x² + 5x + 6 = 0
(x + 3)(x + 2) = 0
x + 3 = 0 x + 2 = 0
x = -3 x = -2
Which rule describes the composition of transformations that maps ABC to A"B"C"?
O T-6.-2°rx-axis(x, y)
O rx-axis° T-6 -2(x, )
O T-6.-2°Ro, 90°(x,y)
O RO, 90° T -6, -2(x, y)
Answer:
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2) ⇒ B
Step-by-step explanation:
Let us revise some rules of transformation
If the point (x, y) reflected across the x-axis, then its image is (x, -y), the rule of reflection is rx-axis (x, y) → (x, -y)If The point (x, y) reflected across the y-axis, then its image is (-x, y), the rule of reflection is ry-axis (x, y) → (-x, y)If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)Look at the graph and list the vertice of each triangle
∵ A = (5, -5) and A' = (5, 5)
∵ B = (1, -2) and B' = (1, 2)
∵ C = (1, -5) and C' = (1, 5)
→ The signs of y-coordinates of all vertices of ΔABC are opposite
in ΔA'B'C'
∴ Δ ABC is reflected across the x-axis
∴ The rule is rx-axis (x, y) → (x, -y)
∵ A' = (5, 5) and A" = (-1, 3)
∵ -1 - 5 = -6 and 3 - 5 = -2
∵ B' = (1, 2) and B" = (-5, 0)
∵ -5 -1 = -6 and 0 - 2 = -2
∵ C' = (1, 5) and C" = (-5,3)
∵ -5 - 1 = -6 and 3 - 5 = -2
→ That means every x-coordinate in Δ A'B'C' added by -6 and every
y-coordinate add by -2
∴ Δ A'B'C' is translated 6 units to the left and 2 units down
∴ The rule is T (x, y) → (x - 6, y - 2)
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2)
Transformation involves changing the position of a shape.
The transformation rule is (b) rx-axis° T-6 -2(x, y
First, triangle ABC is rotated across the x-axis.
The rule of this transformation is represented as: rx
Next, the resulting shape (i.e. triangle A'B'C') is translated 6 units left and 2 units down.
Using the coordinates of A as a guide, we have:
[tex]\mathbf{A = (5,-5)}[/tex]
Apply the first transformation: Rotate across the x-axis
[tex]\mathbf{A' = (5,5)}[/tex]
Apply the second transformation: Translate 6 units left, and 2 units down
[tex]\mathbf{A" = (5 - 6,5-2)}[/tex]
[tex]\mathbf{A" = (- 1,3)}[/tex]
Hence, the transformation rule is (b)

A 1st degree polynomial function whose graph intercepts the y-axis at 8.
Your answer can be anything in the form y = mx+8 where you replace m with any real number.
You start with y = mx+b, and then replace the b with the y intercept 8.
The y intercept is where the polynomial crosses the y axis.
The value of m does not matter. So you could have y = 2x+8 or y = 3x+8 for instance. Replace m with whatever your favorite number is.
We want to find a polynomial of 1st degree that passes through the y-axis at y = 8.
The polynomial is: y = a*x + 8
Where the coefficient a can be any real number different than zero.
Let's see how to find that polynomial.
Remember that the degree of a polynomial gives us information of the maximum exponent that the polynomial has.
So if the degree is 1, then the polynomial maximum exponent is 1.
From this we can conclude that the polynomial will be something like:
y = a*x + b
Now, this is just a linear equation, where a is the slope and b is the y-intercept.
We do know that this intercepts the y-axis at 8, then we define b = 8, and we get:
y = a*x + 8
This is our polynomial, where the value of a can be any real number different than zero (we use that restriction because if a = 0, then the degree of the polynomial would not be 1).

Step-by-step explanation:
Answer: -3
Step-by-step explanation: The additive inverse tells us that if we
add a number and the opposite of that number, the result will be 0.
So in this problem, 3 + (-3) = 0.

Is 1.888... an irrational number? (i have a 1 in math :C)
Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.
