Answer:
A) -13p^33q^-2 or -13p^3/q^2
B) 8x + 5y - 7
C) 15x^2 -23x + 4
Step-by-step explanation:
A) 169/(-13) = -13 p^4/p = p^3 q/q^3 = 1/q^2 which can be written as q^-2 and r/r is 1. So if you put this all together you get -13p^33q^-2 or -13p^3/q^2
B) 3(x +2y) + 5x - (y + 7)
3x + 6y + 5x - y - 7 distributive property
3x + 5x + 6y - y -7 combine like terms
8x + 5y - 7 Answer
C) (3x-4) (5x - 1) Foil multiply the first terms in each parenthesis. the outer terms, the inner terms and the last terms
(3x)(5x) + (3x)(-1) + (-4)(5x) + (-4)(-1)
15x^2 -3x - 20x + 4
15x^2 -23x + 4
Answer:
x=±3 sqrt(2)
Step-by-step explanation:
3x^2 - 6 = 48
Add 6 to each side
3x^2 - 6+6 = 48+6
3x^2 = 54
Divide each side by 3
3x^2/3 =54/3
x^2 = 18
Take the square root of each side
sqrt(x^2) =sqrt(18)
x =sqrt(18)
We know sqrt(ab) = sqrt(a) sqrt(b)
x =sqrt(9)sqrt(2)
x=±3 sqrt(2)

Answer:
3
Step-by-step explanation:
in slope-intercept form, the slope is the x's coefficient, which in this case is 3,
so, m=3
