(-36x^4y+144x²y^6) / (-4x²y) =
36xy*(x³+4xy^5) / (-4x²y) =
-9*(x³+4xy^5) / x
Answer:
B.
Step-by-step explanation:
First angle 1 and 2 add up to 180 and then angle 2 and 3 also add up to 180. So angle 2 is common hence both are congruent to each other.
Answer:
Gradient = -2/3
y-intercept = 7/3
Step-by-step explanation:
Convert the equation in y = mx + c form, m is the gradient and c is the y-intercept
2x + 3y = 7
3y = -2x + 7
y = -2/3x + 7/3
Answer:
24
Step-by-step explanation:
XW=WY=12
If the opposite angle is 30, the hypotenuse is double the small side.
XZ=XW=2·12=24
Answer:
y = 57 - 3x
Step-by-step explanation:
Alice collected 57 skipping stones. And she skipped 3 stones a minute on her pond.
So. if y represents the number of stones left to her and x represents the number of minutes, then by the condition given we can write
y = 57 - 3x ..... (1)
So, this is equation of a straight line in the slope-intercept form. (Answer)
