Answer:
5(5x+3)
Step-by-step explanation:
25x=5*5x
15=5*3
5*5x+5*3
Factor out the Common 5
5(5x+3)
Answer:
Step-by-step explanation:
What are the center and radius of the circle described by the equation x2 + y2 + 6x + 10y + 18 = 0?
Center (3.5); Radius 4
Center (-3,-5); Radius 4
O Center (3,5); Radius 16
O Center (3.5); Radius 10
x² + y²+ 6x + 10y + 18 = 0
x² + 6x + y² + 10y = -18
x² + 6x + 9 + y² + 10y + 25 = -18 + 6 + 9
x² + 3x + 3x + 9 + y² + 5y + 5y + 25 = -3
Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
What value of b will cause the system to have an infinite number of solutions?
y = 6x – b
–3x + 1/2y = –3
we have
----->equation A
-----> equation B
we know that
If the system has infinite number of solutions then, the equation A must be equal to the equation B
so
isolate variable y in the equation B

Multiply by
both sides

-------> new equation B
To find out the value of b, equate equation A and equation B


a straight line = 180 degrees
so the missing angle is 180 - 130 = 50 degrees
it is b -30 plz give me brainlist
