The solution set of 3x+5=x+2 is x=-1. This is because you want to get the variables on one side and the numbers on the other. you subtract x on both sides and subtract 5 on both sides. your equation then becomes 3x=-3. you then divide 3 on both sides and you get your answer of x=-1.
Answer:
D? i prob got it wrong
Step-by-step explanation:
Answer: Your equation would be y = x(12 - 2x)(8 - 2x).
The volume of a rectangular prism is V = LWH. The initial length and width are given as 12 and 8, however that makes the height 0.
If we cut out the corners, they would be the length of x. When we cut out the corners, we are subtract the length x from both ends of the length and width.
So now our measurements are:
Length: 12 - 2x
Side: 8 - 2x
Height: x
Multiply them altogether and you have your equation. Then, you can use your equation to find any measurements that you need.
Vertex = -b/2a = -(44)/2(-1) = -44/-2 = 22
To find the x-intercepts, set the function equal to 0 and solve for x
6•4=24 so he spent a total of $24
