Answer:
1
Step-by-step explanation:
We have the function

and we want to know the value of
.
The first step is to find
; we can subtract 1 from it at the end! But what does
mean?
Basically, we're saying <em>"what is the value of the function when </em>
<em> ?"</em>
So, we simply replace
with 3 in the function, and we get:
.
Finally, we subtract 1 to find
.
Answer:
x = -3.5
Step-by-step explanation:
1(x-2) = -5.5
x-2 = -5.5
+2 +2
x = -3.5
Answer: x = 70, y = 110, z = 85
Step-by-step explanation:
If BE = CD, then using corresponding angles (are equal), x = 70
If x = 70, then 70+y = 180 (angles on a straight line)
y = 110
And z = 85 (corresponding angles again): angle ABE = angle ACD

So y=2x is the only answer that fit y=kx, while k=2
