Answer:
y=4x+17
Step-by-step explanation:
y-b=m(x-a)
y-5=4(x--3)
y-5=4(x+3)
y-5=4x+12
y=4x+17
The number in the monomial 125x¹⁸y³z²⁵ that needs to be changed to make the expression a perfect cube is 25
To determine the number to be changed in order to obtained a perfect cube, we shall determine the cube root of each entity. This is illustrated below
Cube root of 125
³√125 = 5
Cube root of x¹⁸
³√x¹⁸ = x⁶
Cube root of y³
³√y³ = y
Cube root ofz²⁵
³√z²⁵ = z^(25/3)
From the illustration above, we can see that 25 is not a perfect cube.
Thus, 25 needs to be changed in order for the expression 125x¹⁸y³z²⁵to be a perfect cube

Answer:
28/9
Step-by-step explanation:
Answer:
3 1/9
Step-by-step explanation:
2 1/3 divided by 3/4
= 7/3 divided by 3/4
= 7/3 x 4/3
= 7 x 4 over 3 x 3
= 28 over 3 x 3
= 28/9
= 3 1/9
