How do you graph a system of equation

Mathematics
1 answer:
Greeley [361]3 years ago
3 0
So, first your going to have to put it in y=mx+b
2x-2y=14
-2x -2x
-2y=-2x+14
now divide everything by -2
y=1x-7
and then do the same to the other equation.
x-y=2
-x. -x
-y=-x+2
now divide everything by -1
y=x-2

Then you just graph it. You plot the y-intercept on the y axis. and then I this case go up one over one and your get the points for each player equation.
y=1x-7. y- intercept:-7. slope:1 over 1
y=x-2. y-intercept:-2. slope:1 over 1

Area of circle with diameter of 1 m?
Elena-2011 [213]

Answer:

A = 0.785m²

B = 31400cm²

C = 7850cm²

D = 785,000mm²

Step-by-step explanation:

To solve this question, we'll have to find the area of a circle which is

Area of a circle = πr²

1. The diameter of the circle = 1m

Area of a circle = πr²

r = radius of the circle

π = 3.14

Radius = diameter / 2

Radius = 1 / 2 = 0.5m

Area = 3.14 × (0.5)²

Area = 3.14 × 0.25

Area = 0.785m²

2. Radius = 100cm

Area of a circle = πr²

Area = 3.14 × (100)²

Area = 3.14 × 10000

Area = 31400cm²

3. Diameter = 100cm

Area = πr²

Radius = diameter / 2

Radius = 100 / 2

Radius = 50cm

Area = πr²

Area = 3.14 × (50)²

Area = 3.14 × 2500

Area = 7850cm²

4. Radius = 500mm

Area = πr²

Area = 3.14 × (500)²

Area = 3.14 × 250,000

Area = 785,000mm²
