Solve by factoring 15x^2 - 25x =0

Mathematics
1 answer:
dalvyx [7]3 years ago
5 0

Answer:

Answer below!

Step-by-step explanation:

15x^{2} -25x=0\\5x(3x-5)=0\\                           \frac{5x}{5}=\frac{0}{5} ;x=0

3x - 5 = 0

Add 5 to both sides;

3x = 5

Divide both sides by 3;

x=\frac{5}{3}

The center of a circle is at the origin. and endpoint of a diameter of the circle is at (-3, -4. how long is the diameter of the
Aleks [24]
The diameter is 10:

To do this we must use the distance formula:

Distance =√(x2−x1)^2+(y2−y1)^2

So, if we substitute in our values for the origin and endpoint (origin is 1 values, endpoint is 2)

D=✓(-4-0)^2+(-3-0)^2

Simplified, this is

D=✓16+9
D=✓25
D=5

so, the distance from the center of the crcle to the endpoint is 5 (making the radius)

multiply by two, and the diameter of the circle is 10 :)
