Answer:
y = 3x
Step-by-step explanation:
Given line slope = m = -1/3
perpendicular line slope = - 1/m = 3
Point slope form through point 1, - 3
(y+3) = 3 ( x-1) expand and rearrange
y -3 = 3x- 3
y = 3x - 6
The measure of EF from the given diagram is 6 units
<h3>Secant secant theorem</h3>
The theorem states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external parts is the same as the product of the other external part.
Mathematically according to the given figure;
4(4+2x) = 5(5+x)
Expand
16 + 8x = 25 + 5x
Collect the like terms
8x - 5x = 25 - 16
3x = 9
Divide both sides by 3
3x/3=. 9/3
x = 3
Find EF
EF = 2x
EF = 2(3) = 6
Hence the measure of EF from the given diagram is 6 units

Answer:
less than twenty five
v
25 - <u>(2n + 8)</u> < the sum of 2 times N plus 8.
Step-by-step explanation:
- 2 /15 - ( - 9/10 )
-2/15 + 9/10 multiply fraction #1 by 2 an fraction #2 by 3 to get
-4 /30 +27/ 30 = 23/30
