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

HELP ASAP<br> Find E, the midpoint of RD if R (4,-5) and D (2,3)
Arturiano [62]

Answer:

(3, - 1 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} )

here (x₁, y₁ ) = R (4, - 5 ) and (x₂, y₂ ) = D (2, 3 )

midpoint = ( \frac{4+2}{2} , \frac{-5+3}{2} ) = ( \frac{6}{2} , \frac{-2}{2} ) = (3, - 1 )
