Whoever answer this question I will mark brainliest pls I need help 1.Given that ∆DEF ≅ ∆ZXY,
and
. Find 2.An iron rod 5m long is placed against the wall in such a way that the foot
of the rod is 3m away from the wall. Find how high the top of the iron rod
reaches in the wall?
3.Name the triangle in which two altitudes of the triangle are two of its
sides.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

yes the data was not prsented

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
