Can yall help me pls

The best way to solve these by graphing instead of substitution or elimination, is to use a free website called Desmos. Input the 2 equations and find the intersection.

a) 2 lines intersecting at (4,2)

Step-by-step explanation:

When u graph y=2x, you start at (0,0) and go up two and over one to the right

When you graph y= - 1/2 + 5 you start at 5 and go down one and over two to the right

You can see the intersect

1. 34

2. 268

3. x=14.4

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
