Yes, Bobby will have enough money if he saves for 9 weeks. You can find this through either substituting w for 9 in the equation, or solving the equation itself.
Substituting:
Substitute w for 9.
Simplify.
Solve.
255 is greater than 250, so yes, he will have enough money saved.
Solving the equation:
Original Equation
Subtract 30 from both sides.
Divide both sides by 25.
The number of weeks he needs is 8.8. When rounding it up, you get 9.
The length of the shortest side of the hexagon is; 41.833 inches
<h3>How to find the perimeter of a Polygon?</h3>
Let the length of the shortest side of the hexagon be x. Now, a hexagon has six sides and if the next side is 10 inches longer than the previous side, then the length of the six sides are;
x, x + 10, x + 20, x + 30, x + 40, x + 50
Perimeter is given as 401 inches. Thus;
x + x + 10 + x + 20 + x + 30 + x + 40 + x + 50 = 401
6x + 150 = 401
6x = 401 - 150
6x = 251
x = 251/6
x = 41.833 inches

Answer:
FOr the first one you can do:
y= -x +4
y= -x+2
y = -x
y= -x-2
y = x-4
Step-by-step explanation:
I'll do the second one in a different answer use these for now.
1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of 
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
