Mathematics
1 answer:
Bogdan [553]3 years ago
8 0

Answer:

3

Step-by-step explanation:

Set the sides equal to one another because it's an equalteral triangle.

5 - 2x = -4x + 9

Add 4x to the left side and subtract 5 getting 2x = 4 meaning x=2

Plug X into the equation for the sides 5 - 2(2)=1

1+1+1= 3 because there are 3 sides that equal 1.

What is the equation of the circle with center (2, –5) that passes through the point (–2, 10)?
Travka [436]
The standard equation of a circle is

(x-h)^2 + (y-k)^2 = r^2

where the center is at point (h,k)

From the statement of the problem, it is already established that h = 2 and k = -5. What we have to determine is the value of r. This could be calculated by calculating the distance between the center and point (-2,10). The formula would be

r = square root [(x1-x2)^2 + (y1-y2)^2)]
r = square root [(2--2)^2 + (-5-10)^2)]
r = square root (241)
r^2 = 241

Thus, the equation of the circle is

(x-2)^{2} + (y+5)^{2} =241

3x + 4y = 24<br> 6x + 8y = 24 using process of elimination
Lelechka [254]

Answer:

false

Step-by-step explanation:

3x+4y=24 multiplied by 2 equals: 6x+8y=48

if you subtract 6x+8y=24 from 6x+8y=48, you get 0=24, which is not true. Therefore the statement is false.
