Hi,
All you have to do is to use Thales 's theorem.

Answer:
touches
crosses
Step-by-step explanation:
is said to be a zero of a function if
A zero say has a "multiplicity" equal to , if the factor appears in the polynomial.
When a real zero of a polynomial function is of even multiplicity, the graph of <u>touches</u> the x-axis at , and when it is of odd multiplicity, the
graph of <u>crosses</u> the x-axis at .
Answer:
a) y=3x-11
b) y=-1/3x-1
Step-by-step explanation:
First find the slope of the line
rise/run
rise is 3
run is 1
so slope is 3
since this line is parallel to "a", the slope of "a" will also be 3
the equation of a will be
y-y1=3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=3(x-3)
y+2=3x-9
y=3x-9-2
y=3x-11
since this line is perpendicular to "b", the slope of "b" will also be reciprocal negative , -1/3
y-y1=-1/3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=-1/3(x-3)
y+2=-1/3x+1
y=-1/3x+1-2
y=-1/3x-1
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuseAnswer:
Step-by-step explanation:
Answer: D
9x - 12
Step-by-step explanation:
3(2x-4)+3x
Use the distributive property
6x-12+3x
Then combine like terms
9x-12
SO THE ANSWER IS D
