Answer:
C. 5
Step-by-step explanation:
Triangle BED is enlarged by scale factor 4.
(25-x)/4 = x
Multiply both sides by 4.
25-x = 4x
Add x on both sides.
25 = 5x
Divide both sides by 5.
5 = x
See,u have y+5x=6 ( * =multiplication sign)
and x=-1,0,1
so ,u have to do is substitute x with numbers u have
so,for -1,u have y+5*-1=6
=y= 5+6= 11 ( u multiply 5 by -1 u get -5 but when u change the sides u get it as 5 ...so 5 + 6 =11)
(2)y+5*0=6
=y=6-0=6
(3)y +5*1=6
y=6 -5=1
( i hope this helped :) )
Answer:
see explanation
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 8 - 5 = 11 - 8 = 14 - 11 = 17 - 14 = 20 - 17 = 23 - 20 = 3
This indicates the sequence is arithmetic
The common difference d = 3
The first term a₁ = 5 and
a₈ = 23 + 3 = 26
the answer is C.
by the formula vertex (xv,yv) y=a(x-xv)²+yv
