Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
4.2 × 10⁻⁵
Step-by-step explanation:
The decimal point must be after the first non-zero digit.
⇒ 4.2
Multiply 4.2 by a number that results in 0.000042. That number is 0.00001 or 10⁻⁵.
⇒ 4.2 × 10⁻⁵
Answer:
Sci. Notation= 4.2 x 10 to -5th power
