X=3 . ok well ur gonna do reverse mathematics so start by subtracting 2 from 17 (bc the oppistite of addition is subtraction) an then rewrite the equation. 5x=15 and then divide 15 by 5 and it equals 3 and then do it all over again meaning put the equation as it was but with the value. 5x3+2=17 and it all makes sense. im so sorry i answered so late i just got this question recommended to me.

Answer:
f(-4) = -2
Step-by-step explanation:
To find f(-4) use the "piece" of the function rule defined for x < -3 (because -4 is less than -3). That part of the rule says the output (range) value is x + 2, so f(-4) = -4 + 2 = -2.
Bx must be the sum of the numbers in the bracket and c must be the product. So we need to choose 2 numbers that multiply to make 3 and add to make -4.
A negative x negative = positive so
-3*-1=3
-3-1=-4
Therefore:
(x-3)(x-1)
The coordinates of the point can be solve using the fomula:
x = x1 + r( x2 - x1 )
y = y1 + r( y2 - x1)
where r is the ratio that partitions the segment
x = x1 + r( x2 - x1 )
x = 3 + 1/3( 8 - 3 )
x = 3 + 1/3( 5 )
x = 14/3
y = y1 + r( y2 - x1)
y = 2 + 1/3( 15 - 2)
y = 2 + 1/3( 13 )
y = 19/3
so the coordinate is ( 14/3 , 19/3 )
