Answer:
first option
Step-by-step explanation:
Given 2 secants to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
PQ(RP) = PS(TP)
Answer:
The standard form of the equation is 2x + 5y = -1
Step-by-step explanation:
To find this equation in standard form, we first need to find the slope of the line. We can do that by using the slope formula with the two points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -3)/(-3 - 7)
m = 4/-10
m = -2/5
Now that we have the slope, we can use that along with the point in point-slope form
y - y1 = m(x - x1)
y - 1 = -2/5(x + 3)
Now that we have that, we can solve for the constant and rationalize the denominators.
y - 1 = -2/5x - 6/5
2/5x + y - 1 = -6/5
2/5x + y = -1/5
2x + 5y = -1
Answer:
<h2>x = 5</h2>

Answer:
1 or any normal number mate! rational no is in form p/q where q is not 0
Step-by-step explanation:
Answer:
-1.09 or 0.461
Step-by-step explanation:
The quadratic formula is : -[b plus or minus square root of (b^2 - 4ac)] divided by 2a.
a quadratic equation has 2 answers. look below:
Equation1: 5 + square root of -5squared minus 128 / 16 = 5 -3 time square root of 17divided by 16 = 0.461
Equation 2: 5-3 times square root of 17 divided by 16 = -1.09
Hope this helps
