Noah and Lin are each trying to solve the equation 2² - 6x + 10 = 0. They know that the solutions to z? = -1 are i and –i, but they are not sure how to use this information to solve for z in their equation.
Lin decides to solve the equation using the quadratic formula. Here is her work:
X
-btvb2-4ac
2a
-(-6)/(-6)2-4(1)(10)
X
2(1)
61V36-40
Lin knows 36 – 40 is a negative number and isn't sure what to do next. Show how Lin can write her solution
using i.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
