Answer:
d) neither
Step-by-step explanation:
Given equation is 7x - 5 = 4y -6 ...…...... (1)
Substitute x = 2 and y= 4 in equation (1)
7(2) -5 = 4(4) -6
9 ≠ 10
a) is not satisfied
Substitute x = 3 and y= 6 in equation (1)
7(3) -5 = 4(6) -6
16 ≠ 18
b) is not satisfied
c) is also not satisfied
<u>Final answer</u>:- neither
We need to remember that:
xyz = (x)(y)(z)
if x, y and z are perfect cubes, then xyz would also be a perfect cube
Also,
(x^n)^m = x^(mn)
if it is a perfect cube, then it can be factored into the expression (x^n)^3, wherein n is a whole number.
All should be a perfect cube, given
215x^18(y^3)(z^21)
By writing the terms separately, we would see which one is to be changed.
215 = 5*43, we see this is not a perfect cube, we could changed it to 6^3 or 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
The other terms are perfect cubes except for the first one. So the correct answer would be the last option, 215 should be changed.
Answer:x<-7
Step-by-step explanation:
3x -15x - 30 > 54
-12x-30>54
-12x<54+30
I moved 30 from left side to right which becomes positive and > becomes <
-12x<84
-12x/-12<84/-12 I used my calculator to do this
x<-7
