Replace the x in x^2 + 5x - 1 by x+3:-
g(x) =
(x+3)^2 + 5(x+3) - 1
= x^2 + 6x + 9 + 5x + 15 - 1
= x^2 + 11x + 23
- thats g(x)
The equation would be y = 25x + 50
In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking.
Since she saves $25 a month for 7 months, we can find the total amount as:
25*7 = 175
Then we can subtract that from the total she has saved to find the amount for the gift.
225 - 175 = 50
Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.
Divide 384 by 12 then multiply it by 5 to give you 160
line N has slope m = 
given a line with slope m then the slope of a line perpendicular to it is
= - 
thus line N has slope - 
=
Nathan has a 25% chance of NOT being allergic to the drug. And then that 25% is 98% accurate so:
25% x 98%
0.25 x 0.95 (changed to decimals)
= B) 0.2450
