Answer:

1. y=5-2x

2. -y=5-2x

3. \frac{5 - x}{2}

Step-by-step explanation:

1. 2x+y=5

y=5-2x

2. 2x-y=5

-y=5-2x

3. x+2y=5

2y=5-x

\frac{5 - x}{2}

I need to know which ones are nonlinear or nonproportion
MrRissso [65]

Nonlinear means that -- the graph isn't exactly the line. It's basically a "curve" like parabola.

Non-proportional means that --- the graph doesn't start from the origin point or doesn't start at (0,0).

( A ) is both linear and proportion.

( B ) is proportion BUT NOT LINEAR (It's curved.)

( C ) is linear and proportion.

( D ) Is linear BUT NOT PROPORTION (Doesn't start at (0,0) )

So ( B ) and ( D )

Answer:

Choice B

Step-by-step explanation:

When two shapes are similar their sides are always going to be proportional. So here we will set up a proportion to solve this.

\frac{23}{40}=\frac{x}{17}

Now we cross multiply

391=40x

After we got an equation we solve it

x=9.775

Since we got a decimal we will have to round it to the place they instruct for us, on this one it is 9.8 cm so it is choice b.

A square pyramid and a cube have the same surface area don’t of each side of the base of the Square pyramid is 10 feet the width
o-na [289]

Answer:

The lateral height of the square pyramid is 5.8\ ft

Step-by-step explanation:

step 1

Find the surface area of the cube

The surface area of the cube is equal to

SA=6b^{2}

where

b is the length side of the cube

w have

b=6\ ft

substitute

SA=6(6^{2})=216\ ft^{2}

step 2

Find the lateral height of the square pyramid

we know that

the surface area of the square pyramid  is equal to

SA=B+4(\frac{1}{2}bh)

where

B is the area of the base

b is the base of the lateral triangle (base of the square)

h is the lateral height of the square pyramid

B=(10^{2})=100\ ft^{2}

SA=216\ ft^{2} -----> is the same surface that the cube

b=10\ ft

substitute the values and solve for h

216=100+4(\frac{1}{2}*(10)*h)

216-100=20h

h=116/20=5.8\ ft
