The value of a = -12
Step-by-step explanation:
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Determining the value of a
Given the equation
[tex]\frac{8^{-55}}{8^a}=8^{-43}[/tex]
Apply the exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\:8^{-55-a}=8^{-43}[/tex] ∵ [tex]\frac{8^{-55}}{8^a}=8^{-55-a}[/tex]
[tex]-55-a = -43[/tex]
Add 55 to both sides
[tex]-55-a+55=-43+55[/tex]
Simplify
[tex]-a=12[/tex]
Divide both sides by -1
[tex]\frac{-a}{-1}=\frac{12}{-1}[/tex]
Simplify
[tex]a=-12[/tex]
Therefore, the value of a = -12

Answer:
Point A: (-3,3)
Point B: (3, -2.5)
Point C: (-4, -4)
point D: (1,0)
Step-by-step explanation:
Answer:
1. Point A (-3, 3)
2. Point B (3, -2.5)
3. Point C (-4, -4)
4. Point D (1, 0)
Explanation:
to identify the coordinates of each point, begin by locating where the point is across from the x axis and y axis.
These coordinates are in the form (x, y)
where x is the horizontal [left and right] orientation or location in respect to the x axis, and y is the vertical [up and down] orientation or location in respect to the y axis.
Point A is 3 units to the left and 3 units up from the origin [(0, 0)] so the coordinate of this point is (-3, 3).
Point B is 3 units to the right and 2.5 units down from the origin [(0, 0)] so the coordinate of this point is (3, -2.5).
Point C is 4 units to the left and 4 units down from the origin [(0, 0)] so the coordinate of this point is (-4, -4).
Point D is 1 unit to the right and 0 units down from the origin [(0, 0)] so the coordinate of this point is (1, 0).

I need help with a geometry problem! It’s about reflection
Answers
Step-by-step explanation: Here, we're asked to reflect ΔQRS over
the x-axis so we begin by reflecting point Q over the x-axis.
Since point Q is 2 units below the x-axis, point Q will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as Q' which is the ordered pair (1, 2).
Next we reflect point R over the x-axis.
Since point R is 2 units below the x-axis, point R will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as R' which is the ordered pair (3, 2).
Now connect the points to get our reflection.
Next we reflect point S over the x-axis.
Since point S is 6 units below the x-axis, point S will reflect
over the x-axis to a position 6 units above the x-axis.
We label this point as S' which is the ordered pair (1, 6).

what is x's value 4x+4y=44 y=2x+2
Answers
Answer: x = 11 + y
Step-by-step explanation: Simplifying
4x + -4y = 44
Solving
4x + -4y = 44
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
4x + -4y + 4y = 44 + 4y
Combine like terms: -4y + 4y = 0
4x + 0 = 44 + 4y
4x = 44 + 4y
Divide each side by '4'.
x = 11 + y
Simplifying
x = 11 + y
