If the graphs of a system of linear equations are the same line, how many solutions does the system have?
inn [45]

Answer:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

What does this mean? and how can y =x or what us the answer to y=x I need help
Readme [11.4K]
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.

Using a minimum of two sentences, describe how to write the function, f(x) = (x + 2)^2 - 3, in standard form.
Lostsunrise [7]
First, simplify the (x+2)(x+2) with FOIL:
f(x)=(x^{2} +2x+2x+4)-3
Combine like terms
f(x)=x^{2} +4x+1
Then you have standard form.

Hope that helps.

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet. Approx
Hunter-Best [27]

Answer:

a) 50.24 ft²

b) 150.72 ft²

Step-by-step explanation:

Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.

The distance across a circle is also called a diameter, Hence,

D = Diameter = 8 ft

The Area of a circle = πr²

r = Diameter/2 = 8ft/2 = 4ft

π = 3.14

Hence,

The Area of the circle = π × (4 ft)²

= 50.24 ft²

a) Approximately the amount of wall the circle will cover is 50.24 ft².

b) How much area will he cover if he painted a circle on three walls?

This is calculated as:

1 wall = 50.24 ft²

3 walls = x

Cross Multiply

x = 3 × 50.24 ft²

x = 150.72 ft²

Solve for x: two thirds(x − 2) = 4x.
Sveta_85 [38]

Answer:

x =  - 0.4

Step-by-step explanation:

\frac{2}{3} (x - 2) = 4x

Expand with the distributive rule:

\frac{2}{3} x -  \frac{2}{3}  \times 2 = 4x

\frac{2}{3} x -  \frac{4}{3}  = 4x

Add 4/3 to both sides:

\frac{2}{3} x = 4x +  \frac{4}{3}

Subtract 4x from both sides

- \frac{10}{3} x =  \frac{4}{3}

- 10x = 4

x =  - 0.4
