Answer:
y will increase by 8
Step-by-step explanation:
y = 8x+2
We increase x by 1
Replace x with x+1
y = 8(x+1) +2
y = 8x+8+2
y = 8x+2 +8
perpendicular
the parameter of B figure is
12+9+9+5
35
as we know the scale factor is 7/2
so the parameter of A figure is
35×7/2
122.5
1.
2.
let the number be x.
a number decreased means
x-
and the sum of the number and 4 is
x+4
to put the expression together, we get. put them in parentheses
x - ( x+4 )
= x - x -4
= - 4
r=-4
make r the subject and solve
