Answer:
Step-by-step explanation:
Prime factorize those numbers.
160= 2^5 *5
243 = 3^5
160 * 243 = 2^5 * 3^5 * 5
Taking the fifth root, we get
6(fifth root( 5))
Answer:
Option B
Step-by-step explanation:
-1/2x≥4
1) Multiply both sides of the inequality by the reciprocal of -1/2: (-2)
x≤-8
Graph x≤-8 as a line. Remember that lesser negative values go to the left!
ALSO don't forget when you multiply both sides of an inequality by a negative number the inequality sign flips.
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
The first thing we need to do is combine like terms
6c+14=-5c+4+9c
6c+14=4c+4
-4c -4c
2c+14=4
-14 -14
2c=-10

2 2
c=-5
I hope I've helped!
Answer:
x=5/4 + 5b/4
