Answer:
Step-by-step explanation:
<u>Given</u>
<u>Substitute x with -3</u>
-
h(-3) = (-3)^-2 = 3^-2 = 9^-1 = 1/9
#6
D. 3.0 x 10^8
#7
A. y = 3.5x + 7
#8
B. 5
Sub 5 for x
x2+4
5*2+4
Gemdas or Pemdas
10+4=14 so the value is 14.
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
X=y-4 Let's make this eqn 1 and
2x-5y=3 this eqn 2..
Two things are possible here...
Its either you substitute for x in equation 2... Or you substitute for y...
x=y-4 put this in the equation 2..
2x-5y=3.. Replace the x with (y-4)
2(y-4)-5y = 3...
Since this is In the option no point in substituting for y...
Hope this helped...?
