laila [671]
Hi!
Shawna is correct because since it's multiplied to the  5-n you have to do the opposite which is division. 
Dexter is also correct because after distributing you can continue solving, there is nothing wrong with that. 
Hope this helps!

Answer:

A. 13 + t = 17

Step-by-step explanation:

The top rectangle shows 13 and t, the 13 and t rectangle is the same size as the 17 rectangle so 13 + t = 17. It's not multiplication as there's no multiple's of 13 or t on the diagram.

I need help solving this problem
Alex787 [66]

Answer:

(x,f(x)) = (-1,8) -- Another point

a = 8

Step-by-step explanation:

Given

f(x) = a|x|

(x,f(x)) = (1,8)

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in f(x) = a|x|

8 = a|1|

Remove absolute bracket

8 = a*1

8 = a

a = 8

Substitute 8 for a in f(x) = a|x|

f(x) = 8|x|

Let x = -1

f(x) = 8|-1|

Remove absolute bracket

f(x) = 8*1

f(x) = 8

So, another point is:

(x,f(x)) = (-1,8)

Solving (b): The value of a

This has been solved in (a) above

a = 8
