Answer:
The correct answer is C. y = 3/4x - 12
Step-by-step explanation:
In order to find this, we must first note that the slope will be 3/4. We can tell this because parallel lines have the same slope. Next, we use that along with the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - -18 = 3/4(x - -8)
y + 18 = 3/4 (x + 8)
y + 18 = 3/4x + 6
y = 3/4x - 12
Step-by-step explanation:
(a×b^-3×c^-3)⁵ / (a^-3×b⁴×c⁴)^-5
let's look at the numerator (the top) first :
a⁵×b^-15×c^-15
and now the denominator (the bottom) :
a¹⁵×b^-20×c^-20
both divided are (due to the commutative rules of multiplication we can split this first into the parts of the individual variables, and then multiply them all with each other) :
a⁵/a¹⁵ = 1/a¹⁰
b^-15 / b^-20 = b^(-15 ‐ -20) = b⁵
c^-15 / c^-20 = c⁵
so we get as result :
b⁵c⁵/a¹⁰
For #7 - part a: greatest common factor (GCF) is 5.
Part b: cross out everything BUT 10 & 20.
