Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive
Answer:
y = (x +4)(x +2)²(x +1)
Step-by-step explanation:
The function has a generally U shape, so is of even degree. The zero where the graph touches, but does not cross, the x-axis is a zero of even multiplicity. The minimum degree of a function that matches this description is 4. It will have zeros at x=-4, -2 (multiplicity 2), and -1. The constants in the corresponding binomial factors will be the opposite of these values, so the factored form is ...
y = (x +4)(x +2)²(x +1)
__
The multiplicity of a zero is the power of the corresponding factor.

Answer:
To make x the subject of the equation means to solve the equation for x (get x by itself on one side). We do the order of operations in reverse, because we are using inverse operations. First, add the 2 to both sides (to keep the equation “balanced” we must do the same thing to both sides). y+2=3x. Then divide both sides of the equation by 3 (or multiply both sides by 1/3.
Step-by-step explanation:
It's the third one. The first and last ones(the blocks in the figure) are complete while the other two (2nd and 3rd) are partial. The Third being longer than the second.
