate the x (always take in consideration your priorities of operation) :
-7 = -2x + 1
÷-2 ÷-2
3.5 = x + 1
-1 -1
2.5 = x ☻
Answer: D) Yes, because each x value corresponds to exactly one y value
The table doesn't mention x, but usually x is in the left column. Since we don't have any repeated x values here, this means each input goes to exactly one output. So we have a function.
Visually if you plotted all the points, you'll see the graph passes the vertical line test.
Answer:
Step-by-step explanation:
g/2-9=-7
inverse operation:
g/2-9=-7
+9 +9
g/2=2
g/2=2*2
g = 4
Hello,
Answer is Dsince y=k(x-2)²-5 and if k=1 ==>D.
A box of donuts would cost: b = 3.84 + 0.18f
First, we have to find the total cost of the donuts.
12 x 0.32 = 3.84
Next, we need to determine the cost of the box. However, we don't know the surface area, just the cost per foot. We can multiply the number of square feet of the box by $0.18 to find the cost.
So our equation could be: b = 3.84 + 0.18f (where f is the surface area of the box in square feet)
